As with most Bluetooth headphones, the idea behind the Reference Series 610 is to give you the ability to pump music into your ears up to 30 feet away from your iPod?s headphone port, without requiring you to run a wire between the headphones and the iPod. White and black versions are available, each with a small matching iPod transceiver dongle, which draws power from the iPod?s battery rather than requiring its own. You needn?t?
