Product Description

The Avantree HT41866 is a set consisting of two (2) Bluetooth 5.0 in-ear headphones and a transmitter. The wireless transmitter is Bluetooth Class 1, and both in-ear headphones are factory pre-paired and offer no lip-sync delay and personalized audio control. Enjoy TV with a partner or friend!

Compatible with 99% of TVs

The Avantree HT41866 uses the AudikastPlus wireless transmitter and includes Optical, AUX, and RCA input cables. It’s compatible with any TV that has a working Audio Output jack. It is the perfect Bluetooth set for non-smart and smart TV brands and arguably better than the Bluetooth built into your TV. The Audikast transmitter works with Vizio, Samsung, LG, Sony, TCL, Phillips, Hisense, and more

Two Headphones, at the Same Time

The Dual Link feature allows audio to be played through both pairs of wireless headphones simultaneously, with perfect audio. However, either headphone can function independently in case only one person is watching TV. Your partner or friend can join you at any time without any audio interruption for you. Simply have them press the neckband’s power button when ready to watch, and the headphone will automatically connect.

No Lip-sync Delay

Certified Qualcomm aptX Low Latency, the Avantree HT41866 Audikast Plus transmitter provides <40 ms audio latency. Typical solutions in the market can have audio latency over 100MS or more which causes the notorious “Bluetooth audio lag” experience where the images on the TV and the audio are off. Its low latency design delivers perfectly synchronized visual & audio no matter what you’re watching.

Individual Volume Control

We all hear differently, and the volume level that works for you might not work for your friend or partner. The HT41866 set solves this issue by allowing you to adjust each in-ear headphone’s volume independently, letting you avoid remote wrestling or clashes over the volume level. Those individuals experiencing hearing can now increase their volume levels without affecting their partners’ TV experience.

Headache-Free Pairing

The dual neckband in-ear headphones and Bluetooth transmitter are factory pre-paired making the connection procedure painless. No more making sure the device is in Bluetooth mode or setting both device and headphones to find each other. Just power on the transmitter and headphones, and they will automatically connect – every time.

Which helps keep your ear tips elevated and free of dust and other particles.

Use with Other Devices

The two in-ear headphones and the Audikast Plus Bluetooth transmitter that make up the Avantree HT41866 kit can be used independently. Operate the in-ear headphones as regular Bluetooth 5.0 headphones for your cell phone, tablet, laptop, or computer. While the Class 1 Bluetooth 5.0 transmitter can send audio through an external speaker (like a soundbar or AV receiver + speakers) of another brand.

Powerful, Lightweight, & Comfortable

The headphones last up to 20 hours when 100% charged, more than enough for a full day of binge-watching. The lightweight and ergonomically designed neckband is complimented by the soft earbuds, delivering all-day comfort without the weight and pressure of over-the-ear headphones.
