Bluetooth 5.4 dual-mode adapter

The Ankilo CP342 is a 2-in-1 wireless audio adapter that switches between transmitter and receiver modes. It streams audio from a phone to wired speakers in RX mode, or sends TV and in-flight audio to Bluetooth headphones in TX mode. Dual Link lets two headphones connect at once for shared listening.

Check your device ports

Verify that your source or destination equipment has a 3.5 mm AUX jack, because the adapter connects only through that analogue port. The USB-C socket is used solely for charging the internal 300 mAh battery. No remote control is included, so mode changes are made on the unit itself.

Sustained-use battery performance

In continuous receiver operation the battery lasts up to 11.5 hours, while transmitter mode runs for up to 10 hours before recharge is needed. A full charge takes 1.5 hours via USB-C. The LED display shows real-time battery level and active mode so you can monitor remaining runtime during long sessions.

Questions about this item

Does the CP342 include a 3.5 mm cable or must one be purchased separately?

The adapter has a built-in retractable cable with a 3.5 mm plug, so no separate auxiliary cable is required.

Should I choose the RX or TX mode for watching TV with two Bluetooth headphones?

Use TX mode; it streams audio from the TV to two headphones simultaneously via Bluetooth 5.4 Dual Link.

Up to 10 hours of continuous transmission, and a full recharge takes 1.5 hours over USB-C.
