    The E-A-RLINK™ 3A is a 1/2 inch height Standard/ Adult size (13.7mm) diameter yellow foam disposable/ single-use eartip with black tube for use with the E-A-RTONE™ 3A and 5A Insert Earphone.

    By directly coupling to the test subject's ear canal, via disposable foam E-A-RLINK™ eartips, the E-A-RTONE™ 3A and 5A Insert Earphone for audiometric testing provide both performance and reliability advantages over traditional supra aural earphones. Benefits (in comparison to supra aural/TDH style earphones) include;
    Improved ambient noise attenuation
    Greater interaural attenuation
    Facilitated infection control (via disposable eartips)
    Elimination of collapsed canal artifact
    Better Test/Re-test Reliability
    Reduced Occlusion Effect for BC testing

    Infant Eartips are designed to be used as an alternative for the foam (E A RLINK™ ) eartips connected to the E A RTONE™ Insert Earphone in instances where the smallest (3B) foam tip size is too large for the test subject's ear canal.
