What this adapter does and who it suits

The SMA Bluetooth 5.3 transmitter-receiver adds wireless audio to devices with a 3.5 mm jack. It switches between TX mode for sending audio from a TV or stereo to headphones and RX mode for streaming music to a wired speaker or car system. Travellers can use the included airplane adapter for in-flight entertainment.

Practical limits of the Bluetooth 5.3 link

Stable transmission is specified within 10 metres. Latency depends on the receiving device codec; aptX Low Latency is required for the lowest delay, otherwise expect 70-200 ms with SBC or standard aptX. Battery life reaches 16 hours in TX mode and 13 hours in RX mode.

What to check before ordering

Your headphones or speakers must support aptX Low Latency if minimal delay is important for video. Professional instruments such as guitars or pianos are not recommended for this adapter. Verify the source device has a 3.5 mm output and that no other Bluetooth device is already paired and blocking the connection.
