Clean and maintain the OTC Self-fitting Hearing Aids

Make sure to regularly clean your OTC Self-fitting hearing aids to prevent wax and residue build-up on the microphones, sleeves, and wax guards, which can cause the sound to become muffled or low. Use the provided brush or cleaning cloth for daily cleaning to wipe away any visible wax or residue from:

• The case.
• The hearing aids and the microphone holes: Use the cleaning cloth to wipe the hearing aids and gently brush around the microphones to remove any wax build-up daily.
  
  

  CRE-C10

  

  CRE-E10

  

  CRE-C20

• The sleeves: Use the supplied brush or cleaning cloth to wipe the outside of the sleeve and loosen wax build-up or other debris from the tiny holes at the tip of the sleeves.

Give them an occasional deep cleaning

It's great to clean your hearing aids daily, but it's also important to give them a deeper cleaning sometimes to get rid of any buildup inside the sleeves. Along with the supplied cleaning tools, you can also use hearing aid cleaning wipes like AudioWipes to wipe away any visible wax or residue from the hearing aids, sleeves, and case.

1. Remove the sleeves and look for wax build-up on the outside and inside. We suggest holding the sleeve to a light and examining the tiny holes at the tip.
2. Use the cleaning cloth, brush, or recommended hearing aid wipes to remove visible wax or residue.
3. Attach the sleeves to the hearing aids.

Replace the sleeves and wax guards periodically

The sleeves and wax guards on your hearing aids should be replaced periodically to help maintain sound quality and performance. How often you need to replace them depends on factors such as earwax buildup and normal wear and tear, but we recommend replacing them at least every 3 months or whenever you notice a decline in sound quality.

Replacement sleeves are available for purchase through the Hearing Shop and are compatible with Sony-branded and Connexx-branded replacements. Sleeves are available in 4 sizes (XS, S, M, and L), and each package contains 3 pairs. Be sure to select the correct size for your hearing aid.
