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. The HD668B comes equipped with 2 detachable straight cables: the short one is 1 meter long for personal sound source on-the-move applications and the long one is 3 meters long for professional monitoring applications. Both cables can be connected together for even more distance if desired.

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.

A review from another happy owner and DnD and techno producer. So I will judge the headphones from the producer's perspective, not from the "average consumer" or "hifi enthusiast" perspective.

I have several years of experience in electronic music production. What I have learned over the years is that you cannot mix on headphones, no matter how good they are or supposed to be. Headphones will never give you a good overall picture of your mix, they will be always misleading when it comes to the overall stereo image and overall balance of the mix. This is physics which cannot be fooled by any marketing trick or belief.

BUT, headphones are very good when creating your own sounds using synthesizers because they can give you a very detailed picture of the particular sound, where it belongs frequency wise and what the problematic parts are. Sound created on synth using headphones should sound similar (in ideal case the same) on your monitors. So headphones are rather a surgeon's analytical tool for pickling up subtle inaccuracies in the mix then universal tool for making good overall mixes.

Taking the above into account what can I say about these headphones?:-)

The bass response is the story for itself. They have an exceptionally good bass response. Yes the bass IS hyped a bit, but it is very detailed and tight If you know what I mean. No blurred picture of the bass, little overloaded (so what? Don't forget you have your monitors for the overall balance!!), yes, but very, very precise.

These speakers do not sound "forward" as other headphones with hyped mids. Mids on these are accurate and not overloaded.

So far, I'm going with 4 stars; it won't take long to upgrade this to five stars if it continues to perform as well as it did immediately upon receipt.

I had the following concerns based on the Amazon and the Head-Fi reviews:
1) That the highs would be too high--possibly even sibilant.
2) That the fit would be uncomfortable (too tight; too warm).
3) That the build quality would be poor.

So far, all of those concerns have proven to be unfounded. I'm not a sound-expert, but on a quick listen to a range of music (Bill Evans on the piano, Justice, etc), I found the sound to be well-balanced, enjoyable, and clear. Neither the highs, mids, nor lows were overwhelming. On the second concern, I have a large head, and these fit well, with no pinch. In fact, I wouldn't mind a little tighter fit. I also have large ears, and the cups covered my ears entirely. Finally, the build quality is fine. It's not bullet-proof, but it's solid enough for this price range.

I'll continue to listen, and if they sound much better after about 100 hours if listening time, I'll come back to upgrade the rating.

I thought it prudent to give the headphones some time before posting a review. So I did, and my opinion has only gotten better. Owing to the semi-openness, the soundstage is pretty wide and the pressure on the eardrums is reduced. Downside is that it leaks quite a bit of noise. I use these at work so I have to use my Sennheiser HD419's (closed) when I feel like cranking up the volume. I also use A Behringer UCA202 dac and HA400 headphone amp which gives me a slight improvement over the onboard sound from my work computer.

Things I Like:
The sound clarity is amazing. I can clearly separate instruments in almost every track.
Voice and instrument sound reproduction is very accurate.
Wide soundstage.
Comfortable and lightweight headband.
Detachable long and short cables.

Not so good:
Pretty unforgiving. If you are trying to listen to some streaming music with not so good quality these headphones make them sound worse.
Highs are too sharp and base is a bit lacking. Even after giving it time, the highs can be a bit too much and starts hurting my ears.
Not a flat response.

Overcoming the downsides:
The first thing I did was replace the pleather ear pads with soft ones I found on ebay. Makes a world of difference when you wear them 8 hours a day.
To address the harsh highs, I replaced the fabric in front of the driver with 5mm foam. This not only made the highs less harsh but also improved the lower end.
These cans also benefit greatly by some equalizing. Turn down the highs a bit and bring the base end up and they are perfect.

I also have a pair of ATH AD500 that I use for gaming but prefer the 668B's for music.

I highly recommend these for someone looking to get high quality sound on a tight budget.
