Intelligent intervention enables you to enjoy quiet and healthy sleep every night

Smart Electronic Muscle Stimulator Pro (new type), combined with high-precision sensor and patented algorithm, can accurately identify apnea events

and snoring. With AI, it can produce electric pulse intervention, so that you will restore smooth breathing, stop snoring and get more protection for healthy sleep.

Suitable for individuals with sleep apnea syndrome

Snoring is not a manifestation of sound sleep, but a noise made when the respiratory tract becomes narrow and the air flow passes through the narrow part due to muscle collapse during sleep.

Medically, snoring is the main clinical manifestation of sleep apnea syndrome. Laboratory test results show that the application of Smart Electronic Muscle Stimulator Pro (YA4300)

can effectively prevent apnea, stop snoring, and increase blood oxygen, so that you can enjoy healthy sleep every night.

How It Works

ith a built-in professional medical sensor,it can intelligently monitor the skin surface movement and snoring data.

By using the independent research and development of AI algorithm,

it can accurately identify the movement and send out medium frequency pulses for intervention,

so as to make the throat muscles contract, restore normal breathing,

improve the blood oxygen volume, and enable you to stop or reduce snoring and sleep healthily.

When a apnea event occurs,
the respiratory tract of
the user's throat is narrowed

After the intervention,
the muscle tension of throat will be improved
and the breathing will be smooth

Prevention of apnea; healthy sleep management

Sleep health study is upgraded again. In order to prevent sleep apnea events, it combines the built-in high-precision sensor + patented

intelligent algorithm to intelligently identify sleep breathing, blood oxygen and other information. With the help of multi parameter judgment,

it can monitor sleep apnea events for intervention and maintain healthy sleep.

AI identifies your snoring better than you do

Combined with built-in high-precision sensor + patented intelligent algorithm,

it has 40 fixed and 8 dynamic machine learning models to form your own unique snoring model;

with automatic comparison,it can improve snoring recognition accuracy and significantly improve snoring solution success rate.

Double pulse automatic intervention allows you to breathe easily

It uses TENS + EMA double pulse technology to automatically implement the intervention from weak to strong

according to the user's own situation; by improving the muscle tension of throat,

nd restoring smooth breathing, it let you unconsciously stop or reduce snoring, apnea and get healthy sleep.

Stop snoring and enjoy healthy sleep

noring is a sign of sleep apnea, which will not only reduce your partner's sleep quality,but also affect your health.

It can safely stimulate the muscles under the chin with EMA + TENS technology so as to quickly and effectively relieve your snoring and obstructive apnea

Enjoy a sound and quiet sleep, so that you are refreshed and energetic after waking up!


Use with the YZFTools app. By monitoring your breathing, snoring and intervention, it will track and analyze your sleep health

and form a professional sleep report; parameters such as intervention intensity can also be set according to your own preferences.
