Anyone use these? In particular, the Logitech model. How are they? Are you able to use these with a powerbook as well?

I have the same question

I would think that if the Powerbook in question had Bluetooth, it should be able to bind with the headphones and they should work just fine. I have used a couple of different Bluetooth devices with my Power Mac, which I purchased with Bluetooth built in. One of the devices was a Motorola Bluetooth ear piece that I use with my cell phone. I am able to use it for things like Skype, etc.

The only gripe that's stopped me looking into BT headphones is the fact that you can't get a high enough data-rate over BT to reproduce high-fidelity sound. It's fine for things like hands-free mobile sets because the quality of the audio is so low anyway. But if you're listening to CDs on BT headphones, I imagine the degredation in quality would be quite apparent.

Hmmm...uncompressed CD audio files use 10MB per minute (10584000 to be exact). Divide that by 60 seconds, and you have a data rate of 176,400 bytes per second. That's well beyond the actual BT data rate of about 730,000 bits/sec. I wonder what they do to get the rate down for headphones? And I wonder if any of the headphones support BT 2.0 data rates?

I should have added that what I posted was based on what I had read elsewhere on the forum .... I haven't *actually* tried it for real ...

I think Bluetooth headphones use some type of lossy compression. BT 2.0 headphones, if/when they become available, should be able to transmit uncompressed CD quality PCM.

I didn't realize they didn't use 2.0

There is another issue here, which is that there are many flavors of bluetooth. Not all devices support stereo over bluetooth as it's a relatively new addition to the Bluetooth scene. This is why a lot of stereo bluetooth headphones come with their own usb adaptor that hopefully will support stereo.
