    Ok I got a new macbook pro from colorwarepc, and a brand new pair of koss cobalt bluetooth headphones.

    So I have my little bluetooth arsenal: my mightymouse, my nokia 8801, and my coblat headphones. Until I got my headphones, I have been using my wireless mouse and transferring files to and from my phone simultaneously with no problems. Now, when I pair my headphones with my macbook, things start to degrade. My transfer rates on my phone drop dramatically, and my mightymouse becomes sluggish. The audio quality coming out of the headphones is pretty bad as well. I thought to my self, ok the headphones suck, send them back. But just to test this a little more, I used the USB->Bluetooth adapter Koss included with the cobalt. When pairing the headphones with the usb adapter, i get crystal clear quality and my mouse sensitivity and mobile phone transfer rates dont wane.

    So my question for you all is, could this be a bluetooth problem with my macbook? I would take my machine to a mac store but there are none near me :(

    Have any of you paired more than 2 devices, one streaming audio, all using the macbooks internal bluetooth radio with any success?

    Well you do have to remember that like any other radio signal, you have to take bandwidth into consideration. Bluetooth is a very demanding feature because it both requires power in all of processes such as sending/receiving data and also looking for other devices.

    Not all bluetooth radio signals are the same, especially in the MacBook Pro. The MacBook Pro has a soldered in chip that sends radio signals and probably doesn't have a full blown antenna, as to where a USB dongle device has better range because of the built-in antennas it has, and that signal strength has a good correlation with how much data can be transferred.

    I can understand a couple of devices, but you have some pretty demanding devices that need constant data transfers such as your BTMM and especially your headphones.
