Ohma is a microphone manufacturer based in East Los Angeles, founded by a team of designers and builders with backgrounds at AEA Ribbon Mics, Bock Audio, Universal Audio, and Soyuz. The company is built around a modular concept: its microphones use interchangeable screen sets that change both the visual finish and the sonic character of the mic, letting users reshape the frequency response without swapping the whole unit.

The brand's core lineup centers on the Motif platform, available in both ribbon and condenser versions, alongside a range of custom screen sets and finish options. Capsules are made in-house, ribbons are hand-wired, and bodies are painted locally, with each mic tuned and inspected before it leaves the shop. A "Build Your Ohma" configurator and special-order program extend the customization concept into the buying experience.

Ohma is an LGBTQ-owned, majority POC-led company that has been covered by publications including Tape Op, Recording Magazine, and MusicTech, who have highlighted its modular approach as a departure from the traditionally fixed designs of studio ribbon and condenser microphones.

Ohma has 10 products cataloged on Equipboard, including Condenser Microphones and Ribbon Microphones. Their gear is featured by 1 artist, with the strongest followings in Pop, Hip Hop, and Funk / Soul. Notable users include Janelle Monáe.
