I bought these to replace my Sennheiser HD25-I as they were quite uncomfortable to use for extended periods of time.
 
Whilst these are incredibly comfortable, the sound isn't something I'm used to. The highs are quite tinny no matter the genre. They need some wearing in, I suppose, but for $169, they're a great headphone.
 
The main reason I love them is because of their cables. They're thoughtfully designed and allows me to use it on my phone without having to remove the case.
