vt403waVT403 HI-SPL Waterproof Ultra-Miniature Omni Lavalier

The VT403WA is an ultra-miniature Hi-SPL and waterproof lavalier microphone. Fitted with a special subminiature microphone capsule, the VT403WA has high electromagnetic interference protection, very low inherent noise and a low distortion for high sound pressure levels (up to 136 dB SPL). It boasts an ultra-reinforced cable against sweat, cuts and tearing. The cable is 50% stronger than our standard cable. Also allows for temporary submergence (up to 1 meter) of the microphone without compromise and particularly suitable for demanding applications such as punishing day-to-day stage performances, sports & rental houses.
