Got a set of Ear Gear covers just over a week ago and was amazed at the difference. I do a lot of work gardening work in the summer and my hearing aids were constantly giving me warning signals and then eventually stopped working. I'd have to take them out and let them sit for an hour or more to get them to work. Since I put Ear Gear on I have not had any problems at all. In fact now the batteries seem to be lasting a little longer.
