ProGuard Earportz eartips have a uniquely pre-formed, ear-canal shape, to direct the sound from earphones deeper into the ear, towards the ear drums, consequently improving definition. Their soft, medical-grade, silicone-rubber material, together with their unique ear-canal shape, makes earphones comfortable even after wearing for long periods of time. The design's three annular micro-filaments reduces ingress of ambient sounds, as well as helping to keep the earphones securely in place, allowing free movement, with a lower tendency for them to fall out.
They are designed to fit in-ear earphones with an audio outlet of between 2mm and 5mm diameter. They are available in four sizes - small, medium, large and extra large.
