Wireless & Streaming Audio HT4186 Wireless Headphones Earbuds for TV Watching, Neckband Earphones Set w/Bluetooth Transmitter for Optical Digital Audio, RCA, 3.5mm Aux Ported TVs, Plug & Play, No Audio Delay

[Hassle-Free Set Up] No need to go through the complex Bluetooth pairing process; simply plug the HT4186’s transmitter into a power source and your TV’s audio output port, power everything on, they’ll quickly connect with each other, and you should be good to go. Works brilliantly with older Non-Smart TVs as well.
[Universally Compatible] Thanks to Wireless & Streaming Audio HT4186’s Optical, AUX, and RCA input cables, it is universally compatible and works with all TVs on the market, smart or non-smart. With it, you’ll be able to listen to your favorite movies at your own volume; you’ll no longer have to turn the speaker volume way up and disturb your family or neighbors.
[No Lip-Sync Delay] With "FastStream" Bluetooth built-in, the HT4186 provides <40 ms audio latency – significantly lower and better than the 200+ ms of typical Bluetooth solutions on the market. With this feature, no matter what content you're watching, the audio and visual will always be perfectly synchronized.
[Use them Separately] Want to use the 4186 earbuds with your phone? No problem! The earbuds are versatile and can function independently without the transmitter. It is designed with precision-engineered 40mm stereo drivers, delivering powerful yet steady audio quality while ensuring a smooth & dynamic listening experience.
[Add a 2nd Headphone] The HT4186 supports dual-link audio and allows you to add a 2nd pair of Bluetooth headphones to it. We highly recommend using a headphone that supports FastStream Bluetooth (e.g. Wireless & Streaming Audio Aria) for the best no-audio-lag experience. (Note: Audio may become off sync if you use a non-FastStream device).
