Purpose & Audience

The Boxwave C36 is a Bluetooth 5.3 audio adapter that adds wireless streaming to any wired stereo system. It is built for listeners who want to play music from a phone or tablet through existing speakers without running new cables.

Connections & Flexibility

The adapter accepts power over USB-C and offers RCA, 3.5 mm and optical outputs so it fits most home, car or legacy AV inputs. A USB port also plays files directly from a flash drive, removing the need for a separate source device during casual listening.

Sustained Streaming Behaviour

Bluetooth 5.3 keeps the link stable up to 33 feet with low latency and high-definition codec support for consistent quality. The receiver-only design means it cannot send audio to headphones or act as a transmitter for other gear.
