ULTRA Quiet Kit For Earcups

The ULTRA® Quiet Kit installs in your helmet’s earcups to provides passive noise isolation and increased communication intelligibility.  It is a popular alternative to the standard foam installed in helmet earcups.

The kit consists of four die-cut viscoelastic memory foam layers and two cloth/foam top layers that are easily installed in your earcups.

The ULTRA Quiet Kit fits flight helmets and most aviation headset passive ear cups.  They can be used in helmets with earphones or communications earplugs.  They are not needed for helmets with Active Noise Reduction (ANR).
