Review on Enhanced Bluetooth 5.0 Transmitter and Receiver with Microphone: EWIN 3-in-1 Low Latency Wireless Audio Adapter for TV, Home Sound System, Car, Nintendo Switch by Marcus Munoz

This bluetooth transmitter is very easy to pair with my headphones and works very well - there is no time lag between audio and TV or laptop video. Bluetooth connection and transmits about 36 feet. Highly visible power, pairing, volume and TX/RX control buttons. I was happy to learn that my TV remote controls the headphone volume so I don't have to go to the transmitter to adjust settings. I've only used it as an audio transmitter so far, so I can't comment on how it works as a receiver or connects a cellphone to a car's audio system. I expect it to work just as well in those situations as it does as a transmitter. It's worth the price!
