Description
 Insert earphones, also known as insert earbuds or intra-aural earphones, offer several advantages over supra-aural (over-the-ear) earphones when it comes to conducting hearing tests. These advantages contribute to enhanced test reliability and can help minimize or eliminate problems commonly encountered with supra-aural earphones. The E-A-R TONE Insert Earphone’s direct coupling to the ear canal also provides greater sound separation between ears across the test frequency range.
