Pros: Pretty much everything, great sound quality
Cons: Cups are a bit flimsy and the headband never feels very secure
I needed something with decent isolation, and with decent comfort as I was forgoing my comfy DT990Pros which were open back.

Used with a Fiio E7 primarily
These were thankfully easy to drive, used them with my HTC One a lot. They are quite comfortable for extended hours of use but like any closeback, they leave my ears super sweaty.
I still have some reservations between purchasing this or the Ultrasone 900 but this is a great easily drivable, comfortable and a headphone with the sound signature I wanted.
But holy crap, these look great, like in real life they look amazing. Look better than most any headphone I've seen (I've only seen Beyerdynamic, Sennheiser, Shure, Hifiman and listened to in real life).
They are quite light due to the headband, easy to lug across campus. All in all I'd say 9/10, definitely would buy again.
