3.5mm Noise Cancelling Headset Extension Cable with U174U Helicopter Plug, Professional Aviation Gaming Headphone Audio Extension Cord, Anti-Interference Low-Noise Transmission Wire for Flight Helmet

This professional 3.5mm headset extension cable is matched with U174U aviation plugs, specially made for helicopter flight helmet communication and gaming headset audio extension use. The built-in multi-layer noise cancelling shielding effectively cuts engine electromagnetic interference and ambient static, ensuring clear, distortion-free voice and stereo audio transmission during flight tasks and long-hour gaming.

High-purity oxygen-free copper wire cores greatly reduce signal attenuation, maintaining stable high-fidelity audio output. All connectors are reinforced with strain relief molding to avoid wire fracture caused by repeated plugging and movement inside cockpits or gaming desktops. The flexible outer casing resists wear and twisting for long-term daily use.

It supports two-way stereo audio transmission, compatible with most aviation intercom equipment, PC gaming headsets and audio playback devices. No complicated setup or driver installation required, simply plug and extend audio signals. Widely suitable for helicopter pilots, flight trainees, aviation staff and desktop gaming players needing long-distance headset audio extension.
