Golvery J207 Bluetooth 5.4 Receiver with Mic & Volume Control

Bluetooth 5.4 Audio Adapter for Older Systems

The Golvery J207 adds wireless streaming to any speaker, car stereo or wired headphones that have a 3.5 mm auxiliary input. It pairs with smartphones, tablets or laptops and is powered by an internal 240 mAh battery that charges via USB-C. The unit measures 1.7018 cm by 9.4996 cm by 11.5062 cm and weighs 15.4 grams. It is not a transmitter and cannot send audio from a TV or PC to Bluetooth headphones.

Fits Between Source and Wired Playback

A 3.5 mm cable is included to link the receiver’s output to the auxiliary port of the target system, so no special wiring or dashboard work is required. Bluetooth 5.4 handles the wireless link up to 33 ft and supports dual-link pairing, letting two devices stay connected at once. The built-in microphone enables hands-free calls with one-button answer, redial, hang-up and reject. Power comes from the rechargeable cell, freeing the installation from a permanent 12 V feed.

Runs 20 Hours While Charging

The battery delivers about 20 hours of continuous playback after a two-hour charge and the receiver stays active during charging so the stream never interrupts. Bluetooth 5.4 and the upgraded chipset keep the connection stable through the full session, and the device automatically reconnects to the last paired sources when switched on. This makes it suited to all-day use in a vehicle or at a desk without a wired power supply.
