First of all, above any other factor, these are just SO COMFORTABLE!! There are very expensive headphones I used that sound really good but feel like someone is trying to crush my head. These have really little(if any) clamping force that I forget that I have them on sometimes, but they are so well designed and tailored that they don't fall off even when I'm doing a headbang.
The sound is really great but it might not be what you are looking for. It is pretty much a v shape. The bass, as mentioned, is more than usual but it is very very rich and articulated (not to be confused with beats bass). The highs could be dry for some poor records but with the right source you get a smooth and airy treble. The mids is not its best range but it is decently articulated. It does not position instruments as well as some open back headphones but with the right source the mids will not sound messed up. After all, these are portable headphones that look really cool but you can definitely get a good sound out if it with the right source, even with your phone.

First of all, fantastic sound. Not necessarily *non-biased*, but possesses smooth highs, fantastically defined mids, and rich, powerful, yet completely not overwhelming bass. I accidentally broke my pair(which is completely my fault) and I sent them an email about it, and they sent me a replacement that is brand new. If you're new to hifi, and want a pair of versatile in-ears, these are definitely not letting you down.
