These headphones costs very little, and it is quite apparent in the sound-quality. The bass is very prominent, mids are lacking, Highs are correctly placed.
The high end is actually not bad, it is there, does its job and does not hurt, which is very good.
The midrange is so low i kind of find it hard to hear the lyrics of songs, which, for me, does not bother too much as i mostly use these for DJ-mixes and find that the lyrics is less important in those scenarios.
As for the Bass: There is a lot of it. Too much. When the listening experience turns in to KICK and BASS only whilst i'm not listening to Techno, something is very wrong.
In these headphones all you can hear is KICK, which does not bother me as i only use these for DJ-Ing, and do not really need more than that. If you are thinking of buying these for listening to your favourite songs or for any use where you want good sound, buy something else.
All that being said, I am not dissapointed in my purchase, you get what you pay for, and they work for me.
