Good sound, poor comfort and quality
Varu, 15.10.2019
Bought them long time ago for mixing/producing. Sounded good, clear, however the comfort was horrid, huge pressure on ears, pain was imminent using these, also, with original pleather pads these were really sweaty thing to use.
Poor build quality as far as cable connector quality comes - cable that runs from headphones to connector went bad after a while, no easy way to fix this other than removing their cable connector assembly completely and resoldering new cable inside the headphones thus making cable permanent.

+cheap
+said to be rather neutral
+rather good sound stage, ie, don’t sound compressed
+extra cables and carrying pouch included(one of the seams disintegrated rather quickly tho)

-poor build quality, cable that goes from headphones to 3.5mm female plug broke down very easily
-hot on ears, gets them sweaty
-very, very tight, not recommended for longer sessions, otherwise ear pain guaranteed, so you might want to put these on some kind of stretcher or something, to easen up their clamping force

OK for the price
Frank6282, 16.04.2015
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.

Slightly disappointing compared to other Superlux headphones.
TrEr, 29.05.2017
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.

Great value!
christof54321, 05.09.2019
Bang for buck, these are excellent headphones for students.

Reasonably comfortable.

Sound quality is great! A little bright sound at first, but this settles after a bit of use.

Build quality is moderate. They're not tough, but not fragile either.

I would buy these again and again at this price.
