Before each calibration and each session, Muse checks to see if your headband is turned on correctly and is getting a good enough signal using a multi-coloured circle. This step is designed to prevent you from starting a session which will be unresponsive and unpredictable due to an improper headband fit.
Whether you're having trouble getting the colors of the Headband Status Indicator to fill in or your sessions are being interrupted with signal quality problems, there are a few things you can try to find a fit that works for you.
Muse is a sensitive device and it requires good contact with your skin to detect your brain signals. To ensure a good connection, try the following:
1. Ensure your Muse headband is fully charged.
2. Tap the bottom of the signal quality check screen and swipe through and make sure you have followed each of the instructions there.
3. It’s designed to be used while sitting still in a comfortable upright position. We cannot guarantee good signal quality or an accurate experience if you are lying down, in motion, or in any position other than still and upright.
4. Try wearing the headband in advance. Next time, try pairing and connecting your headband to your device, then immediately putting it on your head. That way, the signal will settle while you’re getting comfortable, loading the app and setting up your session.
5. Even if it’s already comfortable, try pulling the earpieces in and out of the forehead band to adjust the headband's size (similar to adjusting a pair of headphones) to see if that helps. Find a sweet spot where you can feel the sensors putting a comfortable amount of pressure against your skin, but not too much pressure. The headband shouldn’t be squeezing your ears forward.
6. If it still doesn't work, try dabbing a touch of water on the headband's sensors can help establish an initial connection.
7. Make sure your skin is clean and the headband is clean where the sensors make contact with your skin. Make-up, or the buildup of natural oils of your skin, can form a barrier that blocks the electrical signals from reaching the sensors. Try wiping your skin with a damp cloth.
8. Ensure you have a good fit with your Muse headband. Adjust the size a few times and try to see if it works. The headband should push the sensors against your skin with a gentle pressure - experimenting with different sizes can help you find the right pressure to use.
9. Make sure there's no hair between the sensors and your skin, especially behind the ears.
10. Keep your eyes closed and relaxed during your calibration to avoid unwanted interference.
11. The headband will not function properly if your app is set to the wrong region setting—make sure the selected region in your app's settings matches where you are right now.
Even after you get the colors filled in, we recommend making a continued effort for the best fit possible. The better signal quality you have, the more accurate and responsive Muse will be.
The following two video tutorials can also help with signal quality:
If you are a regular user, cleaning your Muse headband can also help. From time to time, use a small amount of rubbing alcohol on a cotton swab, and gently rub the forehead band sensors, and silicone earpieces. Make sure not to use too much, just dab the cotton swab and lightly rub the entire surface of your Muse headband. You can wipe the plastic casing and the rest of your headband down with a lightly damp cloth. Mild tarnishing of the silver electrodes is expected and does not impact performance.
