Phenyx Pro is a professional audio equipment company headquartered in the San Diego, California area, operated by Phenyx Technology LLC. Founded in the mid-2010s, the brand focuses on accessibly priced wireless gear for live performance, houses of worship, public speaking, karaoke, and small-venue PA work, positioning itself as a value-oriented alternative to higher-end wireless brands.

The company's catalog is organized around a few core product families: UHF wireless microphone systems (including the PTU-5000, PTU-6000, PTU-7000, PTU-71, and the true-diversity PTU-1U series), in-ear monitor systems (such as the PTM-10 and PTM-33), wireless instrument systems for guitar and bass, antenna distribution and combiner units like the PAS-225X and PAS-227X, and the PTL series of audio mixers. Most of their wireless systems are sold in dual, quad, and eight-channel handheld and bodypack configurations.

Phenyx Pro operates as both a manufacturer and brand, selling direct through its own site as well as Amazon, Reverb, and authorized dealers, and runs community-facing programs including beta testing groups, an affiliate program, and dealer partnerships. It is generally known among hobbyists, worship teams, and budget-conscious gigging musicians rather than touring professionals.
