AF7 looks Good. AF8 is very bed. T9 and TP10 are ok, but need improvement.

You want very flat lines, like here: https://mind-monitor.com/img/mm-screen-3.jpg

@James,
It can depend also on the zoom done in the view, this is the same signal but zoomed with 2 fingers ? :

True. Then I reclarify my remark to be at the default zoom level of 400uV
You can reset this default in "Settings" -> "Vertical Max (Microvolts)".

Great thank you

so is this a problem with my MUSE? I have had less than six months. Or is there a way to fix this?

This is possible or some interference, you should open a ticket on Muse support, they will guide you

I have been able to test 2 Muse S POD, and I'm getting a different result for the same headband N°1 or N°2, one POD has more amplitude in the EEG signal than the other.
So product can differ already on their own and I know the first Muse S match more Sleep staging along Dreem2 than the other.

So I'm pretty sure that sleep staging algorithm can be wrong because of this and not only because of interference !
