Description

TT042 Sound Amplifier Device Bone Conduction Receiving Earphone

1. Dual-mode listening, covering a wider range of users 

Supports both sound pickup amplification mode and line-in amplification mode, allowing for flexible switching based on different usage scenarios.
Sound pickup amplification mode: Enhances ambient sound, suitable for people requiring hearing assistance and those with mild hearing loss;


Line-in mode: Provides stable sound amplification through wired connection, covering people with hearing impairment ranging from mild to moderate hearing loss. 

2. Bone conduction amplification for more comfortable long-term wear 

Utilizes bone conduction technology to transmit sound to the auditory system through bone vibration, avoiding the direct stimulation of the ear canal and eardrum caused by traditional in-ear acoustic amplification.
More comfortable for long-term wear in lectures, meetings, and guided tours, helping to reduce ear canal discomfort and auditory fatigue. 

3. High gain, low distortion, clearer voice

Achieves a stable gain of 25–35dB in line-in mode, with distortion less than 0.5%, effectively improving voice clarity and intelligibility, ensuring that lectures, presentations, and meeting content are heard clearly and for extended periods.

4. Non-in-ear design, easy to wear in multiple scenarios

Ear-hook bone conduction structure, non-in-ear design, lightweight (approximately 32g), no pressure even with prolonged use, suitable for classrooms, meetings, guided tours, and business communication.

5. Strong compatibility, easy connection to presentation systems

Uses a 3.5mm audio interface, which can be connected to the receiver of the presentation system via a Type-C to 3.5mm audio cable, compatible with many RETEKESS presentation system products (except the TT126 series), facilitating systematic deployment and use.

6. Stable battery life, meeting all-day usage needs

Built-in 200mAh lithium battery, approximately 6 hours of battery life, Type-C charging interface, fully charged in about 2.5 hours, meeting the continuous use needs of daily lectures, meetings, and guided tours.
