Bluetooth 5.0 Audio Adapter

This small dongle adds Bluetooth 5.0 reception to any device with a 3.5 mm auxiliary input and a USB power source. It streams audio from phones, tablets or computers to car stereos, amplifiers or powered speakers. The adapter draws power from any standard USB port, including power banks or vehicle sockets.

Suits cars and speakers without built-in Bluetooth

Buyers who want to modernise a hard-wired audio system will find this a simple plug-and-play solution. It is not intended for transmitting audio from non-Bluetooth sources to headphones, nor for users who require aptX or LDAC codec support. The 10 metre range also limits use to a single room or vehicle cabin.

Bluetooth 5.0 with A2DP and AVRCP

The adapter uses Bluetooth 5.0 and supports the A2DP, AVRCP, AVDTP, HFP and HSP profiles for stereo streaming and basic call control. This profile set determines whether your source device can send music and handle playback commands correctly.

Questions about this item

Does the JacobsParts BTR-A include a 3.5 mm audio cable or must I supply my own?

The adapter has a built-in 3.5 mm AUX output jack; no separate audio cable is included, so you provide the cable that plugs into your car stereo, amplifier or speaker.

Which Bluetooth version does the BTR-A use and why choose it over an older dongle?

It uses Bluetooth 5.0, giving a more stable connection and lower latency than earlier versions while supporting the same A2DP, AVRCP, AVDTP, HFP and HSP profiles.

What does the 10 m Bluetooth distance mean when the adapter is plugged into a car USB port?

The 10 m figure is the open-air range; inside a vehicle you can expect reliable playback from the driver’s seat and rear seats without drop-outs.
