Yeah I know the use case for this is super small probably, but it still sucks. I often sleep with one ear bud in my ear and the other ear pressed up against the pillow and my Sony ear buds allow ANC to work with just one. The ANC works really well with the other ear smothered in the pillow. These won’t work that way so it kinda sucks, you have to have both in your ears or it won’t activate. Hopefully they can update it.
