Bluetooth Built-in Microphone Bluetooth Receiver AUX

The Bluetooth Built-in Microphone Receiver from Gridlock turns a wired AUX stereo into a wireless one. Plug its 3.5mm jack into the AUX input on your car stereo, home amp, or powered speakers, connect the USB cable to a 5V power source, and pair your phone over Bluetooth 5.0. Music plays through your existing speakers, with no app or driver to install.

The built-in microphone is what sets it apart from a plain audio dongle. It lets you take hands-free calls and run voice navigation through the car speakers without touching your phone. Bluetooth 5.0 keeps the connection steady within a stated range of about 10 meters.

A few things to know before you buy. This is a receiver only, so your stereo needs a working 3.5mm AUX input for it to do anything, and it runs on USB power rather than a battery, so keep a USB port or adapter free. It comes in black and ships with the adapter and a manual.
