Key Features
Effortless Operation
The product eliminates the need for complex Bluetooth settings or pairing. Users can simply turn on the headset’s power to immediately enjoy wireless TV audio. This intuitive design ensures ease of use for individuals who may be unfamiliar with technical operations or for elderly users, providing a stress-free audio experience for the entire family.

Smart Charging and Integrated Transmitter
The transmitter unit serves a dual purpose as both a charging cradle for the headset and an audio transmitter. When not in use, the headset can be placed on the transmitter for charging, removing the need for cable connections. This integrated design simplifies daily routines and reduces clutter.

Open-Ear Design for Situational Awareness
Featuring an open-ear design, the earphones allow users to enjoy TV audio without blocking out ambient sounds. This ensures that conversations with family, the doorbell, or other environmental noises remain audible, enhancing safety and convenience, especially during nighttime viewing or for individuals living alone.

Low Latency for Synchronized Audio
Through proprietary IC tuning, the earphones achieve a low latency of approximately 50ms, even with the SBC codec. This minimal delay ensures that video and audio are closely synchronized, providing a comfortable viewing experience for news, dramas, and movies without noticeable audio-visual discrepancies.

Broad Compatibility
The 400-BTAD014 supports 3.5mm, optical digital, and RCA (red/white) terminals, making it compatible with a wide range of old and new televisions and audio equipment. The product includes all necessary cables, allowing users to start using it immediately after purchase. It is suitable for use in living rooms and for “listening on the go” in different areas of the home.

Beyond TV: Smartphone Connectivity
In addition to TV use, the headset can also connect to Bluetooth-enabled devices such as smartphones, tablets, and laptops. This expands its utility beyond just television, offering versatility for various audio needs. When connecting to a Bluetooth device, the transmitter’s power should be turned off.
