Does anyone else get that stuffy or blocked feeling while wearing full ear moulds? I also keep finding mine need more adjustment. The right one keeps fading on me. Maybe i need a new one or just an adjustment. How long do warranties last for these? The other thing is it may need a cleaning. I tend to get wax a lot! how's everyone enjoying their hearing aids? Mine are comfortable but my right one pinches sometimes. I think now that my job is going well I can take care of that.
