Stereo bluetooth doesn't work natively with a lot of devices in some cases you may have to do some research into how to make it function properly. For example, many Pocket PC's need a special A2DP cab file to make this work... I did.Some people have cited a "hiss"... This is a common issue on ALL audio devices... if the volume is too high. The solution is the same on all such devices. Turn the volume down. To get rid of the hiss, I turned the volume down on the head set by one or two notches and then upped the volume by the same amount on my PPC. Hiss was there after gone.As to it being awkward, it takes some getting used to that's for sure. I wear glasses so it's even harder with the limited real estate on my ears. But if you're willing to play with it for awhile until you get it right it's fine. As to it being bulky, only if you try and put it in your pocket. Put around your neck... it's fairly snug and comfortable.Summary:Great if you can deal with the following:1. Potentially technical set up on some devices.2. Unusual form factor takes some time to figure out.3. When you want to carry it but not use it, put it around your neck.Do the above and it's a great device.
