Bluetooth 5.3 AUX Adapter for Car & Home

The TISONNY J39 is a compact Bluetooth 5.3 receiver that adds wireless audio to any device with a 3.5 mm AUX input. It streams music from a phone, tablet or laptop and supports hands-free calling through a built-in microphone. The silver unit measures 2.2 by 1.3 by .24 inches and weighs 1.76 ounces.

Upgrade from Wired AUX or Older Bluetooth

This adapter replaces a physical AUX cable or an earlier Bluetooth dongle that drops connections or lacks a display. The jump is worth it when you want stable Bluetooth 5.3 streaming, a visible LED status screen and a multifunction button for call control without touching your phone. It plugs directly into car stereos, home systems or wired headphones.

16-Hour Battery with Type-C Charging

A full charge delivers up to 16 hours of continuous playback or talk time, and the receiver operates while charging via the included Type-C cable. The 5-volt input keeps top-ups quick during long drives. Battery life will run out on multi-day trips without a power source, and the single 3.5 mm connection means only one wired output at a time.
