I got a pair of Plantronics bluetooth headphones. Work great with my iPhone. Sounds terrible with my Mac, cuts out, sounds choppy, sounds mono to me. A co-worker tells me he has the same problem.

BTW, I'm on Leopard, patched up.

So question is: What is the deal? Is it fixable?

What is the model? Does it support A2DP? What software are you testing with? Do you have friends that have Macs you can duplicate this on? –  Michael Glenn Jul 24 '09 at 16:51

Make sure that when you pair the headset you select "use as wireless headphones" (or similar) instead of "use as headset". The headset profile was designed for phone calls, and you should only use it if you're pairing a headset that does not support A2DP.

Your Plantronics headset probably supports both (if it has a microphone) because some devices switch between the two profiles for music-listening and call-taking.

Try the method explained in this post. It tweaks the bitpool setting which makes all the difference in the world.

Followed these instructions and got noticeably better sound quality. Thanks! –  Hassan Nov 9 '11 at 13:29

Ok You are on Leopard which supports A2DP, as opposed to non-stereo on Tiger so that should not be the problem.

Some headphones have a headset mode and get connected in that mode incorrectly and sound awful, so you should endure that your headphones are not being connected in headset mode.

You should also try your headphones with another computer to ensure that you bluetooth adapter is not faulty.

The headphones work fine with the iPhone, and most Macs have built-in Bluetooth, so testing with another system shouldn't be a problem. –  Andrew Scagnelli Jul 29 '09 at 17:31

I have a Motorola A2DP headset and on occasion with it pairs in headset mode with my MacBookPro it's very staticy and the sound is sub-par. Usually, by disabling bluetooth and then turning it back on and resyncing everything it works fine again.

It's pretty rare that it ends up with bad sound, but I get the feeling that Apple has pretty crappy bluetooth drivers.
