Professional audio, microphones and system integration

The Harmonai CM-310E is a professional desktop condenser microphone designed for conference and voice recording applications. Featuring a back-electret condenser capsule, it offers three interchangeable polar pattern capsules — cardioid, supercardioid, and omnidirectional — to meet diverse pickup distance and acoustic environment requirements. With a frequency response of 40Hz–16kHz, its flat midrange and slightly elevated high frequencies ensure clear, bright, and naturally accurate vocal reproduction. Its compact, precision-engineered metal body features a soft-touch matte finish, delivering both durability and refined aesthetics. Powered by standard 48V phantom power and equipped with a gold-plated XLRM 3-pin male output connector, the CM-310E is ideal for conference room speaking, remote video conferencing, podcasting, and broadcast voice work.
