The 3M E-A-RLINK Foam Eartips (Model 3B, Article 420-2006) are disposable replacement eartips designed for use with the 3M E-A-RTONE 3A and 5A Insert Earphones used in professional audiometric hearing testing. This pack contains 50 individual eartips in the small/pediatric size (3B), finished in beige with a black sound tube attachment.

By directly coupling to the test subject's ear canal via these single-use foam eartips, the E-A-RTONE Insert Earphone system offers significant performance and reliability advantages over traditional supra-aural earphones. Key benefits include improved ambient noise attenuation, greater interaural attenuation, facilitated infection control through the disposable design, elimination of collapsed canal artifact, improved test/retest reliability, and reduced occlusion effect for bone conduction testing.

The 3B small size is suited for pediatric patients and individuals with smaller ear canals. The eartips are made from PVC foam, are latex-free, and feature a cylindrical shape. These are intended for professional audiometric and occupational use only, compatible with the 3M E-A-RTONE 3A and 5A insert earphone models.
