Superlux HD-668 B

I've owned several of these cheap Superlux headphone models. Some of them have sounded very impressive for the price. These ones... not so much. Perhaps I just prefer differently voiced headphones but these ones seemed a bit too stiff and sterile sounding to me, and still not neutral/detailed enough for mixing (which to be fair would be too much to ask at this price).

Comfort is slightly better than on the other Superlux headphones I've tried though. I prefer this headband design over the one they use on their even cheaper models. They are still very clammy with their all plastic design though.

Build quality... Seems ok but I know from experience that all these cheap Superlux headphones have VERY thin and fragile cables that always break, usually near the plug. And the plug is of the molded kind so it's impossible to re-solder it. They can be fixed at the cost of a new jack plug but the thin wire is a pain to work with and it WILL break again.

I got these just to have a couple of extra cheap headphones in my control room but would never consider them for hifi/critical listening or mixing. And obviously the open back design limits their application for tracking work. But just to have around the control room as an alternative monitoring for doing synth/MIDI overdubs... they are great!

Very nice for the money. They feel less cheap than the price but they still feel cheap.

I like to exercise bass playing using headphones when playing at home late in the evening. So far I did that with high end in-ears, which just sounds amazing. But - fumbling these headphones into my ears became cumbersome over time - I hoped having some over the ears phones I could just cramp on my head and start playing might be easier to use. Reading several reviews about which headphone to use for bass playing I found a lot recommendations for this one, and given the price is stunning low I ordered them.

When they arrived I did a first quick test by listening to some bass biased music - Marcus Miller, Victor Wooten etc. I found the sound quite OK, but not as impressive as reported in some reviews. Very good given the low price, but far from excellent.

Then I plugged them into my bass amp and tried them with my bass. Too bad - my bass sounds as dull over these phones as it always does when I use anything else than my in-ears.

So - if you want to listen to some pop music these phones offer decent quality for a very low price. For Jazz or anything where you want a neutral tone and transparent heights they or not the best choice - but hey, they cost almost nothing!

Bass players can use them for exercising. If you are up for a more vintage tone he will probably like these phones, especially if you use flat wounds. If you prefer clean or even brilliant sounds you need to invest more money.

As the title and scores suggest, these cans are not comfortable and this is a huge deal breaker for me. And this is the reason I'm returning these.

The problem is that no matter how I adjust the wings, the plastic headband just digs into my skull. The problem seems to be that the headband is just not large enough.

Such a pity because the sound that is coming from these is pretty good. The highs are not unbearable like in the 681s, the bass is astonishing for the price, the mids are slightly recessed, which I don't like but it's not a deal breaker for me.

The stock ear pads are crap so they need to be replaced.

But what I highly recommend you do is to get the Samson SR850. Supposedly, it's made by Superlux and is a copy of the 668b. But a lot more comfortable because it has the AKG style head band and velour ear pads (at least some of them).

I bought these for use as a gaming headset. Overall, for the money they are perfectly adequate. Sound quality is fine, not too heavy, build quality is fine.

My issue is that they are very very tight. I don't have a particularly big head (I take a size small in motorcycle helmet). They are fine for an hour or so but any longer than that and they become very uncomfortable. I've tried to stretch the headband out by leaving it on the back of the chair overnight etc but to no avail as it just springs back into place. I've had to spend the money again on a different set.

If you're on a budget and only need them for an hour at a time then go for it, any longer than an hour I'd give them a miss.
