Wow thank you very very much! I arrived here after returning a bluetooth logitech wireless speaker I bought to stream music from my iMac to my HiFi gear. It didn’t sound perfect with the mac but it sounded perfect with the iPhone. So I searched the web and I saw this thread. I bought another logitech unit after set bluetooth value to 50 via: defaults write com.apple.BluetoothAudioAgent Apple\ Bitpool\ Min\ \(editable\) 50 and it works very well. The sound is fantastic, as with the iPhone, and it’s great to have access to 30.000 songs far from the computer. Mine is now 12 meters away from reciever and I have no drops in the signal. Thank You! A real alternative to airport express to me.

I just wanted to chime in with a Thank you for everyone that posted. I went with Martin and Eldroid’s suggestion of editing the PList for the Bluetooth Audio Agent. Worked like a charm.

I tried using a Jawbone Jambox on my Macbook Pro, and it sounded like I was playing an AM radio. I tried it on my iphone and it was fine. I thought I was having a failure in my bluetooth chip, but it turns out the chip was just set too low. Bad Apple I tried it at 50, and it works great.

I’d advise using an Editor like Martin suggests rather than the command line. I tried it with the command line and it stopped working altogether. After opening with the plist editor i noticed that the value was set as being a String rather than an Integer. After i changed that, it worked fine again. Also, the best way to start it working is to open bluetooth control panel, click MW600 in the list, and then use the little gear icon to choose “Use as Audio Device (Stereo)”. Other methods of turning it on are less reliable in my experience.

Those of you getting syntax errors, note that you can’t just copy/paste the text from the article. The quotation marks have been replaced with “smart” quotes, which the terminal doesn’t know how to translate into regular quotes. copy/paste what’s in there, then manually delete the quotes and re-type them.

Set it to 44. Works like a charme w/ the Nokia BH-905. Thanks for this tutorial!

I found after some fiddling that 44 gave me the best sound on Philips SHB9000 headphones

try this from a terminal

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 44

Thank you so much, I have a pair of Sennheiser MM450 and I was looking for a bluetooth quality improvement on my MacBook Pro since months!

P.S.: I used the code posted by Kirpi 'cause the one in the guide returned a bash error.
