Who uses a Dreem 2 or a Muse S headband with 4 EEG channels for sleep studies with an accuracy of around 80 percent?

Both devices offer an accuracy of around 80 % which has been shown in scientific papers. You can find those in our journal. This can be compared to the accuracy of a Garmin Forerunner 235 compared to a Quinton Q-tel RMS 3 channel ECG device as you can see in this table:

Which physiologist writes a paper with a Garmin Forerunner 235 as his heart rate measurement device? If a physiologist uses a Dreem 2 headband or a Muse S headband for a sleep study, is it any better? We can choose instead on OpenBCI heatset with up to 16 EEG channels:

091. Low-cost high-quality ECG & EEG devices which offer validation papers

And we suppose the accuracy of this device for sleep studies is much higher.
