ABSTRACT:
Embodiments disclose a non-roll foam EarTip that may provide for fingertip press-in insertion, improved comfort, simplicity of use, flatter attenuation and/or improved hygienic properties, by way of non-exclusive example. A hollow foam body typically encompasses a shorter stem of more rigid material, and in some embodiments the foam body has a tighter skin on the inner and outer surfaces. In some embodiment, the EarTip is an earplug formed of polyurethane foam with a dense skin on the inner and outer surfaces of the hollow body, and having a plurality of splines in the cavity.
