The TT042 bone conduction headset offers long-lasting comfort. Its 200mAh battery supports 8 hours of continuous operation, easily meeting daily usage needs.

The smooth surface of this soft silicone amplifier resists the accumulation of dust, sweat, and sebum—unlike fabric or foam alternatives. For users who wear hearing devices for extended periods (especially in summer), a quick wipe with a soft, damp cloth easily removes most sweat and everyday stains.

Compatible with mobile phones, tablets, tour guide systems, and radios. Simply connect the headset via the Type-C interface to any device with a 3.5mm jack to amplify audio—whether it’s news, music, podcasts, or other content.

Made from soft, flexible material that contours to your ears and head, the device does not require insertion into the ear canal. It stays secure without falling off, accommodates glasses wearers comfortably, and maintains ear canal hygiene.

Multi-level adjustment within the 25–35 dB range allows for precise control, ensuring the sound delivered is at a comfortable volume for you.

Blue indicates power on; red indicates charging; gray indicates power off or fully charged. These clear, simple indicators prevent wasted power and unnecessary charging, optimizing your user experience.

Intuitive volume control, physical buttons, clear color indicators, a plug-and-play Type-C interface, and broad compatibility make it easy for first-time users to operate without training.

Offers a standard sound amplification mode as well as an option to connect to external devices for audio amplification. For instance, Retekess tour guide systems—such as the T130 series and TT116—ensure a clear audio experience even in noisy environments like tourist attractions, museums, or busy streets, provided the speaker uses the accompanying transmitter.
