“cheero Otocarti LINK” Neckband Cartilage Conduction Hearing Aid Launched
TRA Co., Ltd. (Headquarters: Osaka, Representative Director: Toru Azuma) launched the neckband cartilage conduction hearing aid “cheero Otocarti LINK” on January 14, 2026, at noon.

“Otocarti LINK” is a neckband-type cartilage conduction hearing aid that makes necessary voices easier to hear. It begins amplifying sound immediately upon power-on, with a simple design that only requires volume adjustment. It offers up to 20 hours of continuous use, making it suitable for all-day wear during work or outings. This device aims to reduce listening stress by making conversations clearer in workplaces, hospitals, government offices, and daily interactions with family.

Product Features
Extremely Simple Operation
Designed for ease of use, even for those unfamiliar with digital devices. Simply turn on the power to start sound amplification, then adjust the volume. (Note: It does not have Bluetooth functionality.)

Significantly Suppresses Howling
The design separates the sound collection microphone and the earphones, effectively suppressing uncomfortable howling (feedback noise).

Proprietary Technology for Loud and Clear Voices
Proprietary equalizing technology suppresses unwanted noise and clearly emphasizes speech. A high-performance chip ensures ambient sounds are also heard clearly, making conversations and TV watching more comfortable.
Ear-Friendly Cartilage Conduction
The earphones are worn by lightly resting them in the hollow of the ear, rather than inserting them into the ear canal. This provides comfortable wear for long periods without pain or stuffiness. It also minimizes the sound of one’s own chewing, making TV and conversation sounds easier to hear.

Neckband Type Prevents Loss
Designed to be worn around the neck, there is no worry of it falling off even while walking. When not in use, the earphones can be removed and kept around the neck, ready for immediate use.

Easy to Clean, Always Hygienic
The spherical earphone parts have no uneven surfaces, preventing earwax buildup. They can be easily wiped clean, ensuring constant hygiene.
IP65 Dust and Water Resistance
Designed for ease of use in daily situations, such as light rain or during household chores where water may splash.
Rechargeable and Eco-Friendly
Provides up to 20 hours of use on a single charge. Rechargeable batteries eliminate the need for disposable batteries. The charging port is USB-C.
Quality and Support from a Japanese Manufacturer
This product is planned and quality-controlled by TRA Co., Ltd., a Japanese manufacturer. After-sales service is provided by a dedicated domestic support center in Japanese (available via phone and email), offering peace of mind for first-time hearing aid users.


“Otocarti” earphones (cartilage conduction vibrators) utilize patented technology from CCH Sound Co., Ltd.
About Cartilage Conduction
Cartilage conduction is often mistakenly believed to be a type of bone conduction, but its hearing mechanism, sound transmission properties, and characteristics are entirely different from bone conduction. When the earphone part (cartilage conduction vibrator) vibrates the ear cartilage, sound is created within the external auditory canal. This sound then travels through the eardrum and middle ear to the cochlea. It differs from air conduction in that the sound source is created within the external auditory canal, and it differs from bone conduction in that it does not require bone vibration.
