At Dreem, the signal is king!
For the headband to work properly, it is important that each sensor is perfectly positioned so that they can track your brain activity. Here are some good practices so that positioning has no secrets for you.
1. Choose the right size for your headband. M size is put by default but you can switch to S or L size. We recommend you use the Smaller size as it fits most of our users. If the headband is too tight, you can then move on to M or even L size.
2. Place back sensors as far as possible between your hair, in contact with your skin. They are key for classifying your sleep staging.
3. Place the front part of the headband (the thinner part) against your forehead (so it’s touching your skin). Make sure there is no hair between your forehead and the front band.
4. Lift your top arch in order to improve the overall fit.
Verify signal quality with LIVE EEG
Live EEG is located in headband settings. To use it, make sure that you are paired. It measures the difference between brain activity in the forehead and in the back of your head. If well adjusted, you will get a stable signal with a low amplitude.
You can verify good positioning by following Check good positioning with LIVE EEG.
Headband too loose?
Even using the small size adjuster, your headband can feel a little bit lose, or even move during the night.
Here are a couple of tips that can help you if you are in that case:
1. Cross the elastics inside the spacer. It should increase the snug.
