just got this in today...
Plantronics Voyager 855
It works as a regular bluetooth headset and a A2DP with/without the attachable stereo earpiece.
This is my first A2DP mobile experience.
Works real well with the Touch. You can switch tracks, control the volume, pause/play all on the headset (with WMP or AM only, TCPMP and other audio programs don't let you controll the play thru the headset.)
The call quality of this headset is decent.. not as good as my Jabra jx10. The headset comes with ear gells that are made for sound isolation. You can make calls as a stand alone headset or with the stereo attachment... I prefer the stand alone. The stereo calling sounds too trippy for me. It also has a slide boom to answer calls. You can answer calls without sliding the boom.
The music quality is very good... better then regular headphones on my ipod it seems. The bass response is very impressive from me. And this is coming from a freelance audio engineer.
The only real complaint I have is the fitting. The headset has this part that sticks, litterally, in your ear and kinda leaves the headset hanging off.... so it sticks out and not up against your cheek. It leaves you with that "loose" feeling like its going to fall off if you move your head around. Even though I shaked and moved my head around to see if it would, the feeling is still annoying. The ear hooks really don't help for me... Simply the headset is staying in just from the part thats going in your ear.
But all and all, its a pretty damn good headset... especially for A2DP.
Based on my mood, I'll be switching between this and my jx10
