These headphones are great in every aspect except for comfort. They're the behind-the-head style that's oh-so-popular these days, but the fit is far worse than the comfortable (but breakage-prone) Logitech Wireless Headphones for iPod that I had before. These pair easily with my bluetooth-enabled Thinkpad, which is nice, and also with my phone (at the same time) so I can take calls and it will switch from the music, then switch back when my call is over. The built-in mic works surprisingly well, for a really hassle-free bluetooth experience.Now for the bad: I feel like these headphones were designed for kids. They're so small (I was really shocked when I opened the packaging at how small they are) that they pinch my ears hard. The headband just simply isn't big enough for a normal-sized head. Another minor thing is that they have a mind of their own when you put them down. If you sit them down with the earpieces facing up (which you invariably will when you have to take your hourly break from the pain they cause), they "walk" themselves off of the desk if you put them down the wrong way.
