The best headphones aren't perfect. In fact, I doubt that any company will ever make a set that are entirely without flaws. That's not because one of them does anything wrong per se, but mostly due to the fact that everyone's taste is different. Even when you find a set you really like, you probably wish there was a little more bass or a little less treble or you had the ability to manually tweak the EQ in a way that made a noticeable difference. Companies like Sony, Jabra, Sennbeiser and many more have apps that allow you to make adjustments, but even then, if you're like me, you still want more.
