Product Description

Hollyland HL-Solidcom M1 Pro-4B 1.9 GHz Full-Duplex Wireless Intercom System

Overview

Meet the Hollyland Solidcom M1 Pro, a wireless intercom system designed with one intention: to help teams communicate clearly, no matter where the job takes them. From the first moment you power it on, the difference is unmistakable. Conversations feel natural. Voices sound true. When the world around you gets loud, the M1 Pro puts your team's dialog front and center. Its dual-mic Environmental Noise Cancellation technology elevates clarity to a professional standard, cutting through loud stages, bustling sidelines, and energetic production floors with precision. Voices stay crisp, focused, and clean.

Built with comfort in mind, the newly designed ergonomic headsets offer a secure, natural fit you'll appreciate when the day gets long. Every contour is crafted for stability in motion while reducing fatigue. Whether you prefer the single-ear (this version) or dual-ear style (DH version), both deliver superior audio quality and exceptional noise reduction, backed by a full set of field-replaceable accessories to keep hygiene and maintenance simple.

With an impressive 1,300-foot line of sight range, the Solidcom M1 Pro enables teams to easily synchronize across small to medium-size rooms. Dual-antenna architecture includes built-in panel and external fiberglass antennas to reinforce stability even in complex environments.

What about the future? Scalability is where the Solidcom M1 Pro truly shines. Connect two base stations through IP or 4-wire cascade, or combine both methods to create an expansive communication network (additional components sold separately) with virtually no limits. As you grow, so grows your system, intuitively, and without complexity.

Plan, coordinate, communicate. Nail it with Solidcom M1 Pro.
