The UmeCobra is theBoom's two-port noise-cancelling microphone for high-noise cockpits: the front port concentrates your voice, the rear port rejects rotor and engine noise. The US Air Force Research Laboratory measured 82% speech intelligibility at 105 dB against 72% for the M-87. It retrofits standard flight helmets and aviation headsets in under a minute and is flown by military helicopter pilots, hoist operators, rescue divers and flight-line crews. This is the 5 Ω dynamic version on a swivel (rotating) mount: the direct M-87/M-101 replacement for military-standard ICS on HGU-56/P, SPH-4/5, Gentex and Alpha helmets with a rotating boom. Sensitivity −69 dBV/Pa, 50–20,000 Hz, S/N > 70 dB. Choose the standard version or have theBoom's waterproof film fitted — recommended for hoist, SAR, open-door and maritime operations.
