They're my favorite audio thing ever. The best mids and vocals you'll find, along with enjoyable bass and mid bass for an open back. Treble is there but smooth, making them very easy and relaxing to listen to. They have an intimate sound stage, but I prefer that. They play just about everything well. I mostly listen to Heavy Metal, and the 6XXs are really fun to listen to it with. They can be used to chill with, and head bang to energetic music.

Comfort is another level. At first I hated the HD 6XXs, cause they had a head crushing clamp. Once I carefully bent the metal part of the headband, they perfectly sit on my head. I can wear them for 8 hours without any fatigue. Helps that they are very lightweight too.

They aren't built with premium feeling materials, and don't have the looks of Meze products, but they're still built to last.
