These headphones are probably my favorite. I love the design; the ergonomics fit so well. The large cups make it impossible to feel uncomfortable with. The open back makes the mids and high sound much more fuller and dynamic. These compared to the K701 has a bit more bass, so they feel more up to date to popular styles of music (Im talking about EDM and hip-hop stuff.) Great cans!
Has a really flat and natural Freq response and are really comfortable. The headband gets worn out pretty quick, leading to them falling off your head easily.
