Ruth's sister V5.0 Bluetooth 5.0 3.5 mm audio adapter

Bluetooth 5.0 receiver with 3.5 mm output

This Bluetooth 5.0 receiver adds wireless audio to any device with a 3.5 mm auxiliary input. It uses a BT300 chip and a V5.0 decoding chip to deliver HiFi sound quality with a signal-to-noise ratio above 110 dB. The frequency response spans 10 Hz to 20 kHz and impedance is rated at 75 ohms. A2DP and AVRCP protocols handle stereo streaming and basic remote control.

Users wanting wireless audio for wired speakers

The adapter suits anyone who wants to stream music from a smartphone or tablet to a home stereo, car stereo or wired headphones without replacing existing equipment. It pairs once and reconnects automatically on power-up. Buyers who need aptX or LDAC codec support should look elsewhere, as the specification lists only standard A2DP. Users requiring a built-in microphone for calls or a battery for portable use will also need a different device.

3.5 mm auxiliary interface

The sole physical connection is a 3.5 mm AV audio output jack, so the receiving device must provide that exact input. No USB, optical or RCA connections are present. The unit measures 11 cm by 7 cm by 3 cm and is built from ABS and metal. Multifunction buttons control volume and pairing through long and short presses. Power is supplied externally via the connected audio equipment.
