My wonderful, cheap, but technically crappy Samsung SBH600 headphones couldn't handle this. The follow settings worked there:

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Max (editable)" 64
defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 30
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool (editable)" 30
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool" 30
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Max" 32
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Min" 30
defaults write com.apple.BluetoothAudioAgent "Stream - Flush Ring on Packet Drop (editable)" 0
defaults write com.apple.BluetoothAudioAgent "Stream - Max Outstanding Packets (editable)" 30
defaults write com.apple.BluetoothAudioAgent "Stream Resume Delay" "0.75"

This made no difference for me. I have the latest MacBook Pro and an LG HBS730. The sound over bluetooth from my iPhone 4S is great, but from my MacBook Pro it is on par with a bad cell-phone connection (mono, wavering), and the above defaults writes seemed to not change it at all, even after rebooting everything.

You can try setting the codec to AAC lossless using the Bluetooth Explorer App on Mac. It's downloadable from Apple.com
