The Asus USB-BT21 is a USB accessory that adds Bluetooth connectivity to a Mac or PC. The USB-BT21 supports Bluetooth v2.0+EDR, while the latest model, the USB-BT211, upgrades to v2.1, which simplifies device pairing, among other minor differences. Both versions support data transfer rates up to 3 Mbps, more than enough for the transmission of stereo audio to Bluetooth headphones. The USB-BT21 is extremely compact and available in five colors.
