Abstract: A multiple audio gateway Bluetooth earphone, comprising an audio signal input module, an audio signal output module, a Bluetooth module, a key-in module; and a power supply. When the Bluetooth earphone is communicating via Bluetooth wireless connection with one of the audio gateways, another audio gateway may, via the existing or a newly established wireless connection, prompt another incoming call, and through the switching function built in the Bluetooth module, the earphone can detect the calling signals, and then trigger a signal to alert the user. The user may then choose to answer or ignore it, with the on-going call being hung up or put in waiting, or to invite the new caller to join as a multi-party phone conference.
