A lot of info can be found on the BT8010 here and on Jabra. Here are some of my personal impressions I didn't find elsewhere:- Comfort: the flexible ear loop is the key for wearing the headset. Attaching the headset via the ear buds ONLY will cause you great pain. It took me some "flexing" until I got the right bend. The BT8010 is bigger than the average headset. Comfort is the BT8010 weakest point.- Sound quality: in my opinion, this is a headset+headphone, not a headphone+headset. I estimate the sound quality to be equivalent to a $15-$20 in-ear headphone. You should have no problem with volume.- Audio controls: when listening to music, you can only play/pause or skip. You cannot fast forward, go back, etc. Again, headset first, headphone second.- Bluetooth range: I'm no Bluetooth expert, but I think of Bluetooth signals as light that can go through stuff. But don't expect the signal to cross your entire body. Having line of sight is always better. Just like light, I think Bluetooth signals bounce off walls. I experienced indoor reception (no walls in between) to be better than outdoor reception. Bottom line, your range will depend on where your phone is: it can be anywhere from 3 to 30 feet.- Noise cancelling: the jury is still out. I think my Razor V3 does a much better job, but may not be a fair comparison. My wife definitely knows when I'm on the headset.- Display and controls: many headsets talk to you via flashing lights only. Not the BT8010. Having a display makes easier to manage the headset. After all, you are connecting to 2 devices, in music or phone mode. It is possible to tuck away your phone and do lots from just the headset. The BT800 features caller ID, a small phone book, voice dialing, and vibrate mode. The OLED display looks really good, I was impressed.- Look factor: honestly, in stereo mode, it will look like you are wearing 2 headsets. I personally avoid stereo mode in public. That said, I do use in stereo mode quite a bit. Phones calls are a lot better and listening to podcasts is great in the semi-privacy of my car.
