  • The TX/RX switch allows you to select from Transmit/TX mode (for sending audio from a wired jack to your headphones) to Receive/RX mode (for sending music or directions wirelessly from your iPhone to a car’s AUX IN or to the AUX IN of a non-Bluetooth speaker).

  • Tx is transmit such as to Bluetooth speakers from a audio device. Rx is receive from a device (audio player of any sort) to Bluetooth headphones except AirPods. AirPods do not control volume and this is a known issue.
