Low Latency Bluetooth 5.0 Dual In-ear Headphones & Transmitter Adapter Set + Stand for Watching TV with Personalized Audio Control

The Avantree HT41866 is two (2) in-ear headphones and a transmitter Bluetooth combo set. The wireless transmitter 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, and when finished, place the Bluetooth headphones on the included stylish standfor convenient storage.

The Avantree HT41866 uses the Audikast Plus 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 builtinto your TV. The Audikast Plus transmitter works with Vizio, Samsung, LG, Sony, TCL, Phillips, Hisense, and more.

The HT41866's Dual-Link feature allows audio to be playedthrough 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 audiointerruption for you. Simply have them press the neckband's power button when ready to watch, and the headphone will automatically connect.

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. HT41866's low latency design guarantees perfectly synchronized visual & audio no matter what you're watching.

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 eachin-ear headphone's volume independently, letting you avoid remote wrestling or clashes over the volume level. Those individuals experiencing a hearing loss (approximately 450 million globally¹) can now increase their volume levels without affecting their partners' TV experience.

HT41866 TV Headphone Set comes with two headphones, the BLACK, and RED headphones.

The BLACK headphone is the primary "1" headphone. It is paired & LOCKED with the transmitter.

The RED headphone is the secondary "2" headphone. It is paired but not locked withthe transmitter. 

NOTE 1:  

Each time when you use the headphones, the BLACK headphonenormally reconnects to the transmitter automatically. But you do need to click the middle silver button on the RED headphone once to reconnect it. Details are as follows:  

1. Turn on BLACK headphones. 

2. Turn on RED headphones.

3. Turn on the transmitter (for 1st-time use) or Turn OFFand BACK on the transmitter(for next-time use).

4. Wait for 3-5s for it to auto-reconnect to the transmitter. IF the RED headphone does NOT connect, you can:

4.1. Wait for 3s and then quickly tap the middle silver button ONCE. You will hear a long beep, and the RED Headphone will announce 'Connected'.

4.2. If the RED headphone failed to reconnect, quickly tap the "2" button onthe transmitter once and WAIT 3-5 seconds. The RED Headphone will announce 'Connected'.

NOTE 2: 

Both headphones now show SOLID BLUE and are well connected to the transmitter. The Bluetooth sign next to "1" and "2" on the transmitter is also both OLID BLUE.

If this is not the case, please turn both devices off andturn them back on again and wait for 5-10 seconds. 

If this does not happen even you tried to turn them both off and on and waited for 5 seconds, you might need to manually Re-pair, Connect, and Lock the headphone and transmitter base again. 

All the Avantree TV headphone sets are all "FACTORY LOCKED" before shipping. This means that as soon as they are turned on, they should automatically re-connect with each other and show Solid Blue on the headphone. NO need to re-pair them each time. 

If they do not show solid blue indicating that are connected, please turn all devices off and turn them back onagain and WAIT for 5-10 seconds. If they still fail to reconnect, please followthe steps below to RECONNECT and LOCK them again.
