Linsoul QKZ x HBB 10mm Titanium-Coated Diaphragm HiFi in-Ear Monitor Earphones with Semi-Open Cavity, Detachable Recessed 2Pin Silver-Plated Cable, Noise Canceling for Audiophile(with Mic)

I can't believe it took me 3 1/2 years to review these IEM's. I bought these in October of 2022 on my son's recommendation. He bought a pair a few weeks earlier and was floored by the quality of the sound for around $22. His are long gone (the housing broke in two after several drops). Mine, however, live on. I have tried many headphones, earbuds, and IEMs over the last 3 1/2 years, but I keep coming back to these for the incredible sound for the price. Even if these break annually, it would have been much better to buy three or four of these than any headphone or IEM costing the price of three or four Linsoul QKZ x HBB's. These are no longer being made, but my research reveals a couple of budget options that may actually be better. The $25 Linsoul 7Hz x Crinacle Zero:2 is supposed to have cleaner mids, more controlled bass, and more consistent quality control (something my son will appreciate). In the same price range is the KZ/CCA Castor Pro. It is supposed to match the energy and slam of the QKZ x HBB.

I've bought these twice. The sound is great, but the build quality is not. The female connectors on the iems break off after some wearings. I was going to buy a third pair because they are so cheap but I don't feel like buying these over and over because of bad build quality. If it wasnt for the build quality, i wouldve gave it 5 stars. but since its so cheap, its a no brainer buy.

I bought it for fun and use at the gym and throw it away. Surprisingly good built quality. Fits great, comfortable and comes with cheap light cord that never draws attention to itself. But the music sound like somebody put a huge blanket over the unit. It's stock tuning is very flat and balanced, but very veil and not much details or separations. Also has too much boomy mid bass dialed in, but you can also hear big deep bass somewhere waiting to be released. Spent a few hours with an equalizer and tuned the heck out of it using my awesome AKG N5005 as a reference and now this cheap $20 unit sounds better than IEM costing $500 or more. Tons of huge thundering sub base that never bleeds into the mids, smooth vocals and soso highs because I didn't have access to a good equalizer. Try as I did, but couldnt get instrument separations to match the Akg or my Ananda headphone, but with the huge clean sub bass adding more dimensions to music, the extra spaciousness is not missed. It sounds amazing now, very satisfying to listen to for hours. This unit maybe cheap, but it came with all the right internals to be a really great IEM built in. It's true potential is just waiting to be brought out. Its like Dr. Banner changing to the Hulk. However, to enjoy this awesome sound, you have to play all your music while under equalization. If you just plug it into any device without equalizer or any ap like Spotify and others that don't have a good equalizer. This unit will fall flat and sound like the $20 pos it was tuned from the factory and you won't like it. If you want something that sound much better than these right of the box and spend less without resorting to equalization. Get the AKG iem that came free on samsung phones from a few years ago. Amazon and eBay has them for only $12. Make sure they're the genuine units and not the knock offs.

I've got experience with a variety of budget IEMs and entry-level audiophile headphones, but my rating is based on using these purely for gaming. If you're looking for a great pair of IEMs that will deliver accurate audio where it matters (FPS games especially), you'd be hard-pressed to find much better in this price bracket, or even several times more expensive. The bass is present enough to be enjoyable but doesn't drown out important details. Mids and highs are very smooth. I don't find these to cause any sort of ear fatigue, even playing games with them in for hours. These excel at being able to pick up audio cues accurately, both in terms of direction and distance from you. I have a pair of SHP-9500s that I use for gaming, and for these being a single driver IEM, they manage to deliver a similar experience in terms of details, with a soundstage that is only slightly narrower, while being more enjoyable to game with because the frequency curve is free of shrill highs. Super impressive considering these are a budget pair of IEMs. My only complaint is that the earbud tips that come with it aren't super comfortable, but I'm not going to knock a star off for that when it's just my personal preference.

While these sound good, especially for the price, they lack a lot in design, size, comfort, and durability. With minimal use, the right earbud case popped open, and I had to continuously closed them when putting them on. This made the alright comfort much worse, and they did not fit well to my ear.

Bought this once, and the right earbud went out. Returned it to get a replacement pair and now that pair's right earbud has gone out. The earbuds are great in terms of fit because the earbuds stay in and the ear hook makes them snug, audio clarity is great and cord length is pretty good but having the same earbud go out twice is not a coincidence. In my opinion. Really disappointed too because for the price everything is great about them but they just aren't reliable.

These sound awesome, 12/10 I highly recommend these. I just got into the IEM world after being in the car audio world for a decade. The only buds I have that I love equally are my Galaxy Buds Pro with a Samsung phone for the higher quality Bluetooth codec Samsung Scalable Codec. I think these IEMs have better audio quality than my buds but it's really hard to beat the convenience of totally wireless Bluetooth with active noise cancelation and transparent modes. Even with the convenience my buds offer, I still love these IEMs just as much. They have the warmer tune bass I crave and overall sound fantastic. I will say they sound significantly better with a Qudelix 5K DAC AMP vs the USB C to 3.5mm 32bit 384K adapter I have. Part of that is my adapter doesn't provide much power so the Q 5K blows my adapter out of the water in terms of bass since bass requires more power. Even without adjusting the EQ curve I'm blown away. With the Q 5K there's a profile for these IEMs to level out the curve but I think they sound great as is. The one thing that needs changed is the cable. I got a linsoul 2.5mm balanced recessed 2 pin purple cable that is much higher quality. Cables won't make much difference in audio quality, but it certainly feels much nicer, plus going with a balanced 2.5mm cable I can push more power and it is a bit cleaner than the standard 3.5mm unbalanced. The in-line Microphone: The mic is alright in terms of quality, but it really needs to be clipped to your shirt or collar to be close to your mouth so the mic picks up your voice. If it's just hanging down then the mic barely picks up my voice and it's like I'm far away. The convenience of the mic though is handy so as long as it's clipped by your mouth you should be alright. Overall the only thing I'd change is get a balanced cable and then get yourself a decent dac amp to truly experience these IEMs.

Update: Linsoul was extremely fast in contacting me and offering either a full refund or a replacement new product. It seems as though there was a mixup between labels at the warehouse. Customer service was very efficient and satisfactory. Product-wise, a solid pair of IEMs. I find the audio quality to be about equivalent to a set of wired Sony earbuds around the same price, but the shape and ear loop make them much more convenient and comfortable on the ear than traditional ones that simply dangle down. Warning: you may receive a pair of used buds that were not cleaned when you buy this product at full price! My first red flag was when the box opened and the contents were upside-down relative to the outside packaging, which is not normal for most packaging. Then the IEMs themselves had the plastic half-peeled off already and the inner box was dirty--both forgivable, they might've had a rough manufacturing process. Then I opened the earbud bag and out tumbled a pair of clearly used, oily tips with mystery white gunk on them. They are also the ones that I would've liked to use. Pictures show the used tips with a pair of (I believe) unused ones on the right--the difference is clear. If you aren't alright with shady practices such as offering used personal items (in my opinion, things that go inside of your ears are considered personal), then proceed with caution.

Compre este producto para probar unos iem por primera vez fuera de los típicos baratos que venían con los móviles. Buenos materiales y cómodos, con almohadillas de recambio, un problema que tenía con este tipo de auriculares es que se me caían constante mente, pero estos van perfectos, en cuanto a sonido algo que te puedes esperar de un producto con este precio nada espectacular pero bien, es cable no parece malo no que se vaya a romper con facilidad y con medida suficiente mente grande como ara no tener problemas. No son 5 estrellar porque no es algo sorpréndete pero en general es un buen producto y lo podría recomendar.

Everything they said about iem is thrue! Fantastisch clear sound, mega bass.

Received the IEM-s and was instantly surprised by the sound quality. Awesome clarity and directional sound for gaming. Unfortunately the quality control seems really bad because after a month of really light use (dad to a 3yo so I don’t get much me-time) one side doesn’t work anymore. The issue is not the cable, since the left side speaker works on both ends of the cable and the right side speaker doesn’t work on either cable. Occasionally when I unplug the right side like 20 times it starts working again for a few minutes and then stops again. Would have honestly given this IEM 5 stars rating, but unfortunately due to massive issues I can’t recomment it at all. Edit: Support was very eager to resolve the issues I had and they sent a replacement unit. Took a bit of time since the replacement had to be sent from China, but it arrived and everything works perfect now so far.

I bought these to try something different to my (now) old KZ ZSN PRO X, i must say, these QKZ X HBB iem are so much better than the Pro X. the bass is amazing and not too powerful that it overpowers the other instruments. The mids is perfect for me and the treble isn't harsh. Unlike the the Pro X that fatigued my ears these QKZ X HBB iems don't fatigue my ears at all. For the first time using iems that was tuned by HBB its pretty good. The design is amazing, i quite like colour and design choice that QKZ went with this. Overall this iem is amazing for £20 for my usage and paired with the Tripowin zonie cable for an extra £20, it looks soo much better than the stock cable + feels better and tangles less!
