Summary: Build quality and looks: These cans look very stylish. I like the silver disk-like design on the top of the earcups, similar to xb90ex. These headphones are quite sturdy, I expect them to be durable.
Comfort: These are among the most comfortable headphones I ever worn.
Pros: powerful bass impact, dark sound, soundstage, good treble, comfort, price
Summary: Got these from my brother who bought Senn-Momentum and he no longer need his first portable headphone so decided to give it a shot.
Gear used: WA7 FireFlies with EH golden pins Tubes as for the DAC and AMP, iFi-iUSB power supply, PC with Winamp+, also M-Stage (opa627)
Comfort: 1/5, they might be on...
Pros: sound good with after EQing and long burn yet not for that price....
Cons: muffled sound without EQing, punchy bass that isn't tight , over priced.
