HEA 371

The HEA 371 is a professional wired headset designed for high-noise environments such as airport ramps and ground handling operations. It prioritises a robust, hard-wired connection for maximum reliability while delivering clear voice communication in front of loud engines and ground equipment.

HEA 371 offers high acoustic attenuation with SNR 32 dB / NRR 25 dB, compliant with EN352-1 and EN352-6 standards. Its asymmetrical earcup design improves both comfort and acoustic protection during long shifts. The headset uses a waterproof, rotating microphone available in electret or dynamic versions and can be supplied with multiple connector types such as 6.35 mm jack or TP120, plus a coiled cable that extends up to 12 metres for ramp flexibility.

By combining high noise reduction with clear audio, HEA 371 helps protect hearing while keeping communication intelligible in front of running engines and support vehicles. Operators no longer need to shout or rely on hand signals, which reduces errors, stress and fatigue. The ergonomic, asymmetrical design and adjustable headband make the headset comfortable to wear for extended ground handling and MRO operations.

HEA 371 can be configured with Push-To-Talk directly on the headset cup, on the cable or on a chest-mounted switch, so each ground operator can choose the most practical position for their procedures. This flexibility makes it easier to keep hands free for chocks, cones, hoses or tools while maintaining full control over radio transmissions.

Globalsys offers a complete accessory ecosystem for HEA 371, including long and short coiled cables, training Y-cables to connect two wired headsets to the same aircraft intercom, carry bags, and several hygiene and comfort items such as leather protectors, ear rings, hygiene kits and microphone foams. These accessories help adapt the headset to each ramp layout and maintain long-term comfort and hygiene.

HEA 371 is aimed at ground handling & MRO teams: ramp agents, marshallers, mechanics, de-icing crews, towing and pushback operators, as well as industrial users who need reliable wired communication and strong hearing protection. It is particularly suited for airports and service providers who prefer a robust, non-wireless solution or need to complement their wireless systems with wired posts.

The HEA 371 wired headset is trusted by major aviation and ground handling players, including Airbus, Dassault Aviation, Qatar Airways, Swissport, Aviapartner and Luxair, who rely on it to protect their staff and secure voice communication in extreme noise environments.

While Airlink 2085 and 3085 provide full-duplex wireless communication, HEA 371 offers a rugged, wired alternative for positions where a cabled connection is preferred or required. It can be used alone or alongside wireless solutions, giving airports and operators a coherent communication ecosystem that covers both mobile and fixed ground positions with consistent audio quality and hearing protection.
