ZIOCOM BT4853C Bluetooth 5.0 adapter

The ZIOCOM BT4853C is a 2-in-1 wireless audio adapter that operates as both a Bluetooth transmitter and receiver. It connects non-Bluetooth TVs, PCs or stereos to wireless headphones or speakers using a simple mode switch. The device supports Bluetooth 5.0 for a stable connection and includes optical, 3.5mm and RCA interfaces for broad compatibility. It is suited for users wanting private TV listening or wireless music streaming on existing wired systems.

450mAh battery with 20h runtime

A built-in 450mAh battery provides up to 20 hours of continuous wireless operation before recharging is required. The unit powers via a 5 volt DC supply, allowing use while charging for longer sessions. In transmitter mode it streams audio to two paired headphones simultaneously, while receiver mode accepts connections from two source devices. Battery life will vary with volume level and codec negotiation.

Compact build with optical and analogue inputs

The black adapter features a physical TX/RX toggle switch for instant mode changes without menus. Optical, 3.5mm auxiliary and RCA cables are supported, covering most legacy and modern audio ports. Dual-link capability lets two listeners share TV audio or two phones queue music on a stereo. The design omits a remote control, so all pairing and mode selection is handled on the device itself.

How can I confirm the BT4853C is paired and streaming correctly after I switch it to TX mode?

The LED indicator shows pairing status; once connected, audio plays through both paired headphones simultaneously with no noticeable delay.

Does the BT4853C come with an optical cable and RCA leads, or must I buy them separately?
