but, apparently you were using the wrong terms to find what you wanted.
Take a look here:
Kinda expensive, but that's relative, but they do have a good writeup and will work with your Mac.
The search term I used was Bluetooth Headphones. Brought up a bunch of them.
I have a Late 2008, White 13" 2.1 GHz Intel Core 2 Duo with 4 GB 667 MHz DDR2 SDRAM,
Bus Speed: 800 MHz Boot ROM Version: MB41.00C1.B00 SMC Version (system): 1.31f0

Apple Bluetooth Software Version: 2.2.4f3
I would LOVE to pair a decent Bluetooth headset to the laptop for DVDs, iTunes while I surf/Facebook/etc. However, whenever I look on the Apple or CNET websites for Bluetooth headsets, all I can find are headsets for iPhones, MP3 players, etc, but none that indicate use with a MacBook or a laptop. Can someone tell me if I can get a Bluetooth set for this purpose and what modifications or upgrades, if necessary, are needed? More tech data related to my system are shown below in case it helps answer questions I'm not smart enough to ask.
