Summary: I just can't imagine why the mic boom is this short. My head is by no means large. I would say I have very nearly the perfectly average sized head for hats, etc. I have had jobs aplenty where I had a mic boom that worked perfectly fine. It is a real blight on a product that would otherwise have gotten a 4 or 5 from me.
Pros: Wonderful sound. Comfy. Does not make my ears hurt even with long wear.
Cons: The mic boom is worthless. It is simply not long enough to get the mic to the proper position in front of my mouth. If I take the left earphone off of my ear, I can get the mic positioned and it works fine.
Summary: I got these headphones in November 2012 and come July 2013 they are broke. No sound or mic input, these have been looked after carefully. Over time they became temperamental, deciding when and if they were going to work. I have bought Sennheiser headphones over the years and been happy until this set. WOULD NOT RECOMMEND to anyone interested in headset that is needed to last over a year.
Summary: Well, for starters, right after un-boxing I noticed how cheap it looks and feels, and then we get to the actual testing. The sound quality itself is not awful, but leaves much to be desired. You can not wear these headphones for more than an hour without your ear starting to hurt, and my pair fell apart after three weeks of use.
