Why use quick release / disconnect? Reduce radio repair by eliminating the need to repeatedly connect your earpiece directly to the radio. Narrow down an earpiece issue to the adapter or wire, and save yourself from buying a whole new earpiece. Quickly remove your earpiece during a struggle. Easily disconnect your audio accessory when using the restroom. Switch accessories for any environment. Save money during a radio upgrade by purchasing a new adapter instead of an entire kit.
