Shure RK379 is a replacement kit for SM31FH, with a clip and two foam windscreens.

One thing we’ve seen over the journey, is that any fitness headset usually cops a barrage of sweat and rough treatment.

With any number of instructors swapping headsets, it’s sometimes necessary to replace bits and pieces.

The cable clip in RK379 is designed to help take strain off the headset cable, by securing to your intructor’s clothing.

The two foam windscreens help not only to protect from the wind noise of a heavy breather, but they also increase resistance to water damage, by adding an extra layer of absorbant material between the microphone capsule and the outside world.
