About this item

  • [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 Avantree 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. Avantree Aria) for the best no-audio-lag experience. (Note: Audio may become off sync if you use a non-FastStream device).

Frequently Asked Questions:

Q: My TV speakers go silent (become muted) when I use the Avantree Bluetooth transmitter. Can I make them work simultaneously while using the transmitter?

A: This is a TV feature and its availability depends on your TV make and model.

For many models of TV, the built-in speakers might not work if you choose to use an external speaker. They will either automatically mute when you plug something into an audio output port (AUX, RCA, Optical, etc.) or they become disabled once you choose "External Speakers" as your TV's audio output. Some newer TVs however, allow you to play audio from both the TV's internal speakers and an external audio device simultaneously. For example the newer LG TVs with WebOS versions 3.0 and 3.5 have this feature but Samsung TVs still do not. In the LG TV WebOS 3.0 / 3.5 example, you can enable this feature by changing the TV AUDIO OUT setting from "Internal TV Speaker" to “Internal TV Speaker + Optical”. Now all audio will simultaneously come from both your TV's speakers and the device connected to the digital optical audio output port.

If your TV does not support this feature, then you can consider the Avantree HT5009 / HT5006 and an external speaker. The Avantree Oasis Plus transmitter has a convenient bypass feature which allows you to share the TV audio simultaneously with an EXTERNAL SPEAKER and a pair of Bluetooth headphones.

    Headphones very tiny charging port
    Problem solved and they are suggesting clearer instructions for us old eyes... And I love it again! This worked wonderfully for the first day. then it just said "Power Off" and died. I did the troubleshooting with tech on line and they said send it back. I did. But never got the promised replacement. I bought another this one died the same exact way during the first use. I paid duties and shipping on two units. It cost me $9.50 to mail the first unit back. The pre paid postage is *not international. I have a Sony Smart TV bought in Costa Rica and Variable electric power protected by a surge protector. I was very careful to fully charge the second unit. WHAT AM I DOING WRONG? earphones really help hear when it is raining hard here in the Costa Rican Rain Forest. So after this published customer service said charge the HEADPHONES! I kept charging the transmitter Because these old eyes could not see the port. AND the directions could have been clearer....
