MicW is a microphone brand based in Beijing, China, operating as the music and recording arm of BSWA Technology, an acoustic measurement company founded in 1998 as a joint venture involving the Chinese Academy of Sciences. The company's engineering roots in precision measurement microphones carry over into its audio line, where specifications and consistency across units are emphasized over vintage-voiced character.

The catalog is organized into several series: the N-Series of nickel-diaphragm condensers (including small-diaphragm models like the N101 reviewed in Sound on Sound), the T-Series of titanium-diaphragm large-diaphragm condensers, the M-Series of measurement microphones, the L-Series of lavaliers, and headworn models such as the H825. The i-Series targets mobile and action-camera recording, with products like the iGoMic stereo microphone for GoPro cameras and the iShotgun Lightning microphone for iOS devices.

MicW's microphones are used across voice, instrument, broadcast, film, and video production, and are distributed through retailers including Adorama and specialist pro-audio dealers. The brand is less visible in mainstream music production than legacy microphone makers, occupying a niche alongside other measurement-derived condenser lines that appeal to location recordists, field recordists, and mobile content creators.
