MD-HPBT01 Modal Bluetooth Headphone Multi Pairing ▮ Before you can connect the headphone to two devices, you must pair to each device individually. The device you are pairing must support one of the following Bluetooth profiles: • A2DP (Advanced Audio Distribution Profile)—Provides high quali ty A udio (stereo and mono) communication between the headphone and a phone’s or computer’s MP3 player. • AVRCP (Audio Video Remote Control Profile)– Lets a MP3 player control the headphone media playback buttons (such as play/pause or rewind/fast-forward). If you c onnect an MP3 player, the player must support AVRCP. See the documentation that came wi th the MP3 player to determine if the player s upports AVRCP. Windows M edia Player supports AVRCP. • HSP (Heads et Profile)—Provides two-way communication between the headphone and a Bluetooth phone. This profile is the most c ommonly used profile for Bluetooth phones. A paired phone must support HSP or HFP. See the documentation that came with the phone to determine if the phone supports HSP or HFP. • HFP (Hands-Free Profile)— Provides two-way communication between the headphone and a Bluetooth phone. If the phone does not use HSP, it uses th is profile. A paired phone must support HSP or HFP. See the documentation that came with the phone to determine if the phone supports HFP or HSP. ▮ A profile can only connect one device at a time. For example, you cannot use a phone’s MP3 player and a computer’s MP3 player at t he same time, because both players are connected through the A2DP profile. ▮ You c an connect a phone and a computer at the same time because the phone uses HSP or HFP and the computer uses A2DP. This lets you listen to music from the computer and answer phone c alls at the same time. Notes: In multi-pairing mode, some functi ons may be restricted depending on the host…
