Engineered to be extremely lightweight, the B40’s dual ear-hook design distributes pressure evenly, so you barely feel it even after hours of wear. The frame folds into a tiny bundle in seconds—toss it in your pocket or bag, no protective carrying case needed.
The premium omnidirectional mic element picks up your voice evenly in a full 360° pattern. Your audio stays consistent whether you look left, right, down at notes, or move dynamically—no more volume dropouts.
The ultra‑thin, highly flexible wire is designed to eliminate tugging and cable memory. Connect to your Sennheiser 3.5mm lock bodypack and enjoy complete freedom of movement—ideal for dancing, fitness coaching, and active stage performances.
The B40 terminates in a standard Sennheiser 3.5mm locking plug and is compatible with EW100 G1‑G4, SK100, SK300, and other transmitters using a locking 3.5mm input. It’s a direct, affordable replacement for original Sennheiser lavalier and headset microphones.
The black color keeps the microphone unobtrusive on stage and camera. The included foam windscreen suppresses breath pops and wind noise, ensuring your voice comes through polished and professional in any environment.
