## Overview

The Superlux HD668B semi-open studio headphones deliver professional-grade precision with 50mm neodymium drivers and a wide 10–30kHz frequency range. Designed for critical monitoring, their semi-open architecture provides superior imaging and separation, making them ideal for mixing and post-production.

## Description

The Superlux HD668B is a semi-open reference monitor headphone designed to be revealing and precise for studio work. Its detailed presentation helps you identify mix issues quickly—useful for editing, EQ decisions, de-essing checks, and verifying ambience and separation. With Ø50 mm neodymium drivers and a wide 10–30,000 Hz response, HD668B highlights transients and fine texture, making it a reliable tool for mix-checking vocals, cymbals, and instrument definition. The semi-open design assists with imaging and separation, supporting placement and depth judgments in complex sessions. Built for long use, it features a lightweight frame with an auto-adjusting headband. For practical workflows, it includes detachable single-sided cables in 1 m and 3 m lengths plus a cable clip to reduce accidental disconnects. Listening note: HD668B is intentionally revealing; on bright tracks or bright systems, the upper mids/treble can feel forward—many users like it for analysis, and some apply slight EQ for casual listening.

Review: Best value in headphones - So these may not be a giant killer, but they are something special. At <$50, these represent a stunning achievement in terms of quality. This is a price that makes this a giftable headphone if you want to introduce someone to the world of good audio. I bought these on a bit of a whim, but it was an amazing decision. So first of all, these are still $50 headphones, so a few things were compromised, but not too poorly. The packaging is rather plain, but effective. It has a semi-retro look to it, which I find somewhat appealing even if it is bland. Included with the headphones are two detachable cables (3.5mm), 3ft. and 10ft. respectively. There is also the ubiquitous 1/4" adapter. Everything is gold plated. Right away, I give many extra points to the inclusion of detachable cables on a cheap headphone. I had read of others saying that the cables were flimsy or transmitted static. I have experience no static and the cables seem quite robust to me (thicker than the usb cable on my mouse or keyboard). The headphones are (IMO) quite unattractive. They are quite obviously cheap plastic when you hold them, and even the ear pads have a decidedly cheap look, even for vinyl. Complaints aside, I can bend and sway the headphones without fear of breaking them, and feel pretty solidly built, and I'm sure they can survive a few drops and dings. Comfort is hugely important to me, because I wear headphones all day long. These are the MOST comfortable headphones ever, but they are better than other reviewers would have led me to believe. They utilize a wing system like audiotechnica. I have had other cans that I felt like I needed to take off from time to time or reposition due to discomfort. So far this is not an issue with these. Having said that, you won't ever forget that you have them on either. I will also note that I wear reasonably thick framed glasses, and which they do exert some pressure on the frames, it is not enough to cause discomfort. It is still winter, but I can tell that in the summer, my ears will sweat from the vinyl ear pads. I may upgrade to velour as winter passes. I have heard others say that the wings press to much into their head. Again, this seems like a very minor complaint to me, and is the least noticeable aspect of the headphone interaction for me. I have only just received these (no burn in, etc.) but they sound great. The sound is EXTREMELY clean, almost to a fault it feels at times. These are a colder sounding headphone for sure, very much precise and analytical. The bass is present, and a bit warmer, but never anything remotely punchy, I only listen to a small amount of electronic music, and it handles it reasonable well, but if it was my primary genre, I might start looking elsewhere. The mids are perfect, everything is fantastically clear, and I am hearing things in songs I have never even heard before. The highs...can be a bit much. They are extremely clear, the headphones don't strain to reach their greatest heights, but they are a bit overpowering. I recommend anyone with an EQ try lowering 7-10k by 2-3db and 10k+ by 3-4 db to make it more palatable. This is especially true for electronic music. the synth sounds actually approach painful levels at times. Surprisingly good soundstage, especially with older music (as always), but the semi-openess actually leaks fairly little sound, and I don't see these levels of leaking really bothering anyone (namely my wife about 5 feet away). I never review products, but I am really impressed by these. Best headphones for the money, easily.
Review: Best I have ever used under $60 - Probably the best pair of headphones I have ever used for $40. there's a pretty good amount of bass that won't please audiophiles, but for gaming or basic music listening for this price, can't be beat. The mids are very well balanced and is clear, as is treble. They sound AMAZING for the money. Another thing about them being semi-open headphones: they have a dampener. While they feature all the quality of open back headphones, they don't bleed sound to the point where other people 10 feet away from you can hear your music. The headbands do feel plasticy, even though they're soft, so if you're a guy who wears his hair completely shaved, or you've already lost your hair on top, these might cause some discomfort. The reason I put 4 stars instead of 5: the earcups are awful. They're faux leather and make your head sweat 30-40 minutes after you put them on, even in winter. Get some fabric or velour pads. Here are the ones I bought that fit this headset perfectly, and they make the headset 100% more comfortable: http://www.desertcart.com/gp/product/B00KLPRQMO?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 These are very light and ergonomic. They do squeeze my head slightly, but after I swapped out the stock earcups with fabric ones, the feeling went away, and became more of a "firm grip" that the headphones really need so they don't fall off. The only other gripe I have is the 3.5 mm connector which is on the headphones, instead of using a male-male cable to connect your device to the headphones. Headphone companies: cut this out. I recommend these 110%. If you're a PC gamer on a budget, or if you want a good listening experience under $60, you cannot go wrong here.

## Features

- Reference Tuning for Precise Mix Decisions: Built for critical monitoring—helps you judge level balance, EQ moves, edits, and noise more confidently during recording, mixing, and post-production.
- Imaging & Separation for Placement Checks: Semi-open design supports clearer left-right placement and layer separation, making it easier to evaluate panning, reverb/room cues, and depth in a mix.
- 50mm Neodymium Drivers (10–30kHz) Reveal Detail: Wide response and fast transient presentation help uncover sibilance, harshness, cymbal texture, and subtle artifacts that can be missed on more “forgiving” headphones.
- Revealing Clarity (Listening Note): Purposefully detailed for analysis and mix-checking. Listening note: on already-bright material, the upper mids/treble may sound forward—some users prefer a warmer chain or slight EQ.
- Lightweight Comfort + Detachable Single-Sided Cables: Auto-adjusting headband for long sessions. Includes detachable straight cables (1 m & 3 m) and a cable clip for flexible studio and desk setups.

## Questions & Answers

**Q: how are these vs the  sentey arches gaming headset headphones usb 2.0 connector 7.1 digital surround sound (white) gs-4731**
A: The problem with USB headphones is that they're just headphones with their own USB audio sound card.  Most onboard audio already provides virtual surround sound.  If they don't Windows10 offers Spatial sound for free, which will provide virtual surround sound.    I've been using these headphones with a ModMic5 for about a year now and they've been amazing for gaming.

**Q: What is the sensitivity (dB/mW) of these headphones? Can my laptop computer drive them?**
A: These are the specs direct from their website.  From my own personal experience, my laptop does just fine.  I have not amped them personally, but I have read (online) that they do improve with amping.  Also driving them from my iTouch is good.  Just switch off the EQ and they sound great.Type: Dynamic, semi-openDriver: ¨ª50 mm, neodymiumSensitivity: 98 dB SPL (1 mW)Frequency Response: 10-30,000 HzMax. Input Power: 300 mWRated Impedance: 56 ¥Ø (Copper-coated aluminum wire)

**Q: As Semi-Open headphones, will people around you be able to hear what you are listening to? Also, will a headphone amp increase the sound quality?**
A: To piggy-back off Seth's answer, I have these and Audio Technica models m40fs and ath-a550z, and both isolate sound more.  I can't hear my partner talking if I'm listening to music with those, but I can tell that she's talking to me when I'm wearing the HD668B.  She has also commented on how loud I listen to music while wearing them, though not with my audio-technica models.

Perhaps something others can relate to, I've tried to convince myself to give away some of my headphones (in part to justify buying new ones) but cannot make myself give these up.  They serve a purpose and provide a good listening experience.  My other headphones do to.  I can't say they are better or worse overall, but that it's a different experience which you may find more useful in certain situations.  And for the price, every audiophile should own a pair.  I'm about to replace the cable on these with a permanent one after the rubber near the ear-piece cracked.  No loss of fidelity yet, and I repaired it with shrink-wrap, but considering the price I'm using these as my first experiment to upgrade a headphone cable.

**Q: Do they come with the extra velour pads, like the HD661s?**
A: I just found the perfect set at amazon.com lyxpro has-30 replacement pads. $10.00 leather. Very soft and slightly deeper.Carefully stretch and roll edge over pad,put on diaphragm and roll on. May need extra set of hands. Takes patience,but worth it. So comfortable.Improves siblance highswith punchier bass. Sound stage and placement remains awesome.

### ⭐⭐⭐⭐⭐ Hear your music in all its glory!
*by D***Y on August 4, 2016*

The headphone/earphone competition today is fierce. The quest to offer better sound quality has been heating up since the introduction of the iPod and subsequent DAPs (digital audio players). Back then, the "pay more money for more performance" was the mindset. $20 headphones sounded like $20 headphones. $200 headphones put $20 headphones to shame, $500 headphones were better than $200 headphones and so on. The educated consumer knows that those days, for the most part, are behind us. It isn't that a $30 headphone can run all over a $200 headphone. No! However, the landscape and the game has changed considerably over the years. The competition is so stiff that you no longer have to pay lofty prices to get RELATIVELY comparable sound. The consumer that does his/her due diligence will discover that OEMs (Original Equipment Manufacturers) release headphones that are near identical to the big brand names but only have a slight variation in sound signature. A good example of this, seven or eight years ago would have been the Sennheiser CX300 ($40 big brand) versus the Creative EP-630 ($20 bargain brand). Today you might look at the AKG 240. Over the years, prices for the AKG 240 have gone from approximately $150 to $60+/- due to competition from the Superlux 668B ($38) and/or Samson SR850 ($50). The AKGs are in a completely different price bracket now because the Superlux and Samson are comparable at their respective price points. Question: Can a $60 headphone sound as good as a $150 headphone. Apparently, yes, because it is in fact the same headphone (AKG @ $150 = AKG @ $60). The difference isn't the sound quality, but rather the price point. This begs the age old question when it comes to audio equipment. Is the difference in price an exercise in futility due to the law of diminishing returns? In the larger scheme, no, but as the landscape changes, sometimes the answer is a resounding yes. I can list half a dozen sub-$200 headphones that will run roughshod over some very popular $400 - $500 headphones. The SoundMAGIC HP150 come to mind. What about the sub-$100 market? The Philips SHP9500 come to mind. They easily hold their own when compared to some very popular $300 - $400 headphones. Implementation and tuning is the name of the game and some of the well known brands fail to impress and their lofty prices are not justified. The uneducated consumer is simply overpaying for a recognizable brand. That can't go on for much longer. Indeed, the sound quality gap among mid-fi headphones has narrowed considerably and pricepoint may not be the reliable litmus test that it once was for the simple. What about the sub-$50 headphone market? Is there any reason to venture where only the entry-level sub-par headphones or the basic "two cans with a wire" usually reside? Is there anything remotely redeemable at this price point? clouds open and angels do somersaults.... It's the Superlux 668B. back to reality.... I bought these six months ago and have given them time to break in. What a great set of headphones these are. I can't say at any price point because these are made mostly of plastic and the earpads are entry-level. However, the combination of highly detailed, accurate sound and detachable cables for $38 make these a rare treat. How is it that $38 can gain you an above average set of studio monitors? Yes, studio monitors so you can hear the tiniest detail across the entire frequency range when doing a final mixdown. I think the lower mids are ever so slightly recessed in order to avoid bass bleed into the mid frequencies, but the lower-mid slight recess is barely noticeable. The lower-mids is where the warmth of a vocalists voice is, but again, it's barely noticeable. In general, you will hear everything the way the recording engineers intended for you to hear it. That is typical of studio monitors. These are phenomenal for $38, because you will hear everything. I should note that these go to the Nth degree to capture the details in the treble so if you have an aversion to treble you can always use your EQ to roll it off. These are all about the details. Treble extension is about as far as you can take it without being sibilant. I highly recommend these as studio monitors and if you enjoy a neutral sound signature these may work well as your go-to headphones. The detachable cable is such a nice touch on these because you can always replace the cable with a standard 3.5mm to 3.5mm cable of any length if it fails. You actually get two detachable cables. There is a 3ft 3in cable for mobile use and a 9ft 10in cable for home use. If you are like me and need more than ten feet you can simply combine the two cables for a total of more than twelve feet. That's great because I didn't have to purchase an extra cable to meet my needs. When I purchased these 668b headphones I purchased a set of velour earpads just in case the pleather pads made my ears sweat, but thus far I haven't had to install them. The doo-hickeys near the top, where you usually find a headband, are comfortable. The headphones adjust well for me and I have had no issues with fit or discomfort when wearing these for hours on end. Your experience may be different if you have a large noggin' or if your body temperature tends to run hot (meaning if you sweat easily). Bottom line is these are a "no brainer" at $38 because they are excellent. Easy decision. No regrets I'll post pictures at a later date. Hope this was helpful.
