The Sennheiser e 935 is a cardioid vocal stage microphone specially designed to perform under pressure while cutting through the mix with its high output. The e 935's cardioid design effectively rejects off axis noise and feedback while an integral hum compensation coil minimizes hum caused by electrical current, bad grounds etc.
Its 40-16,000Hz frequency response is tailored for vocal use and the neodymium capsule withstands extreme sound pressure levels.
