Problems with Oticon Vigo RITE

Has anyone else experienced problems with Oticon VIGO RITE? I purchased these last spring and they are constantly failing. They were replaced but they started failing. Basically, they will short out and will not turn on, or they will sound very tinny. Eventually they come back on. Just curious if any other VIGO users are experiencing any issues?

Can you clarify your response “buy dry and store global” ?

I have seen the same problem due to humidity.
Dry and store, should solve this problem
