2-in-1 Bluetooth 5.4 audio adapter

This compact adapter operates as both a transmitter and a receiver over Bluetooth 5.4. In TX mode it adds wireless audio to non-Bluetooth sources such as airplane seats, TVs or MP3 players. In RX mode it streams audio from a phone or tablet to wired speakers, car stereos or headphones via a 3.5 mm jack. The dual-link function lets two pairs of Bluetooth headphones listen simultaneously.

Stable connection and long battery runtime

Bluetooth 5.4 delivers a reliable link with low latency during extended listening sessions. The internal battery runs for up to 25 hours in transmitter mode and 23 hours in receiver mode, supporting long flights or road trips without recharging. A built-in high-sensitivity microphone enables hands-free calls while in TX mode. The LED display shows the active mode, connection status and remaining charge for quick troubleshooting.

Check your source and output connections

Verify that the device you want to connect has a 3.5 mm auxiliary or RCA output for transmitter use, or a 3.5 mm input for receiver use. The adapter charges via the included USB Type-C cable, so a USB power source is required for recharging. It is designed for stereo audio only and does not support multi-channel surround formats.

Questions about this item

Does the adapter get warm or drain quickly when used all day?

Battery lasts up to 25 hours in transmitter mode and 23 hours in receiver mode, so a full day of use is covered on one charge.

What cables or ports must I already have to connect this to my TV or stereo?

A 3.5 mm AUX or RCA port on the source device and the included 3.5 mm cable are all that is required.

Will my older Bluetooth 5.0 headphones pair reliably with this Bluetooth 5.4 adapter?

Yes, Bluetooth 5.4 is backward compatible with Bluetooth 5.0 devices, so existing headphones will connect without issues.
