What is it?

An advanced sleep tracking headband with smart companion app to monitor sleep quality and instruct on how it can be improved without resorting to pharmaceuticals.

Good points?

The Dreem 2 is a serious piece of equipment with dual front and rear laboratory level electroencephalogram (EEG) sensors that capture brain activity.

These signals are passed to the smartphone app which interprets the data and provides a detailed report on your sleep quality and patterns.

Utilising an array of impressive technologies, such as pulse oximetry which measures oxygen levels and sonometry to determine densities, the device can make intuitive recommendations and offers personalised sleep-restructuring exercises.

Placing and fitting the headband is easy thanks to the three size adjusters. It doesn't feel uncomfortable to sleep while wearing, but does take some getting used to. The battery lasts for 12 hours which should encompass most people's sleep duration.

Music can be played through the bone conducting system to calm you or simply proffer a buffer to any external noises that could impact you drifting off.

Bad points?

This device is on the expensive side and likely to largely attract those with significant sleep problems rather than the occasional insomniac. A visit to the GP should always be the first port of call.

Best for ...

Those possessing the curiosity and disposable income to want to delve into their nightly sleep habits – or a lack thereof.

Avoid if ...

A simple tracker with sleep quality and length metrics will suffice. The Dreem 2 is great but in most cases it's simply overkill.

Score: 9/10.
