Behringer HPS3000

I bought these headphones to exclusively use them for recording vocals and instruments. I already had good closed back headphones (AT M50x) for when I record my own, but I wanted another pair that could be used by my collaborators, who come to record in my small studio. Since I'm not really making good money with this activity, I also wanted to avoid investing too much in a pair of headphones that will be used intensively and therefore might break rather fast.
These headphones do a great job as long as you don't need very high volume while recording (vocals for example). They isolate the sound well, without problematic sound leaking at low to moderate volumes. At high volumes there will be leaking, but this applies to most of closed back headphones, even in the high price range.
Their sound is better than I could have expected for a 12 euro pair of cans. The bass and treble are quite present and even if I prefer more neutral sounding headphones, my collaborators find this to be appealing while they record vocals. Still, their sound is far from good. I was just expecting worse from a 12 euro pair of headphones.
Sound isolation is weak, but not problematic. You will still hear what's happening around you while wearing these cans.
The build quality is (let's say) decent... Still, I've seen headphones with 2 or 3 times the price of these ones and the build quality was not much better. If the cable would have been a bit better, it would have been excellent, but it's not... it's very thin so you'll have to take care to avoid tangling. The headphones also came a bit "dirty". There was some sort of dust all over them, but after a good wipe they were alright.
Anyway, as these headphones were 12 euro, I am satisfied with the purchase. My collaborators use them in my small studio mostly for recording vocals and for a super cheap solution they do their job very well.
I'm curious how for how long they'll do their job, considering the fact that they are used moderately. I might come back and add more to this review, after they'll be in use for a few months.

The headphones are almost in the same condition as they were when they were new. They have NOT been heavily used, but they've been in use from the first day. Since Sonarworks updated their supported headphones list, there's now a profile for HPS300 available for their headphones edition of Reference 4 calibration software.
So far, I can tell that for this price, these cans are probably unbeatable.

Very good headphones for casual use, which means when you want to listen to something not more than 1 hour, and when sound quality is not crucial.
But, if you plan to use them for many hours, they will become quite tiresome to wear. Also, don't even think about some more critical usage such as mixing, recording etc. They are really not at that level.

But still, good choice for amateurs considering the price.

I ordered them for monitoring while recording in studio, as I don't need a high quality of sound for that. The feel quite comfortable, but the plastic they are made of feels quite cheap. The only real problem I encountered with them was quite short cable that cannot be disconnected, but I solved that with long adapter cables. When playing music really loud the bass starts to distort quite noticably. If you plan to use them just for monitoring and metronome playback while recording I would recommend them, as they are a cheap but useful option, but if you intend to do anything else, I would urge you to look elsewhere.
