I have owned a number of bluetooth headsets over the years and haven't been satisfied with any of them. The one which came closest was the BT800, Jabra's previous BT headset with a LCD screen on it. I really liked it, but had two issues with it. The first was that the loop which slipped over your ear was very flimsy and broke. Jabra sent me a replacement loop free in the mail, but it was annoying to deal with in the first place. The second issue was that within a few months of purchase the battery had degraded to less than a 1/3rd of original talk time. The battery is non user replaceable and Jabra's response was that it was time to buy a new one. At $250, I wasn't exactly happy with that response. In the past few years I have spent more money of BT headsets than I have on cell phones, and I have owned more phones than headsets (and I buy my phones direct, bot subsidized). I have no desire to own another headset unless the battery is user replaceable, preferably by a single AA.

I would love to see wireless headphone support on the N800, but have had such a consistently crappy experience with BT headphones/headsets that I am not willing to just throw more money down that hole.
