Retevis HK008 Active Amplified Speaker Mic (Kenwood 2-Pin)

Overpower the Engine Noise.

Most standard speaker microphones rely entirely on the radio's internal audio circuitry to drive the speaker. When you are operating heavy machinery, riding an ATV, or working on a noisy job site, that passive audio just isn't loud enough. The Retevis HK008 Active Speaker Mic solves this problem by acting as its own independent sound system.

Inside the mic casing sits an active power amplifier and a removable 890mAh lithium battery. This design actively boosts the incoming audio signal, delivering incredibly crisp and loud volume directly to your shoulder. You can even control the volume right from the microphone itself, meaning you never have to unclip your radio to turn up the sound.
