1. I'm a restless sleeper and I would like an earpiece that cuts out all sound. Does such an earpiece exist? (A.) Yes. An Hearingtech SleepFit surpresses all the surrounding noise. The SleepFit is made of soft silicone that is also comfortable to wear at night. 2. What is the best way of cleaning my earpiece? (A.) Clean it with a damp cloth and then dry it with a soft cloth. Cleaning tablets or Hearingtech cleaning spray is another good option.
