The Hollyland Solidcom C1 Full-Duplex Wireless DECT Single-Ear Master Headset has been engineered to provide clear audio and all-day wearing comfort in a single-ear, true-wireless design with no bodypack or HUB required. Included with the headset are two rechargeable batteries, a mic cushion, an over-ear earmuff, and an on-ear earmuff. This master headset can be paired with up to 5 remote headsets (available separately) without needing a HUB and uses DECT 6.0 encryption and dual antenna technology to ensure secure and reliable transmission at a range of up to 1000'—making it well suited for a variety of applications including film production, concerts, and public events.

True-Wireless Self-Contained Master Headset for 2-Way Communication

With no beltpack or base station, the C1 headset offers a highly portable and hands-free coordinating experience for media production teams and others looking for real-time, non-blocking voice communication in socially distanced working scenarios at distances up to 1000'.

Easy to Use

Pairing with a remote headset (available separately) is quick and simple, and tactile volume buttons allow for fast adjustments—making the system easy to operate. The microphone boom on the headset rotates 360°, allowing for left or right orientation. Rotating the boom arm up or down conveniently mutes the mic when not in use. An LED indicates the system is working and warns you when the battery is low.

Add Remote Headsets, Add HUBs for Larger Systems

The Solidcom C1 system allows you to link up to 5 remote headsets to the master headset without using a HUB. The C1 HUB base (available separately) allows up to 8 headsets to be used at once. Up to 3 hubs can be cascaded with a standard RJ45 cable, allowing for up to 24 headsets to be used at the same time. The HUB also offers additional features including A/B grouping and an announce key that mutes all the headsets for emergency messages from the HUB base.

Two Rechargeable Batteries Included

The headset runs on a single rechargeable battery and a second battery is also provided as a backup to have on hand. The amount of battery time in the master headset depends on the number of following headsets in use; with 5 remote headsets connected, the battery will last for approximately 5 hours; with 3 remote headsets in use, the battery life is 6 hours. The battery fully recharges in 2.5 hours and a battery charging station is available separately.

Wide Frequency Response for Precise Coordination

The Solidcom C1 offers a 150 Hz to 7 kHz frequency response and premium acoustic echo cancellation (AEC) to ensure clear intelligible audio for effective teamwork. The directional mic captures the speaker's voice precisely while minimizing unwanted background sound, making conversations easier even in noisy environments.

Enhanced Stability and Security with DECT 6.0

Built on the powerful DECT 6.0 platform and featuring a dual-antenna diversity scheme, the Solidcom C1 can prevent people outside the system from hearing your conversation with encryption technology and provides stable and reliable transmission with doubled user capacity on the communication channel.
