Unbelievable sound quality for their price, they rival some 80 euro Shure headphones that I have. They have just the right amount of bass, not excessive that it overwhelms nor nonexistent, it's there and goes very low for bass lovers. The highs are effortless without piercing your ears. Overall, they have a warm and comfortable sound. I drive them with an Asus sound card for flac audio files, movies, games and I am completely satisfied.

They have average sound quality. The positive thing is that they are very comfortable and have good sound isolation. However, the left earphone broke after 3 months... In my opinion, they are not worth it.
