The Lindy 3.5mm & TosLink (Optical) Audio Bluetooth Transceiver is a compact, multi-function solution for connecting non-Bluetooth devices wirelessly to sources and outputs with Bluetooth connectivity. 3.5mm and TosLink (Optical) input ports allow for the connection of non-BT source devices such as TVs, amplifiers and laptops, this transceiver can then transmit a high-quality audio signal wirelessly to Bluetooth headsets, soundbars or speaker setups.
