The Sennheiser e 908 B ew is a specialized, miniature condenser clip-on microphone designed for wireless operation as part of Sennheiser's evolution wireless G4 series. It is specifically tailored for close-miking brass and woodwind instruments, featuring a hypercardioid polar pattern that provides focused pickup from the front while offering strong rejection of ambient noise and other instruments on stage. Its compact, low-profile design allows it to be discreetly clipped onto the bell of a saxophone, trumpet, trombone, or similar instrument without interfering with the musician's performance. The microphone connects directly to a compatible evolution wireless G4 bodypack transmitter via a proprietary locking connector, ensuring a secure and reliable link.

The microphone's frequency response is carefully shaped to capture the full tonal character of brass and woodwinds, from the warm fundamentals to the bright harmonics and key noise, with clarity and detail. It requires phantom power supplied by the bodypack transmitter. The included mounting hardware is designed for quick and stable attachment to various instrument shapes. By providing a high-quality, wireless solution for challenging-to-mike instruments, the e 908 B ew enables musicians to move freely on stage while ensuring their sound is captured with exceptional fidelity and minimal feedback risk.

This microphone is a critical tool for live sound engineers and musicians in theater pits, big bands, and touring ensembles, offering a reliable and sonically superior alternative to bulky stand-mounted microphones for brass and woodwind amplification.
