I think you need to look for the feature known as "multipoint". This allows the headphones to pair and be actively connected to two devices at the same time - your N800/mp3 player and your phone. These are a bit more expensive than the normal Bluetooth stereo headphones, which can only connect with one device at a time. Simon
