Good Sound. Great Range - My wife and I have different ideas about what an appropriate volume for watching television is. She has a pair of JBL Bluetooth headphones and I have a pair of VOKALEN Hyper Pros. I like this device because you're free to use what you've got and aren't locked into a brand of headphones you don't like. I split the AUX out of the TV to go to our soundbar and to this device so we can use both. Setup was really as easy as putting the headphones in pairing mode and pressing the button on the device; They find each other easily. The audio is clean and stable and I was a little surprised at the range. I didn't think it would go as far as it does. And the device is smaller than I expected too so it's easy to find a place to put it. Review: Easy connection - I’ve used this to connect Bose headphones to an older LG TV. It works very well. Easy connection to the optical port on the TV and the headphones picked up immediately. Sound quality for watching TV is good. No lag. ## Features - 【WORKS WITH OPTICAL & AUX TVs】This Bluetooth transmitter works with TVs that have Optical (TOSLINK) or 3.5mm AUX audio output, sending TV audio wirelessly to Bluetooth headphones or speakers for private TV listening. - 【WATCH TV WITH TWO HEADPHONES】Connect two Bluetooth headphones simultaneously from one transmitter and enjoy TV together. Supports aptX-Adaptive for high-quality audio and reduced delay with compatible headphones. - 【BUILT-IN VOLUME CONTROL】Adjust volume directly on the transmitter using the built-in volume control buttons, especially helpful when TV remote volume control is unavailable due to fixed audio output. - 【NOT FOR HDMI-ONLY TVs】Not compatible with TVs that have HDMI-only audio output, as this product works via Optical or AUX connections only. - 【LIMITATION / IMPORTANT NOTES】When using Optical output, the TV audio setting must be set to PCM. Bluetooth headphones must be placed into pairing mode to connect successfully ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DK8TC1WJ | | Additional Features | 1. aptX-Adaptive Support; 2.
