It has been 2 days since I received these headphones.
Comfort: While at first the bands are a little tight, you can loosen by bending them slightly. The padding is amazing. I have worn these for hours without any discomfort.
Sound Quality: Nothing short of amazing. (I am not going to go very far into this, many reviews have described it much better than I could)
Compatibility: I am using a cheap amp that I also use for my mic, the Behringer U-Phoria UM2. This amp powers it more than I will need. For phone use, I use a S8, I think it powers it to just enough volume. I do not listen particularly loudly, but I still think the S8 powers it enough.
Case: It comes in very nice packaging, which could be used as a carrying case, kind of.
Gaming: So far, I have only used these on Rainbow 6. I've heard that these do not have enough bass for great performance. But so far, I do not agree. I hear footsteps and bullets, very clear.
Padding: Attracts a lot of dust. Not a really big con.
Cord: While it is detachable, and replaceable, I wish it came a little longer.
Hair: I have semi-long hair, and every once and a while, it will pull my hair out.
Sound Leak: These are Open Backs, so you can hear things around you, and things around you can hear your music. The amount that leaks out of these headphones is very minimal (At med-high volume, you have to be very close to hear it), but if you have a loud background, these will not stop sound from coming through.
Overall: Great pair of headphones for an amazing price. I think one of the best on the market at this price range.
