Point Source Audio is a microphone and headset manufacturer based in Petaluma, California, founded in 2004 by James Lamb and Yvonne Ho. The company designs and assembles miniature microphones for theatre, broadcast, houses of worship, and live performance, with a focus on durability, modular construction, and discreet on-body wear. Its product lines include the SERIES8 family of headset, earset, earworn, and lavalier mics, the EMBRACE on-ear lavalier, the SERIES9 line, and the CONFIDENCE (CO2) dual-element microphones, which place two capsules in a single body for built-in redundancy.

The company also makes the CM-i3 modular in-ear intercom headset, which uses interchangeable earphones and was the basis for one of its earliest patents. Point Source Audio mics are commonly specified for stage musicals and have been adopted as standard equipment by institutions including Berklee College of Music, with use cases extending into TV production and broadcast.

Point Source Audio has 13 products cataloged on Equipboard, including Wireless Microphones, Headphones & In-Ear Monitors, and Clips & Mounts.
