Koss KPH30iK Retro Style On-Ear Headphones, in-Line Microphone and Touch Remote Control, D-Profile Design, Wired with 3.5mm Plug, Dark Grey and Black

The Koss KPH30iK are incredible for around $30. They’re super lightweight, comfortable for long listening sessions, and have a simple, clean look that doesn’t feel cheap. Sound quality is where they really stand out. They have a warm, balanced tuning with fuller bass than you’d expect from an open on-ear design. Mids are clear and natural, making vocals sound especially good, and the treble is smooth and easy. They sound open and lively, not thin or compressed, and easily outperform many headphones that cost significantly more. Build quality is basic but smart. The lightweight plastic construction keeps them comfortable, and while they don’t feel premium, they also don’t feel fragile. If you want great sound on a tight budget, these are an easy recommendation. A true classic from Koss and one of the best values in headphones. On a side note, I would also recommend the Koss Potra Pros.

While I wouldn't classify myself as being an audio snob, I do have decent collection of various headphones (some are good, some are meh), which include but are not limited to the Sennheiser HD598 & HD700, Epos G6 Pro, HE400se, V-Moda Crossfade Wireless and two generations of Skullcandy Crushers (1st + Evo). Most of my wired audio is hooked up to the Sennheiser GSX 1000 DAC/AMP, nothing fancy but geared towards computer use (Music, Gaming and productivity use). The Koss KPH30i headphones are by far one of my favorite. I'd put them up their with my Sennheiser HD598s in terms of sound, not the same but they hit in the same general ball park. If I had to explain the difference between the two, the Senns are more punchy and warm, while the Koss headphones are buttery smooth and warm. They work extremely well for gaming with the GSX 1000's virtual surround, and for music the audio just melts into your ears assuming its the right genre. I'm talking about new retrowave and anything with a bit of synth in it. Lo-fi is great. 80s Metal works well. In fact almost everything from the 80s will sound awesome. Some examples include Michael Jackson's Billie Jean, Wang Chung's Dance Hall Days, Duran Duran's Rio, Oingo Boingo's Weird Science and Billy Idol's White Wedding to name a few. Comfort wise, they are so light I forget that I am wearing them. Default pads are uncomfortable, so I highly recommend slapping some Yaxi pads on them OR Grado G cushions. In short, I highly recommend these. They are not going to be the best headphone money can buy, but they will hit well above their weight class, so much so I find myself wearing using them more than any of the other headphones I have on hand. If I was in the market for a pair of Sennheiser open backs, I would buy these first as they get you close to that territory for very little money, and more importantly they are addictingly fun. They lose a bit of detail, but offer up a buttery smooth experience that is both warm and slightly intimate. Note: The headband is not the most sturdy. It will probably break at some point. If that happens, or the wire goes out, before you chuck them in the trash remember you can replace the headband and even mod the cables to be detachable. Its extremely easy and cheap to do, and there is a ton of content available showing how to do this. These are heavily moddable headphones.

This headphone is difficult to review, because i love it so much. Pros: 1. the sound is amazing for the money, i have paid for headphone costing 5x as much but don't sound as good. 2. the clamp force is perfect, i used it for hours, no issues at all, i can use this all day gaming and listening to music. 3. come with its own mic, which is a feature often overlooked. Cons: 1. quality is just terrible, cheap plastic headband, in fact this is my second pair, i purchased one from DROP just a few month ago, and the headband, broke in 3 places just from normal daily use. no abuse, no drop, it broke from just putting it on and taking it off. 2. no detachable wire, after another few weeks of using the broken headband khp30, the wire broke as well, i finally had to trash it, because left ear no longer produce sound. 3. you can forget about noise cancellation, this should be used at home in a quiet place to enjoy your game, movie, music. otherwise you will hear everything inside the house and outside. Conclusion: I so wanna give this a 3 star because of the poor quality, but i just love the sound and comfort too much. 4 starts it is. i think this could be a great headphone, if Koss just spend a little bit more money and improve on the quality on the parts used to make this headphone. i don't mind paying $5 to $10 more. the headband should be enforced with METAL, also make the wire detachable. i hate to buy a 3rd one, i love the sound and comfort, but i am afraid this new pair will break within 6 month as well.

Like high-quality music? See these on sale for 20$? Buy them without question, then buy whatever else you want. 30$? Still buy them. Seriously, budget audiophiles and teenagers listen up: these are THE best purchase in Portable Audio, barring NONE. If they weren't literally MADE to deliver the best sound with the cheapest price, they would compete in the 200$+ headphone market EASILY. There is nothing under 80$ that sounds remotely as good as these. Even above that price, I only divert in specific situations. They may not suit your exact need just yet, but I promise you won't regret the purchase over time. I've owned them for about 8 months now and use them daily, unlike any other headphones I own. As a hobbyist pseudo-audiophile, these have blown my mind in terms of sound quality, even ignoring the cheap 30$ price. (20$ on sale every now and again, snatch some up!) I legitimately have bought 5 of them. I use them as my primary headset for my phone and calls, their low-profile design makes them perfect for wearing under a helmet when I go longboarding, and the audio experience is just fantastic for walking around the house and music discovery. These headphones are extremely 'fun' sounding. Treble is clear and crisp, but not sibilant. Mids are present and effective, though not entirely a focus. The bass response is deep, quick, and punchy. I enjoy them the most with bouncy styles of EDM and similar, but they have paired well with everything really. Their open-back design gives them a wide soundstage that can be further widened by pad swaps (Grado pad swap or Yaxi pads). I use a pair with the Grado swap sometimes, and the Yaxi pair other times. They react well with all of my amps, including tube amps, but also work great with integrated amps like phones. They arent extremely detailed, but they are my instant pickup when wanting to listen to music I already like, or new music that I don't need to resolve all the nuances in. Great for gaming on the go, and for awkward setups where you join discord calls on a phone or move around your house alot. Work well with my Oculus Rift. Everyone should own a pair. I prefer these to my SHP9500s, and especially over my AKG 7xx(200$...). Overall, these fit a variety of purposes and every single music listener should own a pair. At the sale price of 20$, I would suggest owning two. Igift these to my friends and family to show them how silly high-quality audio can be; sometimes it comes in a 300$ package, sometimes it comes in a 20-30$ pair of odd library-looking headphones. Don't knock on them; I wish they were my first audio purchase, but comparing them to my multiple 200+$ headphones and headsets, and I still often favor the sound of these on top of their any-situation use-case. NEGATIVES: -They do bleed alot of sound, as they are open-back. I could hear most of my friend's phonecall sitting near him yesterday. They also let a ton of noise in, which I prefer as they are open-back, but it does make me raise the volume alot when on-the-go. -They sometimes sound like they are a but distorted or buzz at certain specific frequencies, like on phone calls. I've found that to be caused by bits of vibrating hair inside various parts of the housing, but have always been able to resolve it with a quick cleaning (easy to clean and remove housing/drivers). -The comfort can be an issue sometimes. Yaxi pads are the best upgrade for this, for sure. -The Grado pads arent the best for practical use, but are fun and better for gaming/movies in my opinion. The standard pads can be made better by crushing them and breaking them in, but will never be as nice as the Yaxis. -The mic is not the best obviously, but it does sound good. Better than alot of gaming headsets to be honest. -The cable twists and tangles near the Y split often. A little annoying, but you could even recable these for MMCX or another style of 3.5MM if you like. Overall the cable is nicely rubberized but not the best of course. BEST USE-CASES FOR THESE: -Under-helmet audio, lightweight openback listening for things like running, skating, etc. -Taking phone calls, short term gaming headset. -Modding without fear, learning to modify headphones without risk of high costs in detroying them. -Gifts, for literally anyone you know. -IEM replacement in terms of usage (if you find in-ears uncomfortable but over-ears or on-ears too bulky, and don't need the sound isolation). -Baseline for audio comparisons with any other item in the 'budget' or 'any-situation' market space. -EDM, Rock, Metal, Pop, Synth, Hyperpop, etc genres where highs/vocals are not the specific focus. DEVISION TREE: If I listen to music, these are my first consideration. I switch to other options only in these cases... -Needing long-term gaming headset, better mic, SUPER BOOMY BASS, extreme long-term comfort, or closed back? I switch to my Beyerdynamic MMX300g2. -Listening to vocal-heavy, classical, or other treble-focused music, and dont need a mic? Switch to my SHP9500s, sometimes. -Needing an open-back headset with a separated mic for PC usage and other gaming needs? Switch to my AKG K7XX+Modmic. -Needing to go on a plane? Switch to modified clones of Beats Studios (drivers replaced). -Needing forward-focus, no imaging or soundstage? Switch to ATH M50s. -Needing detail and zen? Switch to IEMs: BlonBL-03 or Moondrop Starfields. In every other situation, these are what are on my ears.

After reading positive reviews, including one by Cnet's Steve Guttenberg, I purchased these headphones to add to my collection of low-cost semi-open-back headphones (Koss Porta Pro, Koss KTX-PRO1, Superlux HD681 Evo, original Austrian-manufactured AKG K240). I'll focus on comparing this with the highly acclaimed Koss Porta Pro. Both headsets are new, so they haven't been "burned in" by having hours of music played through them, which many audio experts claim can open up the sound to be even better than when new. (Instead of my 20-year-old Porta Pro, I'm using a brand new Porta Pro Limited Edition, so that neither headset has benefited from burn in.) COMFORT: Initially the KPH30i is more comfortable than the Porta Pro. for 2 reasons: 1) its kidney-shaped earpieces are larger than the round earpieces of the Porta Pro, so the pressure is more distributed. 2) The KPH30i has a soft rubber suspension band that sits atop the head, while the Porta Pro has a narrow, unpadded metal band that sits atop the head. The clamping force is reasonable, just enough to keep the earpieces from slipping. I wore these headphones comfortable over my eyeglasses. It doesn't appear that the foam cushions are replaceable; they may be, but I don't want to risk pulling the cushions if they're glued on. The Porta Pro cushions are replaceable. SOUND: Excellent, especially at this price which is about $15-25 less than various versions of the Porta Pro. If you love the famous sound signature of the Porta Pros, you'll probably love the sound of the KPH30i, because the drivers are probably very similar, if not identical (both are rated at 60 ohms impedance, frequency response of 15-25,000 hertz, efficiency of 101 dB SPL. Both headsets produced the same ample loudness from my Samsung S8+ cellphone.) Both headsets being semi-open designs, they both offer a large "soundstage", which means that the voices and instruments don't sound entirely as if inside your head, but also sound as if the sound sources are around you, with broad stereo imaging. I played the same music on both headsets, and the KPH30i sounded nearly identical to my non-audiophile ears. Steve Guttenberg wrote that the Porta Pro is more transparent and clear, while with this KPH30i: "Treble detail is soft, the KPH30i isn't by any stretch a high-resolution headphone. There's a fuzziness to the sound to be sure, but it didn't intrude or detract from the music." He still loves the KPH30i, and I do, too. Like the Porta Pro, this KPH30i has a 4-foot, non-removable cord. The cord is thicker than the one on the Porta Pro. The KPH30i has a straight plug; I wish it were angled so that it wouldn't protrude 90 degrees coming out of the cellphone. A nice feature is that the plug has a spring-like coil that offers strain relief where the cord joins the plug. Overall, th KPH30i appears very well constructed and I'm guessing it will be durable if handled carefully. November 21st, 2018: I see that the Koss website sells replacement cushions for the KPH30i. Five dollars for 2 pairs, available in either gray or blue colors. The blue version is for the white KPH30i, but why not go crazy and place them on your gray KPH30i? ;-) March 10th, 2020 update: I improved the comfort and sound with 2 products available on Amazon: Yaxi earpads for Koss PortaPro (they also fit on these KPH30i) which bring more comfort and audio improvement, and HIDIZS S3 Portable Headphone Amp/USB C DAC/Audio Amplifier which plugs directly into the USB Type-C jack of my Samsung S9+ cellphone.

I enjoyed these Headphones! They had very nice high's and mids. The bass is there but not too boomy. They are great for easy-listening. The comfort on these is terrible though. The clamping force plus the big flat earcups hurt my ears quiet bad. There are some mods I mention below that helped considerable. Namely, the Grado Pad mod. I also hear you can heat up the plastic headband to reduce the clamping force. I didnt try that, just the pads helped considerably. Ultimately I chose the KPH40 as the best budget heaphone. More details below... --- MY HUNT FOR THE BEST BUDGET HEAPHONES: (I use my headphones for 80's Rock, 90's Alternative, Oldies, Classical, and plenty of TV and Movies) - SHORT VERSION...BUY THE KOSS KPH40'S AND SOME YAXI PADS! LONG VERSION... FIRST I HAD THE PX-100-i's for like 10 years. Loved them, but the connector broke a few years back. THEN I got the PX-100-ii's. I didn't like it as much as the first iteration. Way too much Bass! And the bass bled like crazy. They sounded super muddy. But everything else sounded like my old px-100's. Then a few months ago, THOSE broke at the connector (I'm nice to my headphones, they get plugged into my computer and stay there, there's really no reason for those connectors to go faulty, just bad manufacturing). Then I found out that Sennheiser was no longer making ANY PX-100's anymore, so I had some research to do... NEXT WERE THE KOSS PORTAPROS https://www.amazon.com/gp/product/B00001P4ZH/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 - The sound is 'soft' for the mids and uppers, and a slightly boomy bass. Very easy-listening. The bass was a little too boomy for my taste, but it wasn't bad. The high's weren't sibilant, which I loved. I missed some clarity from my px-100's, but it was worth it. What I didn't like about it was that the bass bled into the mids, which made some things sound weird. Still, I liked them better than my original sennheiser PX-100-i's which is saying something. The PX-100-i's have highs that are harsh on my ears, too much sibilance. The Bass on the PX-100-i's can be a little to boomy also, but no bleeding. It had an accurate, clear sound I loved. But overall I considered the Portapro's a nice upgrade. For those of you who have trouble with it pulling your hair, my remedy was to wrap painters tape (blue to match the highlights on the headphones) around the middle section of the headband. It also keeps the headband the perfect length so I didn't have to constantly adjust it every time I took it off. This DOES make it less portable for pocket carry, but I never used that anyway. The temple pads were giving me migraines so I ripped them off. Then I replaced the foam earpads with the YAXI ones. Now they feel great! KOSS KPH30i https://www.amazon.com/gp/product/B075FBRYM1/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&th=1 - I didn't like the bleeding bass of the Portapro's, so I kept hunting. I tried the Koss KPH30i's next. VERY nice. I consider them better than the Portapro's. Slightly more clarity in the highs and the bass didn't bleed. The high's were only a little more powerful than the Portapro's, pretty much had the same 'soft' sound quality I liked in the Portapro's. The bass was a little underwhelming. I could tell where the bass was meant to be, which was nice, but it wasn't boomy at all. Like HEARING the bass, but not FEELING it. At first I really appreciated that, especially for classical, but after a few days I kind of missed the bass punch of the Portapro's. The biggest problem with the KPH30i's were they were uncomfortable! The earpads are huge and they press on my ears hard. Its not just the compression strength causing it, its the flat earcups that press against the entire ear. I could only wear it for 10 min before taking them off. So I tried the Grado Ear Pad mod, put it around the earcups and it was MUCH better. Warning, do NOT remove the original foam of the headphones. They tear and you cant get them back on. I made that mistake and now my KPH30i's high's hurt my ears because there is nothing between my ear and the driver. I wished I would have kept the original foam on, and THEN put the Grado pads over them. Instead I had to use the paper towel mod and now the high's don't hurt my ears. The hole in the pad still make a tunnel effect and I feel like that creates a pressure chamber that hurts my ears over time. I DO love the silicone resting band on this set. With that and the Grado pads, these became a lot more comfy, but I still would have to take them off after a couple hours, from my ears over-heating and the firm pressure on the ears. That combined with the lack of bass punch, I decided to keep looking. KOSS KPH40 https://www.amazon.com/gp/product/B09KZC94X1/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 - I had heard that the KPH40 was the sound 'sweet spot' between Portapro's and KPH30i's, and they were right! These are currently my favorite headphones, even more than my less-than-budget-friendly Sennheiser HD599's (see below). The KPH40's are my Goldilocks Headphones. The KPH40's sound profile are a LITTLE more V-shape than the Portapro's and the KPH30i's. A little more bass than the KPH30i's and a little more high's than the Portapro's. Perfect. The bass is just right, and very accurate. The mids are there, but not overpowering. The high's are clear but still have that 'soft', 'easy-listening' sound I enjoy from the Koss drivers. Honestly I don't think a lot of people will hear a difference between the 3 Koss headphones I tried, its very subtle. They all have the same basic sound. But the differences were enough for me to recommend the KPH40's over the others. The koss headphones I tried aren't as clear and accurate as my HD599's but I enjoy listening to music on them more. It's just more laid back while still being clear and accurate enough. It has a pleasant 'cloudiness' to the whole sound image. I think some people call this 'veiled'. That's a good description. It's just not as harsh on the ears, I could listen to them all day without pain or fatigue. I put the YAXI pads I bought for my Portapro's on them and they fit fine. Super comfy. It didn't really need it because Koss learned from the KPH30i's mistake and made these earcups small. They sit right on the ear where it needs to and it doesnt hurt. The headband is also metal instead of plastic, so you can adjust it to exactly the clamping force and shape that you want. At first, I found the metal headband too skinny, it felt like it was cutting into my scalp. It wasn't, It just felt that way. So I actually took the silicone band I loved from the KPH30i's and taped it to the inside of the metal head band. LOL, I'm not fancy. I bet you could tape some rolled up paper towel to the inside and get a similarly comfy effect. This mimics the all day comfort I always got from my PX-100's. I think any future iteration's should still keep the metal band, but maybe include the silicone comfort band from the KPH30i's, don't touch the drivers or earcups, they are great. I LOVE the ribbon style cable that doesn't tangle. I don't really need the "utility series" connector, especially when the utlity cables cost $45, so if removing that makes these headphones $30 instead of $40, please do so and make these headphones an even more ridiculous bargain! SENNHEISER HD599 https://www.amazon.com/Sennheiser-HD-599-Open-Headphone/dp/B01L1IICR2?ref_=ast_sto_dp&th=1 - At $150, I almost didn't want to mention these as budget headphones, but for those looking to become Audiophiles, I think they are the cheapest Audiophile-quality option. Some recommend the Grado SR60's or SR80's, but I don't. They have zero bass, ear canal piercing highs, and are VERY uncomfortable to wear. The earcups are flat, high compression, and unyielding. I couldn't wear them for more than 3 minutes. The sound profile of those Grado's might be good for monitoring high's and mids, but not bass, so what's the point of them? Vocals and violins only? No thanks. The HD599's, on the other hand, have a very neutral profile with a SLIGHTLY elevated bass, perfect for monitoring, IMO. The bass is present, a little punchy, but not muddy or boomy at all. While the headphones were comfy on my ears, I found that it created weird air pressure differences in my ear canal. This became very fatiguing after an hour, even at the lowest possible volume to hear the music. Probably because of the bigger, more powerful drivers. I think they started to damage my ears. After a few weeks I couldnt wear them for more than 10 minutes without my ears hurting again. The only time any budget Koss driver did that was when I had the tunnel effect going on with the Grado Cushion Mod, and even then it was at a much lesser degree. --- A NOTE ON AUDIOPHILIA... - But mostly I just recommend people don't become Audiophiles. It sucks. What a music-lover like me didn't understand was that Audiophiles don't listen to music, they monitor it. They don't absorb the entire composition, they nit-pick specific parts of it. This robs the listener of any enjoyment of the music. It kind of bother's me that they have stolen the title of "Audiophile". I think that belongs to music-lovers and music-makers. What we call "Audiophilia" should actually be called "Audiomonitoring". Calling it Audiophilia compels music-lovers like me to spend massive amounts of money on "better" headphones and audio setups to rob of us of any listening enjoyment we previously had with our $40 budget headphones, and rob our wallet while they are at it. I don't mean to insult or begrudge Audiophiles for a hobby they enjoy, I just don't like it when they are propped up as experts of the best sounding equipment. They aren't. They are experts for the best MONITORING equipment for sound engineers. If you enjoy music, I recommend you get a "consumer" headphone. I recommend you get the Koss KPH40. I like my KPH40's the best for listening to Music, TV, and Movies. Even over my Sennheiser HD599's. Its true that the HD599's have better clarity, but I enjoy music more with my KPH40's because I'm not hearing harshness or noises that the sound engineers never meant people to hear. Sometimes I felt like I was hearing TOO MUCH accuracy on the HD599's, like things the orchestra didn't want us to hear. I couldn't ENJOY my music because I was MONITORING it too much. I heard too much noise, not enough music. And I didn't have a CHOICE to enjoy the music, I HAD to monitor it. Audiophiles are nit-picky sound analysts, so take their hard-earned advice with that in mind. OK, A short message on Amp/DAC's. Don't bother. I have a Dragonfly Cobalt Amp/DAC. It costs $330. While it DOES make all my headphones sound better, it's practically negligable. MAYBE a 3-5% improvement in sound. Not really worth spending any kind of money on. The DAC on my computer is fine, same with my iphone. Especially with the Koss budget headphones. It's recommended that you have an amp for heaphones that have an impedance of 50 ohms or higher. If its higher than 50 ohms you might want an amp just so the drivers are poperly driven, or it will sound real quiet. But test it first at full volume, you might not need it. If you do, there are Amp/DAC's in the $60 range that should do just fine. You definately don't need it with the KPH40's. So unless you can get it for free like I did (VERY nice friend), then I wouldn't bother with it. What about special cables? Not needed with the KPH40's alone. I had trouble with distortion running headphones from my amp using a cheap amazon 3.5mm extension cable, so I just got a USB extension cable instead and ran the headphones driectly from the amp. Problem solved. If your still having problems with distortion, there's guides online on how to make quality cables on the cheap. But you shouldn't need them. Please don't spend more than $20, the cost-to-sound improvement ratio is the worst here. OK, rant against the heaphone consumer industry over...and thank heaven for Koss! --- THE BOTTOM LINE - So for normal people (99.9% of the population), I recommend you forget the expensive monitor stuff and get the KPH-40's for the $40. :D Other than the modifications I mentioned, you can also use the Kramer Mod to further fine tune the sound profile, but I don't think it's necessary with the KPH40's. Guides for the Kramer Mod can be found online. LINKS TO STUFF I MENTIONED - Here's the YAXI pads I used on the Portapro's and the KPH40's https://www.amazon.com/gp/product/B01MQVHX84/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&th=1 Here's the Grado Pads I used on the KPH30i's https://www.amazon.com/gp/product/B00TGCDHL2/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1 Here's some painters tape for the Portapro's.

Since this review I have noticed that the Koss KPH40 headphones do tend to "bloom" in the upper-mid Bass range. What does that mean? There is a mildly loud reverberation when the Bass hits a certain frequency, and ONLY that frequency. As the sound gets lower the bloom goes away. For this reason I have gone back to my repaired Sennheiser PX-100 (originals) as my main headphone. But I still love these headphones!

Let's get to it then, shall we. I am an audiophile. Audiophile: a HiFi enthusiast. With that out of the way let's discuss these little gems. I can't stand (personally) the description of if a thing is good for it's price. Price may not be subjective but what a thing is worth in relation to how it sounds is subjective on a good day. Instead truthfully if a thing is good it's good, if it's worth it it's worth it. These my friend are good and worth it. At just a tick beneath the price of the Koss Porta Pro you get the KPH30 and it delivers. So let's look at what you get and what you should expect. 1. Koss' Limited Lifetime Warranty. It's broke, they fix it. Pretty straight forward and admirable considering the intended use of these guys. I'm pretty gentle on my stuff but one trip through Amazon reviews for earbuds and you'll quickly find out the number one reason most people go for a new set is 1. damage like one side no longer playing music and 2. people love to loose thier stuff. Nothing Koss' can do about number 2 but they've got you covered on number 1 so there's that. 2. A lightweight highly comfortable headphone in nice, clean, modern colors. None of that "hey, come steal me" appeal you get from some pricier fashion cans. If you let people listen to them then yeah, expect friends, family members and co-workers living that earbud life to totally swipe them. They're really quite good. 3. Practical usage. No, these aren't really for exercise or blasting music (at a desk anyway) as there will be sound leak. You can't use them to hide from your kids or ignore your spouse. But if you're jamming out to James Brown, Daft Punk or whatever your jam is snapping fingers and doing your step they do not fall off. I have a very large head. I honestly have never been to a Lids or New Era or Belk or something and found hats in store in my size. I always have to order. That being said, larger ears and all they stay on my head with no pressure, heat or discomfort. No "headband" markes on my head or hotspots. All day comfort. 4. Yeah I mean, they're plastic. So's your cars bumper so that doesn't mean it's cheap'o. The point is they're cheap but don't feel built to a price. The adjustment is easy and holds it's place. They don't squeak or creak or otherwise flop around or do things that ".99" dollar store headphones due, contrary to another person's review. 5. SOUND. All caps because that's the number one for most people. If like me, you've listened to lots of headphones, earbuds and in ear monitors you will understand that jumping from one particular sound to another can be jarring. These sound better than the Apple Earbud if that's your concern, the OG ones that end in 3.5, the lightning ones don't sound as good or the same as the old ones. These sound about like Sennheiser HD558's but with better bass presence. The highs are present, sounding more recessed than rolled off. It's not quite like they took away the highs but more like the pulled them back to be non-fatiguing. Bass is solid but not boomy. There's no mid-bass bloat. As a matter of fact the mids are very well positioned not quiet forward but the music, bass and vocals are equally the star in these. The details are there but not the focus, wich makes them well suited for jamming out or long listening sessions more so than critical listening They're warm. Bass is tight and with weight. The bass goes deep but not hi end sub-bass tremble sort of deep. I could keep spitting out descriptions off the top of my head but suffice to say, it's like the Sennheiser HD558, but more involved. It's a warm sound with highs tamed as to not be aggressive and fatiguing, still has detail, bass is good and solid enough to satisfy for rap, dub and edm but controlled enough and restrained enough to not interfere with the mids, male vocals or jazz. To me these are on point for jamming out at louder volumes, relaxed listening while reading, while working, loosing yourself in the music, and phone calls. No one could tell I was on a headset vs my phone without me specifically mentioning it. They're $30 and a hell of a lot better than your stock earbuds or some cheap $10 or $15 one over all. If you want more treble energy and a more in your face sound the Porta Pros are the better buy. But don't over think it like these are some super dark sounding phones. There's still more treble energy than V Modas or the HD598cs. Not comparing them, just saying if you want every box ticked from comfort to function to sound to being able to listen to them all day. These ARE outstanding. I bought these to have something that still sounds good to use with my LG V30 other than my in ear monitors. I wanted to be able to take calls and hear things around me. I also wanted to have an open air sound like earbuds (not in ears) and open back headphones give you. But in a tidy, easy to travel or store package. For when I'm cooking or washing dishes or cleaning or just reading my Kindle. I didn't want in your face great sound that's hard to deal with after an hour. I didn't want a saong and dance requirement to manage the cables or put them on and take them off. I didn't want to always have to hot pause to speak to someone. They met everyone of my desires with aplomb. Best of luck and I hope this was at least somewhat helpful in your purchase decision.

KPH30iCL Clear: Coming from someone who actually owned "retro headphones" like these in the 80s for my Off-brand "Walkman"...These have surprisingly good, full-range sound for the style of headphone they are. The bass is a bit boosted though, but most people prefer that. They do not interfere with wearing glasses. So there's that! Build quality is like a bunch of little chicks, "Cheap, cheap, cheap", but I think we all knew that from the photos. They look and feel like a $5 prison library loaner headset (don't ask how I know that), but sound like a $90 set. I do not recommend making a shank out of them though. The very good sound quality combined with the "bonus" built in microphone, makes them a good value...if...they will last longer than they feel like they will. They're on the small side. If you have a "tall" head or low ears, like me, you'll have these at max and still feel like you're stretching them a bit, which is unwanted leverage to make them easier to break, but they do fit, unless you're 'Joseph Merrick'. They have a good amount of clamp and weigh almost nothing, so they're not 'trying' to fall off. EDIT: 2+ years, still holding up with medium-occasional use, so they don't just fall apart too easily. Still sound ~great.

These sound stunning. They punch WAY above their price bracket in terms of clarity, technicality, tonal colour. The soundstaging is pretty eh.. they are open backs so I would not wear them on transport but they are SO light and they feel like nothing. They are on ear headphones so for me at least, after a while the clamping becomes quite unbearable especially because it pushes the ear onto my head and my it starts to hurt. I modded mine with the KOSS foam pads and I removed the foam from infront of the speaker unit and from inside the headphone and it improved clarity so much. it also helped just a little bit with soundstaging but not a lot. Overall an amazing headphone. The build quality is a bit budget but in my book thats actually a really good thing. It's light and when you fiddle around or try to mod it, you dont feel stressed you might break something. you can see where things are clipped and attached therefore you can see how you can open it up. New and premium headphones love to hide and glue and seal the seams and it just makes modding or repairing so much harder. These remind me of the days when music players were a dedicated device and the fact that they still sound so amazing is so nice.

This is a very light headset. This clear version is as close as we can get to a budget open back headphone. Easy to listen to. Great for both music and gaming.

Tout d'abord, je mets fin au suspense: ce casque est bien meilleur que le Porta Pro: scène sonore plus ample, grave profond, aigu doux et précis, bon rendement, moins de distorsion, il va plus loin que son illustre ancêtre et fatigue beaucoup moins. Il est neutre et musical! Le confort est excellent et il tient parfaitement sur la tête (je l'écoute beaucoup en marchant). De plus, il intègre le micro pour les appels vocaux. Beau look vintage (certes pas aussi beau que le porta Pro). Seul bémol, l'arceau est fragile sur les côtés (j'en ai cassé plusieurs).

Nada se le acerca en esta categoría de precio, el único inconveniente es el material ya que parecen auriculares de avión, pero la verdad por como suenan podrían ser mucho más incómodos y aún valdrían la pena.

Not the most technical headphones out there, but tonally they are just great. Open design, allows to hear outside (and outside to hear what you've got playing) but this is what i wanted. I use those mostly for PS5 gaming while sitting with kids so i can hear them, but frankly they are good enough to be used for music listening. Incredible sound. Very comfortable too: i can wear them for hours. Extremely easy to drive: i'm yet to encounter a device that couldn't drive them.
