Designed for use with insert earphones

Disposable

By directly coupling to the test subject’s ear canal via the disposable 3A EARtone Foam Eartips, the Insert Earphone offers audiometric testing that helps provide both performance and reliability advantages over traditional supra aural earphones. Some of these benefits include improved ambient noise attenuation, greater interaural attenuation, facilitated infection control (via disposable eartips), the elimination of collapsed canal artifact, better test/re-test reliability, and reduced occlusion effect for BC testing.
