Hollyland Solidcom M1 Pro-4 Single Ear Headsets

Professional 4-user full-duplex wireless intercom with dual-mic ENC, 400 m range, flexible group communication and expandable cascade connectivity for clear, stable team coordination in demanding production environments.

Hollyland Solidcom M1 Pro is the next-generation evolution of the widely adopted M1 wireless intercom platform, delivering substantial improvements in communication clarity, RF stability and system scalability. The M1 Pro-4 Single-Ear configuration provides reliable full-duplex wireless communication for four users with lightweight single-ear ENC headsets that preserve environmental awareness — ideal for camera operators, floor managers and technical crew.

The most important advancement in the M1 Pro generation is dual-microphone Environmental Noise Cancellation (ENC). A supercardioid primary microphone captures the user’s voice while a secondary omnidirectional microphone samples ambient noise. Real-time ENC processing inside the beltpack removes environmental noise, delivering significantly clearer and more intelligible speech than the original Solidcom M1 — especially in loud environments such as stages, sports events and broadcast venues.

RF performance and deployment flexibility have also been upgraded. M1 Pro supports both built-in panel antennas and external fiberglass antennas, enabling optimized coverage up to 400 m line-of-sight. Automatic frequency hopping in the license-free 1.9 GHz band continuously avoids interference, ensuring stable communication even in congested RF conditions — a key reliability improvement over earlier systems.

The Pro platform introduces structured group communication with up to three independent groups and eight preset modes, plus IP and 4-wire cascade connectivity for virtually unlimited base-station expansion — capabilities not available in the original M1 architecture. Combined with improved ergonomics, extended battery runtime and flexible configuration via base station, web interface or Hollyvox app, Solidcom M1 Pro-4 Single-Ear delivers a powerful and scalable professional wireless intercom solution.
