Terrible Bluetooth A2DP audio quality

Hey,

Bluetooth audio has always been a bit precarious with macs, I was having unbearable crackling with my Jaybird Freedom headset when paired with my macbook pro (though when paired to my iphone it was completely fine). The solution you posted just worked for me when I turned it up to about 45 (I've seeen a range anywhere between 40 and 58), so maybe fiddle around a bit with those numbers, remember to turn off and back on the bluetooth device for it to take effect (restarting my mac wasn't necessary). If that fails, I remember using terminal to create an A2DP connection before it was integrated into OSX (way back in either tiger or leopard). It vaguely resembled something like this:

It was so long ago I can't remember the exact specifics or which instructions I followed, but the terminal command in the instructions in the link above seem awfully familiar. I haven't tried those instructions in Lion (again, cuz the previous solution worked) but thought it might get you on the right track for an alternative. Best of luck.

I found 53 worked well (OSX 10.8 MacBook Air 2011) on my brand new Jaybird JF3 Freedoms:

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 53

Higher than that and it would not work at all. The original default, 2, was so awful as to be unusable.

Thanks for this - fixed the crackling/clipping on the JBL Jembes I stream to from my 2012 Air.

I had set mine to 50 but it didn't work. I've been testing just for a few minutes with 53 and it seems to be working. I'm running Mountain Lion on an Early 2011 MBP 15".

dont mean to bring up an old topic but i did what mmmax suggested seting the bitrate to 53. i have the same logitech adapter as the op and it sounds so much better now. thanks

Working great now after setting to 53 on my MBP running Lion. Headphones are Jaybird BlueBudsX. Thanks!

Excellent find! Thanks! I had completely given up on routing audio to my bluetooth headset, and then I found this! It actually sounds.... good!

Just found this. used 53 as a value for Bose Sound Link Mini and macmini pair. Dramatic improvement in sound quality and no cracking/popping. Appreciated

I Have some Creative T15 bluetooth speakers and when I connect these to my Mac (Yosemite 10.10.3 purchased in January this year) after a while I loose the sound effects on the Mac , but the normal sound,music/video playback is okay. When I connect the speakers via cable, I do not get this problem. When this happens, if I reboot the mac, the sound effects are okay. The problem does not happen with the internal speakers, I have contacted apple support via chat and there were no problems found. Is this something to do with A2DP?? Still getting used to using a Mac after over 20 years on windows!!
