Ear Gear Original Hearing Aid Comfort, Protection and Security Clip – Fits Hearing Instruments 1.25” to 2” – Secure Your Hearing Aid or Amplifier– Protect From Sweat, Dirt, Moisture, Loss & Wind Noise

Work great for water protection. Doesn't affect the sound quality

I love these! Yes they are a little expensive but well made and lovely bright colour. Would defo but again.

the cover is ok for the battery and clarity when its windy. I had hoped for some cover for the plastic laying in the ear shelf. to save scratching irritating.

Seems to be well put together. Time will tell how it performs behind sweaty ears. Can't work out though why they're so expensive

Item is fine but price is a joke. In UK should be less than £20 including postage. Google is your friend.
