Wireless Audio Adapter

The Auto Ventshade AUB09B27J11J is a compact Bluetooth 5.4 adapter that adds wireless streaming to any device with a 3.5 mm auxiliary input. It operates as both a transmitter and a receiver, letting you send audio from a TV or PC to wireless headphones or stream music from a phone to a wired car stereo or speaker system.

Drivers and Home Listeners

This suits drivers who want hands-free calls and wireless music in an older vehicle without replacing the factory head unit. It also fits home users who wish to connect Bluetooth headphones to a television or revive a legacy amplifier. Buyers needing a built-in display, multi-device pairing or aptX codec support should consider other options.

Bluetooth 5.4 Connectivity

The adapter uses Bluetooth 5.4 for a stable link up to 33 feet with low latency and noise cancellation. A single charge powers extended playback sessions and the unit automatically reconnects to the last paired device when switched on.

Questions about this item

What audio source does the 3.5 mm AUX input on this adapter connect to?

The 3.5 mm AUX input connects to non-Bluetooth sources such as a TV, MP3 player, CD player or PC so the adapter can transmit their audio wirelessly.

Will the adapter pair automatically with my phone the next time I start the car?

Yes, when the ON/OFF switch is turned on the adapter enters pairing mode and automatically reconnects to the last paired phone.

How can I confirm the adapter is transmitting audio correctly after setup?

Audio plays through the paired Bluetooth headphones or speaker, and the built-in microphone lets you answer calls with the power button.
