I made a mistake and only bought the Plantronics Voyage Legend Bluetooth headset. This worked great as a headset for my iPhone. But I didn't have the option (or at least couldn't think of it) to pair with my Macbook Pro either. I realized too late that I should have bought the Plantronics Voyage Legend UC in the first place. UC means that the kit includes a USB adapter for connection to a computer. Luckily I found that this USB adapter is available separately from Plantronics. I plugged it into one of the USB ports on the back of the Thunderbolt display. The headset is easy to pair. Now it can be connected to my iPhone and my computer as a headset at the same time.
