Other devices — Jvc (Japan Victor Co.) Kenwood SP-WS10BT

The most interesting thing here is the wireless operation scheme. The JVC Kenwood SP-WS10BT speaker receives an audio signal from a small transmitter that is connected to the TV via an optical digital interface or via an analog 3.5mm jack. The transmitter plugs into an outlet and transmits the signal to the speaker via Bluetooth 5.4 — this is a modern standard with good stability, decent quality and minimal sound delays.
