Wireless audio adapter for wired systems

This compact adapter adds Bluetooth connectivity to any device with a 3.5 mm auxiliary input. It receives wireless audio from a phone or tablet and plays it through a car stereo, amplifier, or powered speakers. A built-in microphone enables hands-free calls when paired with a smartphone. The internal battery recharges via the supplied Micro-USB cable.

For adding wireless streaming to an AUX input

Ideal for drivers who want to stream music through an older car stereo or for home listeners connecting a phone to a wired amplifier. It supports a single paired device at a time, so households needing simultaneous multi-user connections should consider a different solution. The adapter does not transmit audio from a wired source to Bluetooth headphones.

Bluetooth v3.0+EDR with A2DP

The adapter uses Bluetooth v3.0+EDR and the A2DP profile for stereo audio streaming. It operates within a 10 m range and pairs with a 0000 passkey when required. Power comes from the built-in battery charged over Micro-USB, and the 3.5 mm jack provides the only audio output.

Questions about this item

Does the adapter need any port besides the 3.5 mm jack on my speaker or car stereo?

It draws power through the Micro-USB port, so a USB charger or powered USB port is required alongside the 3.5 mm AUX input.

Will a phone running a newer Bluetooth stack still connect to the V3.0+EDR receiver?

Yes, the adapter uses the A2DP profile which remains supported by current phones, so pairing and audio streaming work normally.

How can I confirm the receiver has paired correctly after I hold the button for five seconds?

The LED under the button will flash blue slowly once pairing succeeds; a steady or alternating red-blue flash means it is still in pairing mode.
