The MiCWL B40 Black Dual Ear-Hook Headset Microphone is the perfect lightweight upgrade or replacement for your MIPRO wireless bodypack transmitter with a Mini TA4F 4‑pin lock input. Built around an omnidirectional condenser capsule, it captures your voice with sparkling clarity from every angle, free from handling noise or interference.

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 .
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 .
The ultra‑thin, highly flexible wire is designed to eliminate tugging and cable memory. Connect to your MIPRO Mini TA4F bodypack and enjoy complete freedom of movement – ideal for dancing, fitness coaching, and active stage performances.
The B40 terminates in a standard MIPRO Mini TA4F 4‑pin locking plug and is compatible with ACT‑series (ACT‑32/52/72 etc.), ACT‑8 series, and other MIPRO transmitters using a TA4F lock input. It’s a direct, affordable replacement for original MIPRO lavalier and headset microphones.
The Black 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.
