There are a lot of topics in the forum about people having trouble finding compatible headphones to work for music and "remote" control the phone playback.
the Bluetooth A2DP works perfectly fine in SGS for both Car Receivers and Stereo headset, and it switch transparently between music to phone calls and back without a glitch.
(i can't say the same for WM phones, another reason why i left WM platform, PalmOS was good, but is no longer produced)
There are lots of excellent Stereo BT headphones in the market now, both Studio like or simple 1 ear type, whatever ticks your fancy, the studio type offers the best audio quality even over BT.
yes it might consume more battery, but battery replacements are very inexpensive. (see accessories section)
I've not looked back to use a wired headphones since BT Stereo was invented, i used to have wired headphones for breakfast, it was a mass murder of headphones every time you get in the bus or subway, i've saved a lot of money since i moved to BT, so it's very surprising to still see people trying to work out the wiring problems with the headsets
I've been there before, every time i switched to a new phone, i needed to find another adapter to convert this to that, so that i can do something as simple as answer the phone on the headset, it was a major PITA.
so it'll be interesting to hear your side of the story to prefer wire over BT (other than "saving" battery and "better sound quality")
