Mac OS A2DP and FreePulse Logitech Headphones

Apple is slowly fixing the many issues with it’s A2DP driver. In 10.4 the driver would kernel panic as often as it would work. In 10.5 it’s functional but only with a special trick to get it to change the audio channel correctly. Simply turning on the headphones and clicking “Use Headphones” on the dialog rarely works.

The trick is to run through this sequence twice. Turn on the headphones by holding the button on the right ear. After you hear the ping Mac OS will prompt you to use the headphones. Choose the option to use the headphones and the bluetooth icon will switch to connected. Now turn on the headphones again and when you hear them ping the bluetooth icon should switch back to disconnected. Under the bluetooth menu choose “Use Headphones” under the FreePulse device. The icon will stay disconnected but when you play audio it will switch to connect and start functioning.

I couldn’t find a place on apple’s site to report the bug with repeatable test case. If any of you know how to report bugs in Mac OS please tell me and I’ll file it so hopefully this behavior is fixed in future releases.

    I have found the A2DP support in Leopard flaky as well. Aside from the initial connection issues you mention above, there are also issues with disconnecting. Sometimes iTunes just crashes. This is a good thing in an office environement however, since then at least you dont end up blasting the office when you go to the toilet with your headphones on, but forgetting that the toilet is too far away to keep the connection up.

    As a result I prefer using the bluetooth to 3,5mm dongle that came with my Plantronic Pulsar headsets.

    Speaking of which, I lost them this weekend :(
    Now I am pondering what to get as a replacement. I liked the Plantronics (aside from the obnoxious blue blinking, which is a trademark thing found on most BT devices unfortunately). The only thing I would love to have is BT 2.1 support. Even if my phone does not support it now, it supposedly draws less power once I do get a new phone sometime next year.
