Product Description
The HD668B is a semi-open dynamic headphone whose sound quality meets the demands of even professional recording studios. Its patented sturdy construction provides long-lasting durability even in challenging conditions, yet the headband’s light weight and optimized mechanical pressure provides long-term wearing comfort.

Both cables can be connected together for even more distance if desired.

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.

Initial Impressions:
Let me say, out of the box, these things do not look, nor feel, like a quality item. There is literally no heft to them, so I was a bit suspicious. I put them on my head, and surprisingly, they are very comfortable, with just a slit head clamping, but a very secure fit. The headband, although goofy looking, feels very nice on top of my head. It is nice to have a pair of headphones that do not dig into the top of your head. I can see this headband design being especially comfortable for those that have longer hair.
The SuperLux come with 2 cables that are 3.5mm extension cables. The termination out of the headphones is a 3.5mm male connector. One roughly 3 feet, one roughly 10 feet. Both cables seem to be nice quality with a nice heft to them. Terminations look very nicely done.
Initial Listening:
I plugged in the SuperLux into my Oppo HA-2SE dac/amp. I am a very big fan of ESS Sabre DACs, so this seemed like a great place to start.
First up: Pat Metheny: Cherish. The upper strings of Pat's guitar ring through crystal clear, and the notes of the upright bass are present and full. You can hear Pat's hand sliding up and down the strings and the little buzz that happens when moving up and down the fret. The sound stage was big, open and very full. I had to take off the headphones and look at them for a second while murmuring "These cost $40?". I was literally blown away. So it handles Jazz well. How about Prog Metal with more complexity?
Next Up: Animals as Leaders: Physical Education. This is a very complex song with a lot going on. The SuperLux kept up with the heavy guitar riffs, bass guitar, and drums, all while sounding very full, all the while keeping up without being strained. You could clearly articulate all of the nuiances of the track, almost as well as my HD650s, which is quite impressive, and these are not even broken in yet for an hour.
Closing:
I bought these on a whim since I wanted something new to play with. Give them a chance. You will be honestly be surprised what is coming out that is not a 'name brand', and how fabulous they sound. Longevity is in question with all of the plastic, but for $40, you could buy a new pair every year and still it would be a good value.
Cheers!
**EDIT** After a using this for roughly we a week, the sound really has opened up, and the mids are much more present, and the brightness has tamed. I find that the cans could use a small EQ tweak at the top end of -2dB, which seems to just smooth out the sound signature.
I also found the stock pads a little uncomfortable for long term wear and quite warm, so I purchased a fairly inexpense pair of Cosmos pads, which are a velour pad, that fits perfectly on this item with little to no stretching of the pads before installing them on the cans. I noticed little change to the sound signature, just a minor reduction in the bass, but perfectly clear highs and mids. The increase for long session wear alone was worth the upgrade. The replacement pads can be found here: https://www.amazon.com/gp/product/B00KLPRQMO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 **

despite this, they still end up breaking at the same spot every time, the wire from the headset will come loose over time and being to expose the inner wire, even using the bracket to stop accidentally disconnecting them will not help
you will lose audio in one ear completely, or it will end up sounding very echoey and tinny.
now, onto the actual quality:
first off, these are an EXCELLENT intro to high quality audio, with a high quality audio source, you won't want to listen to anything else. I'm not too well versed on quality audio, nor am I an audiophile, but the sound quality of these paired with any good on-board motherboard sound the difference is night and day compared to any generic gaming headset.
pros: great sound
good for the price
works well with most devices, (low power needed)
cons: semi decent build quality, the earcups are somewhat comfortable and fit your ears nicely, and the headband somewhat has comfortability, though they weren't suitable for long periods of time, often i'd come off with headaches as they would press into my glasses and ears, making them go extremely numb
overall, I just can't recommend these, every time they break, without fail, no matter how much I baby them.

Okay, enough of the high-falutin' probabilities.
These Superlux HD668B headphones are, I imagine, a serious attempt to rival the normally mid-to-high-end Audio-Technica ATH-AD series of headphones.
As a 79 year old, I now have to accept that my hearing capabilities are not as sensitive (especially among the higher/upper frequencies) as they were when I was told I had 'pitch-perfect hearing' albeit when I was a 20+year old....
Today, I am unable to determine/perceive which (from among the Superlux HD668B and several of my Audio-Technica ATH-AD series) reign supreme. All produce very similar high quality sounds that are very close to the original performance when connected to quality audio reproducing players and amps.
The only real difference which I (and probably most other audio enthusiasts will be aware of) is the "comfort factor".
These Superlux headphones are, in my opinion, of a better design and fit than almost any others of a similar price. However, I have given only 4 stars as the brilliantly performing 5 star "audio performance" is let down slightly due to the reduced comfort level...especially when being used for several continuous hours.
When or if there was just a tiny-but-extra-bit of "give" or flexibility in the way they fitted my awkwardly shaped large-sized head, they would have merited 5 marks "all the way"...and with a warning to all the respected, established quality manufacturers, that they should 'look-out, there's real competition out there...and at a price that can only mean that a price-war between the budget and the established big names has now unofficially been declared!
Firstly Sound Stage is phenomenal, the spatiality of the sounds is both wide and deep. Despite having such great soundstage the imaging within the stage is really good. A trade off for a wide sound stage is sometimes being able to locate where a sound is coming from in that soundstage, not with these headphones.
The base response is very good with a good mid and high frequency range, the highs although high are never sibilant and as a result you can enjoy hours of use with fatiguing your ears.
One of the best use cases for these headphones is gaming as it will give you a competitive advantage as to where ads are, especially when playing PVP, again this is because of the wide soundstage. These headphones are also fantastic listening to lossless music paired with an Dac or Amp I have used the Ican Micro Amp or Black Label Nano Dac and had amazing results.
One downside is that the earpads are a little uncomfortable so I swapped these outs with some from Amazon which solved the issue.
Summary
Buy them now and enjoy them, best headphone under £100 on the planet.
