TV Compatibility

The Avantree HT4186-Q supports TVs with optical (TOSLINK), AUX (3.5mm), RCA input cables or built-in Bluetooth audio outputs. Before purchasing, confirm that your TV has one of these options. With the HT4186-Q, you'll be able to listen to your favorite TV shows & movies at your own volume without disturbing those around you.

Using With Smart TVs

For Smart TVs with built-in Bluetooth (e.g., 2024 Samsung TVs), the HT4186-Q earbuds can pair directly via Bluetooth. In this case, slide the transmitter to 'OFF' because there is no need to use the transmitter.

No Lip-Sync Delay

With "aptX adaptive" Bluetooth built-in, the HT4186-Q provides <50 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.

Powered by Qualcomm

With its advanced Qualcomm chipset, the HT4186-Q delivers clearer sound, stable connections, and perfectly synced audio & visual – all backed by Avantree's 20+ years of Bluetooth expertise.

Boosted Volumes

Transmitters connected via optical sometimes suffer from low volumes that cannot be adjusted; the Audikast 3 can alleviate this by boosting the volume of optical connections by up to 6dB.

Use them Separately

Want to use the 4186-Q 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.
