Zeus

Key Benefits

• Clinically shown to reduce snoring frequency and intensity.

• Lightweight, ergonomic, and designed for all-night comfort.

• Rechargeable and portable with 30 free hydrogel pads.

A smarter, clinically proven way to reduce snoring. Zeus is a clinically developed, non-invasive solution for tongue and throat snoring, designed to support the muscles that keep your airway open during sleep.

Developed in collaboration with King’s College London and Guy’s and St Thomas’ NHS Foundation Trust, Zeus uses gentle TENS technology to stimulate the tongue and upper airway muscles. By supporting these muscles throughout the night, Zeus helps maintain airway stability, improve airflow and reduce the vibrations that cause snoring.

The stimulation is delivered in subtle, intermittent pulses designed not to disturb sleep. Once asleep, most users do not feel the sensation, allowing Zeus to work quietly in the background.

The result is deeper, more restorative sleep for you and a quieter, more peaceful night for your partner.

How Zeus works:

During sleep, the muscles of the tongue and throat naturally relax. For many people, this leads to airway narrowing or partial obstruction, which causes snoring.

Zeus delivers low-level electrical stimulation to the upper airway muscles, helping them remain active and in their natural position. This supports an open airway, reduces resistance to airflow and addresses snoring at its source.

User manual

Zeus brings together fifteen years of focused research, engineering, and clinical validation in Transcutaneous Electrical Nerve Stimulation technology. It delivers gentle electrical pulses that stimulate the hypoglossal nerve to improve muscle tone around the airway during sleep. This innovation applies advanced neuromuscular science in a lightweight, silent, and ergonomically designed device. The result is quieter nights and deeper, more restorative rest for you and your partner.

Zeus was born through a 15-year collaboration between engineer Howard Clarke, MBE, and Professor John Moxham of King’s College London. United by a mission to develop a non-invasive, effective solution to snoring, they combined advanced engineering with clinical respiratory research. The result is Zeus—a sleek, UK-developed device that uses transcutaneous electrical nerve stimulation (TENS) to gently activate muscles under the chin, improving airway tone during sleep. Clinically validated and designed for comfort, Zeus represents the next generation of sleep technology—helping you rest better, breathe easier, and wake up refreshed.

Zeus is designed to help reduce snoring caused by:
• Tongue snoring and airway collapse
• Throat snoring due to muscle relaxation
• Airway narrowing during sleep
• Mixed snoring types involving the tongue and upper airway

If you are unsure what type of snorer you are, you can take a snore test or speak to a healthcare professional.

Do not use Zeus if you:
• Have facial hair under the chin that prevents proper adhesion

• Have a pacemaker or implanted medical device

• Are pregnant

• Have epilepsy, heart conditions or a history of DVT

• Have cancer or recent surgery scars on the neck or chin

• Have broken or infected skin on the neck or chin

• Are using another electrical or sleep-related device

Seek medical advice before use if you have severe mental illness, Alzheimer’s, dementia or memory impairment.

If irritation or discomfort occurs, discontinue use and consult a healthcare professional.
