Summary: I got them today but I was able to give them a 4 hour listening sesh immediately. I A, B, C, veiwed them againstthe Shure srh440, Pioneer HDJ1500 and Apex HP96. The first thing I noticed was the lightweight but nice grip similar to the SRH440 in feel but not as tight as the Pio`s.
Pros: Comfortable, Light, Good Isolation, Traveler sturdy, Excellent Sound
Cons: Clearly designed in the 70`s (not that bad actually)
Summary: From the various headphones I have owned my favorite till now has been MDR-V6. I have the HD-25-1 II as well and from the perspective of sound they are very good but I am not a fan of on ear headphone.
Cons: Not really portable(but I don't care), ear pads
