Hollyland Solidcom C1 Pro-5S Full-Duplex ENC Wireless Intercom System with 5 Headsets (1.9 GHz)

Hollyland Solidcom C1 Pro-5S Full-Duplex ENC Wireless Intercom System

The Hollyland Solidcom C1 Pro-5S is a professional-grade, full-duplex wireless intercom system designed for seamless team communication in challenging, loud production environments. Operating on the secure, license-free 1.9 GHz frequency band with advanced DECT 6.0 technology, this configuration includes five true-wireless single-ear headsets (one Master and four Remotes).

By embedding the transceivers directly into the lightweight headset frames, it entirely eliminates the need for bodypacks, messy cables, or an external base station hub for standard operation.

1. Advanced Dual-Mic Environmental Noise Cancellation (ENC)

The defining feature of the Solidcom C1 Pro series is its acoustic isolation layer, engineered to handle chaotic field environments like live concerts, sports arenas, or busy film sets:

• Dual-Microphone Intel: Each headset features a primary directional electret microphone that captures the speaker's vocal range with precision. Simultaneously, a secondary omnidirectional microphone on the outer ear cup records ambient environmental noise.

• Real-Time DSP Filtering: An advanced internal algorithm processes both feeds, scrubbing away up to 20 dB of background noise (such as screaming crowds, heavy machinery, or wind shear).

• Wideband Audio Clarity: Operating within a wide 150 Hz to 7 kHz frequency response range with a high 71 dB Signal-to-Noise Ratio (SNR), the system prioritizes vocal presence and details while maintaining less than 1% distortion.

2. Workflow Control & Push-to-Talk (PTT) Dynamics

The C1 Pro features an updated mechanical interface built on user feedback from previous generations to allow instant, tactile communication adjustments on the move:

• Dedicated PTT Button: Located directly on the ear cup is an ergonomic Push-to-Talk / Mute button. A long press activates standard PTT functionality (talk when pressed, mute when released), while a simple short click toggles the headset between continuous "Talk" and "Mute" modes.

• Flip-to-Mute Microphone Boom: Users can also control their active state by moving the microphone boom. Raising the boom arm vertically triggers a physical mechanical switch that silences the channel instantly, while pulling it down past the mouth line reactivates the mic link in milliseconds. An integrated LED light on the tip of the mic provides immediate status confirmation.

3. Extended Wireless Stability & Backward Compatibility

• 350-Meter Line-of-Sight Range: The master headset acts as the routing core for the system, anchoring a stable, bi-directional communication cell over a 350-meter line-of-sight (LOS) radius.

• Dual-Antenna Design Scheme: Each headset houses a pair of internal antennas to combat polarization fade and shield the network against RF interference, ensuring consistent signal performance as crew members move throughout a venue.

• Ecosystem Backward Compatibility: The C1 Pro headsets are completely backward-compatible with the original (non-Pro) Solidcom C1 series. Production teams can mix and match components seamlessly to expand their existing intercom fleets.

4. Ergonomic Durability & Split Battery Lifecycles

• Ultra-Lightweight Comfort: Crafted from highly resilient, impact-resistant PC-ABS composite materials, each individual headset weighs an ultra-light 170 grams (with the battery included), preventing neck strain and fatigue during marathon production shifts.

• Swappable Power Cells: The kit utilizes removable, hot-swappable 700 mAh Lithium-Ion battery packs. Because the Master headset functions as the structural routing link for the entire 5-person loop, it manages higher power demands:

  • Remote Headsets: Up to 10 hours of continuous uptime with active ENC engaged.

  • Master Headset: Up to 5 hours of continuous uptime when supporting all 4 Remotes concurrently.

• Fast Multi-Slot Charging Base: The package bundles an external, dedicated high-speed desktop charging hub capable of completely replenishing depleted batteries in approximately 2.5 hours.

Technical Summary

• Ecosystem Configuration: 5-Person Hubless Framework (1x Master Single-Ear Headset, 4x Remote Single-Ear Headsets).

• Wireless Protocol: Digital DECT 6.0 Spectrum (1.9 GHz Band / GFSK Modulation).

• Operational Boundary: Up to 350 meters line-of-sight threshold.

• Acoustic Performance Passband: 150 Hz to 7 kHz; Signal-to-Noise Ratio 71 dB; Max Input Tolerance of 115 dB SPL.

• Active Noise Suppression Depth: Dual-Mic ENC reducing up to 20 dB of omnidirectional floor noise.

• Materials & Portability: Structural PC-ABS frame; Net weight of 170 grams per unit.

• System Power Management: 700 mAh Li-ion rechargeable cell; 2.5-hour recharge threshold.

• Box Contents: 1x C1 Pro Master Headset, 4x C1 Pro Remote Headsets, 10x Rechargeable Lithium-Ion Batteries, 1x Multi-Slot Battery Charger Base, 1x DC Power Adapter, 5x Over-Ear Leather Cushions, 5x On-Ear Foam Cushions, 5x Foam Microphone Windscreens, 1x USB-A to USB-C Cable, Hard-Shell Specialized Carry Case.

The Hollyland Solidcom C1 Pro-5S delivers an exceptionally clean, responsive, and reliable wireless network for 5-person media crews. By integrating heavy-duty 20 dB active noise cancellation, flexible PTT ear cup controls, and bodypack-free ergonomics into a rugged hard case, it provides production teams with the precise, hands-free coordination needed to call complex live-action cues flawlessly.
