Dual-mode audio adapter

The 528 FACTORY KN319 adds Bluetooth 5.0 to devices that lack it. In transmitter mode it sends audio from a TV or stereo to wireless headphones. In receiver mode it brings phone or computer audio to wired speakers. A sliding switch selects the direction instantly.

For non-Bluetooth sources and legacy systems

It suits anyone who wants wireless listening from a TV, CD player or older amplifier without buying new hardware. It also suits users who want to stream music from a phone to a vintage hi-fi. Buyers needing aptX low-latency codecs, multi-point pairing or ranges beyond 10 metres should look elsewhere.

Bluetooth 5.0 with 3.5 mm and RCA connectivity

The adapter supports Bluetooth 5.0, A2DP and AVRCP in receiver mode. It ships with a 3.5 mm aux cable and a 3.5 mm to dual RCA cable for broad analogue compatibility. A 200 mAh battery gives up to 6 hours reception or 5 hours transmission per charge.
