This week, Zeo has stopped recording data after about 1.5 - 2 hrs into the night. I've have previously worn the head band for 2-3 weeks without any major issues. The first data drop was this week - followed by two good nigts of recording, then another night of data stopping to be recorded after about 1.5 hours of sleep. I already had imprints on my fore head from the head band so it's not an issue of the head band being too loose. However, a friend suggested that he had a similiar problem and tightening the band resolved his issue. I attemtped that the following night with a tightned head band. I woke up around 3:30 am with discomfort from the head band so I took it off. The next morning I checked the data and it had stopped collecting a few hours before I had taken the band off.
What are your suggestions?
