This compact remote speaker microphone has a revolutionary windporting feature that helps lessen background noise from high winds and other severe weather conditions. Audio can pass through the speaker grill even when the microphone port is blocked by water. This mic includes a 3.5mm accessory jack to accommodate an optional earpiece (AARLN4885 sold separately). The coiled cord allows talking and listening without removal from belt or case. Includes Push-to-talk switch, swivel clip and quick disconnect latch.
