Why The Wellness recommends this

Curated, not stocked.

Our team selected the FRENZ Brainband for its genuinely distinct approach to sleep support — the combination of real-time brainwave tracking and adaptive CBT audio delivery sets it apart from passive wearables that log data without acting on it. It earns its place in our technology category on the strength of its clinical study programme and the specificity of its mechanism, not its novelty as a gadget. For those navigating persistent sleep difficulty who want a structured, evidence-informed tool rather than another supplement, this is a considered starting point.

About this product

Frenz Brainband sleep wearable

The FRENZ Brainband, developed by Earable Neuroscience, is positioned as the first AI sleep wearable designed to both monitor and actively stimulate brain activity. Rather than passively logging sleep data, it uses built-in bone-conduction speakers to deliver personalised Cognitive Behavioural Therapy audio sessions that adapt in real time to your brainwave patterns as you transition into sleep — a meaningful distinction from standard sleep trackers.

Worn as a headband, the device is designed to fit all adult head sizes and accommodate a range of sleep positions, which matters for a wearable intended for nightly use. It operates in conjunction with the FRENZ app, which handles real-time sleep scoring and manages your personalised audio therapy programme. The app is currently compatible with iOS only; an iPhone 10 or newer is required for full functionality.

By night, the Brainband is designed to help you fall asleep faster and sleep more deeply. By day, it supports focus and cognitive performance through dedicated in-app sessions. The device has been clinically studied, with findings indicating it can help users fall asleep faster, sleep more deeply, and wake feeling more refreshed.

This product is best suited to people for whom sleep difficulty is a consistent, low-grade problem rather than an acute one — those who lie awake with a busy mind, wake frequently, or find that poor sleep compounds into daytime cognitive fatigue. It sits within a broader sleep hygiene routine rather than replacing one.

Please note: the FRENZ app is currently iOS only and is not supported on Android. A compatible iPhone and the FRENZ app are required for full device functionality.

How to use

Wear the headband at bedtime. Open the FRENZ app on a compatible iOS device (iPhone 10 or newer) to begin a personalised audio therapy session.

For daytime focus support, follow the dedicated in-app guidance.

Common questions

Frequently asked

Is the FRENZ Brainband safe to use if I have a pacemaker or other implanted medical device?

The Brainband uses low-power sensors and bone-conduction audio, but we advise checking with your cardiologist or device manufacturer before nightly use, as individual implant protocols vary.

How long will it take before I notice an improvement in my sleep?

In the published clinical study most participants saw a measurable reduction in time-to-sleep and an increase in deep-sleep duration within the first seven nights of consistent use.

Can I wear the Brainband if I sleep on my side or stomach?

Yes. The soft, flexible headband is designed to remain comfortable and maintain sensor contact in side, back or stomach sleeping positions.

Does the device work without the app or an internet connection?

No. Real-time brainwave processing and personalised audio delivery require a connected iPhone 10 or newer running the FRENZ app; the headband cannot store or play sessions independently.

Will the bone-conduction speakers disturb my partner?

Bone-conduction audio is directed into your inner ear and remains largely inaudible to someone lying next to you at normal bedroom volumes.
