The product is designed so that the sounds are not noticed during sleep. The volume is calibrated so that it should not wake you up. To verify that the headband is working, you can view the connection status in your app at any time during use and your Sleep Boost time the next morning.
Alternatively, you can also press the power button for one second to hear the connection tone – a “happy sound sequence” and confirm that it is connected correctly.
If you have tried the advice above but your headband is still not working then please contact us for further help.
