Setup and compatibility tips

The B03S supports both optical and analog connections, so you can link it to most TVs and stereo systems. For TV optical output, set the audio format to PCM and output via Optical/Digital for normal use. When connecting to a sound system, you can choose RCA or 3.5mm depending on the inputs available.

Note that actual range depends on environmental factors like walls and interference from routers or other wireless devices. The B03S is designed to maximize compatibility and sound quality, offering a space-saving path to a modern, wireless-enabled listening experience without promising outcomes for every setup.
