Lightweight Replacement Headset for Sennheiser Wireless Systems
The MiCWL B40 Black Dual Ear-Hook Headset Microphone is the perfect lightweight upgrade or replacement for your Sennheiser wireless bodypack transmitter with a 3.5mm locking input. Built around an omnidirectional condenser capsule, it captures your voice with sparkling clarity from every angle, free from handling noise or interference. The ultralight dual ear-hook frame provides a secure, shake‑free fit that stays put during performances, presentations, and high‑energy classes, yet folds flat in seconds for easy storage—no protective case required. A soft, flexible cable connects to your bodypack without tugging or restricting your movement, while the discreet beige finish virtually disappears against the skin. Whether you're replacing a worn Sennheiser lavalier, upgrading your headset, or equipping an entire theatre or worship team, the B40 delivers professional, plosive‑free sound right out of the box, complete with a foam windscreen.
Key Features of the B40
🔹 Ultralight & Foldable Dual Ear-Hook — All-Day Comfort, Instant Pack-Up
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.
🔹 Omnidirectional Condenser — Clear Sound from Every Angle
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.
🔹 Soft Flexible Cable — Move Without Restriction
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.
🔹 Seamless Sennheiser Integration — Direct 3.5mm Lock Connection
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.
🔹 Discreet Beige & Plosive‑Free Sound
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.
