Excerpt: After sampling most of the high end headphones at the chain tech shops, and then extensive research online, we chose to order these without having heard them. After receiving them, their sound quality is truly high end, and the construction features of this model are a match to the sound quality.
Summary: Tough in build quality, clear high bass, perfect mid-high, detailed sound. (but more bass). You will definalty lost in music. I used while cycling with Sony Xperia Z, best & comfortable noise insulating, no traffic noise, same feeling like listening music at home.
Summary: I ordered these expecting excellence seeing as all the headphones I have ordered from sennheiser have been, they arrived quickly and very well packaged (if a bit over packaged). In the box were all that was stated to be there by sennheiser and the box and headphones were well presented as usual.
Summary: Just bought a pair today, totally blown away !! Detail and bass extension are incredible, but not in an uncontrolled and messy way, would consider these an excellent set of studio reference headphones and to be honest are just great to listen to.
Summary: First of all, these will be compared to a pair of headphones that I already own and love - Custom One Pros. If you want a short review: Bassy (not boomy), great vocals and awesome highs, without them being tedious. A long review: BASS Jesus. I thought my COP were bassy.
