Sheepdog earmolds, or open-ear inserts, are designed for use on two-way radio acoustic tube style surveillance earpieces, listen only earpieces and lapel mics. Earmolds do not block the ear canal and are more comfortable than standard mushroom eartips when working extended shifts. Instead of blocking the ear, earmolds allow for ambient sound to enter. The result is that users are able to copy radio traffic and still their surroundings at the same time. This creates a higher level of situational awareness and increases safety for the officer, agent or soldier. Worn by thousands of police officers and military, earmolds have become a standard for those who operate in law enforcement and/or tactical environments. Earmolds are compatible with all brands of radio earpieces: Motorola, Kenwood, EF Johnson, Harris, M/A-Com, Vertex, Tait, HYT, Hytera, Icom.
