The NC-1 Noise Cancelling Headset is engineered for amateur radio operators who require
clear, high-intelligibility audio in noisy contest and DX environments. Designed for long operating sessions,
the NC-1 delivers excellent ambient noise reduction and comfortable monitoring performance whether used in the
shack, at a multi-op station, or during remote operations.

The NC-1 headset is sold without a microphone. Optional boom microphones are available
separately. This modular approach ensures maximum flexibility while maintaining economic values for no-voice operations.

Key Features

• Advanced noise reduction: reduces ambient shack and background noise for cleaner monitoring and improved weak-signal reception.
• Optional boom microphones: microphone modules are not included and must be ordered separately.
• Comfort for extended use: lightweight design, padded adjustable headband, and soft ear cushions minimize fatigue during long operating sessions.
• Rugged build: durable frame and reinforced cable strain reliefs for contest and portable use.
• Excellent passive isolation: closed-ear design helps block external noise and enhances signal focus.
• Flexible microphone system: accepts supported detachable boom mic modules for tailored transmit audio performance.
• High compatibility: works with most HF transceivers when paired with the appropriate microphone module and cable; adapters available for FlexRadio, Icom, Kenwood, Yaesu, and others.
• Ideal for SO2R: comfortable, noise-isolating design suited for high-rate dual-radio setups.

Use Cases

• Contest stations requiring clear reception and fatigue-free audio monitoring.
• DXpeditions needing lightweight, durable headsets with excellent noise isolation.
• Remote operators who depend on consistent audio performance in varying environments.
• SO2R contesting where isolation and comfort are critical for maintaining concentration.
• General HF operation benefiting from lower ambient noise and improved operator focus.

Quality, Engineering, and Reliability

The NC-1 is built using high-quality acoustic components and durable mechanical parts designed for continuous
operation. Its ergonomic structure reduces pressure points, ensuring comfort during long contests or DX sessions.

When paired with an appropriate optional microphone module, the NC-1 delivers excellent transmit audio tailored
for contest and DX performance. Its modular mic system ensures long-term flexibility and easy replacement or upgrades.
