PDAs, Cellphones, Wireless The Bluetooth headset has gone from nifty novelty to ubiquitous accessory. They've become better and better with each generation, so now that they've matured, just how good are they? And what use are they for something other than making you look like you're talking to yourself?

A2DP

The quality of the audio is only going to be good as the quality of the codec implementation in the headset. Because of the way A2DP works, the headset is effectively the real "media player". Also, if the headset doesn't support the encoding of the files you're playing or your player isn't written to support A2DP directly, the audio has be decompressed, re-encoded into something that is supported, and the decompressed again. How's that for brain damage?

The only way this would make sense to me is if it were streaming raw PCM, but bluetooth doesn't have the bandwidth for that. The way it is now, not only does the headset have to have logic to support the bt protocol stack, but it has to implement a bunch of audio codecs. So they're not really just headphones but a portal media player that sits on your head and uses your iPOD --or whatever-- for storage.
