As the owner of three first gen Echos and a Dot, I've noticed that the volume ring on the Echos has become very "erratic" in controlling volume manually (i.e. it goes from 2 to 10 with the slightest of movements and visa versa). I'm sure they were never that sensitive/erratic when I first owned them. I wondered if any other users experience the same issue and is there a cure, or a way to re calibrate?
Any hints, tips, help would be gratefully appreciated
