US Patent 11032766 Wire-free bluetooth communication system with fast pairing

A power saving wire-free earpiece has a Bluetooth transceiver and a Bluetooth Low Energy (BLE) transceiver. A stream of audio from a remote source is separated into a local audio stream and a stream sent to the BLE transceiver for a remote earpiece. The earpiece is operative in a first and second mode, the first mode enabling the BT transceiver and BLE transceiver, the second mode enabling only the BLE transceiver for receiving remote streams of data. The first and second mode alternate so that the local and remote earpiece have substantially uniform current requirements.
