To start off, these aren't my cans. They were a gift to my brother and he wanted my to review them for him, and I must say that I am pleasantly surprised with this remake of the Hesh. I owned the previous model of the Hesh and they weren't great, but the Hesh 2.0 bring a pleasant SS similar to the DT770. Not the SAME SS, but it has that U-shaped sound curve the Beyer's are famous for.
In terms of sound quality, the 2.0's deliver a wonderful bass response, with decent bass extension. Not as deep as some may like, but the mid-bass has enough UNF to satisfy bassheads IMO.
Mids are slightly recessed, but vocals are still clear and guitars/other instruments sound nice.
Highs here are shocking, with the first model of the Hesh, highs were almost no existent, and the upper-mids were very shrill. On the 2.0's, they are crisp and clear. I can not express how shocked I was when I tested Propane Nightmares ~ Pendulum. Great performance here.
Soundstage is about average for a pair of closed cans, maybe slightly larger. Seperation is decent at best. As for detail, I can only describe them as slow, and dark. All in all the headphone itself is pleasant to listen to.
Comfort is just OK, the cups are barely fit over the ears, may cause discomfort for users with earrings or glasses.
Overall these headphones are definitely worth the 60~ dollar price tag, as they blow away the XB500's that I owned in the past. Bassheads will enjoy this headphone. I highly suggest it to anyone looking for bass, with a nice SS.
