The hardest part, for me, was getting the audio transmitter. That’s where avrcp (AV remote control) bit me, because i didn’t know it was a separate profile from a2dp (stereo bluetooth) and then in addition, you’ve got class 1 and class 2 bluetooth devices. class 2 are the “default”, but the range is fairly short and microwave ovens disturb it at work

i switched to a class 1 device, and now i can go upstairs and still have music. Then on top of class 1 and avrcp, you also have to know what media players it supports for the avrcp

(the bluetooth stack, rather; not specifically the transmitter) but the transmitter i got used the toshiba bluetooth stack, which has avrcp but only for a handful of players (not itunes) so if one were to buy a bluetooth audio transmitter, i would say: a2dp, avrcp, class 1, and comes with the bluesoleil bluetooth stack…for windows. i just realized macs probably have builtin a2dp/avrcp and would certainly be compat with itunes.

the specific headset i have is the Sony DR-BT22 and i don’t have any major complaints. music sounds good, it’s reasonably comfortable, and it’s got good battery life. It does have a flimsy feel to it because it’s foldable, but it doesn’t bother me.

the transmitter i have (for the pc) is a Zoom class 2 bluetooth 2. it works as advertised, but i don’t necessary recommend it. it came w/ the toshiba bluetooth stack, which doesn’t work with itunes. so i like the stats of the zoom, but i’d recommend a transmitter that comes w/ the blue soleil stack instead (since it works with itunes).
