Oto Blocks | Ear Dams

Our standard foam oto blocks / foam ear dams are an industry standard due to their wide application range from tiny ear canal to large ear canal, these foam oto blocks / foam ear dams will fit most impression applications.

We also have shorter versions in the same sizes as well as vented versions for pressure release.
