TV COMPATIBILITY

The Avantree HT41866-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 HT41866-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 HT41866-Q earbuds can pair directly via Bluetooth. In this case, slide the transmitter to 'OFF' because there is no need to use the transmitter.

SHARE THE TV AUDIO

Connect the transmitter to your TV and listen through both headphones simultaneously, each with built-in volume controls so you can listen at your preferred volumes.

POWERED BY QUALCOMM

With its advanced Qualcomm chipset, the HT41866-Q delivers clearer sound, stable connections, and perfectly synced audio & visual – all backed by Avantree's 20+ years of Bluetooth expertise.

NO LIP-SYNC DELAY

With "aptX adaptive" Bluetooth built-in, the HT41866-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.

INDIVIDUAL VOLUME CONTROL, LONG PLAYTIMES

The HT41866-Q’s in-ear earbuds allow each user to adjust its own volume independently. Individuals experiencing hearing can turn up their volume and not disturb their partner or friend watching TV. When fully charged, provide up to 20 hours of playtime, longer than most competitors in-ear models.
