Number 3. The #taotronics #Bluetooth transmitter. This allows me to convert anything that can has a 3.5mm output, into a Bluetooth audio output device. Amazing because the tv is not built with Bluetooth in it. So I connect this transmitter with an adapter to the tv and connect my Bluetooth headset to it. With the audio quality, I don’t need #subtitles!!! And I can watch a noisy movie in the night without waking up the child or wife. Also also. It transmits to two devices at a time!!!
