The M-003-A ANR Adapter is a product that will transform a current aviation flight helmet into a high-tech active noise reduction unit. The ANR Adapter comes as a kit and will fit all SPH-3, 4, and 5, as well as HGU-33, HGU-55, HGU-84, PRK-37, HGU-56, and all military style helmets.
Earcups with earseals are required for installation into aviation helmets. Included with this kit is one pair of silicone gel type ear seals that will fit most helmet earcups.
Really easy install with the provided instructions, they have changed the new units to include a disconnect point. This is prewired to you’re not soldering on the unit itself anymore - which is a common failure point before they did this. If you have basic soldering skills you can do this. I’ll come back and edit my review when they fail.
