I bought these headphones primarily for listening to music at work. I'm just now starting my second full day using these headphones and, except for some minor setup difficulty, they are working wonderfully.I've paired them with my Motorola Droid X and MacBook Pro (OS X 10.6.7). The pairing process was easy although not intuitive, reading the manual was a requirement. After pairing, I had to turn off Bluetooth on my phone in order to get the headphones connected to my Mac. It took me a little while to figure this out and I spent about 20 frustrating minutes fiddling with the Mac settings without success.I haven't made extensive use of the microphone, but attempting to use it to give voice commands to my phone was a complete failure. The quality of the mic didn't allow the phone to correctly interpret any of my commands, despite my attempts to speak loudly, slowly, and clearly.The rest of the functions work well with both my phone and laptop. The sound quality is reasonably good for wireless headphones. The volume is sufficient for the relatively quiet environments in which I've used them so far.The headphones are smaller and lighter than I had expected. I was afraid that they would press on my ears rather than fit over/around them. However, after wearing them all day yesterday, I found them to be quite comfortable. YMMV depending on the size and shape of your ears.The battery life so far is great. No problem using them all day on a single charge.
