Be cautious regarding these headphones. I bought these as part of a Groupon deal they had going on, and they were more or less defective right out of the box. I had horrendous feedback on the right ear cup if the external ANC mic was slightly covered at all. It could be reproduced at any point in time. Plus, there was a slight ring in that same side.

A friend just got his in a few days after mine, and did not have any problems. Clearly their quality control is suspect and I would not be surprised if it is non-existent. Plus, when you switch the ANC on, the volume gets amplified 2x easily, so the batteries are likely going to die sooner as well.

The ear cups are a bit small. They can't be folded to a compact size to begin with, so why they wouldn't make the ear cups slightly larger is beyond me. You sort of have to fit your ear into them at an angle and then they'll fit over just fine.

I contacted customer service right after I got them, and still haven't even gotten a RMA number 5 days after getting a request to give them product ID/SN information.

Buy some ATH-M50 on amazon when they drop to $115.
