David Clark 40583G-02 – H3441 Pushback Tug Headset

The H3441 Pushback Tug Headset is designed for high-noise communication environments, such as aircraft pushback, ramp, towing, and industrial vehicle operations. Its single-ear, behind-the-head style makes it ideal for users wearing helmets or hard hats, while still allowing them to hear ambient sound for safety awareness.

The H3441 uses a single, noise-attenuating earcup with a vented dome on the opposite side, allowing the operator to hear external sounds. In contrast, the H3442 has two fully sealed earcups for maximum noise reduction. This makes the H3441 a better choice for operations where situational awareness is as vital as communication clarity.

Yes. The H3441 is compatible with David Clark Series 3100, 3400, and 3800 intercom systems, as well as Series 3000 mobile radio adapters, making it suitable for both wired and vehicle-mounted communication setups.

The H3441 features a David Clark M-7A electret, noise-canceling microphone, which provides clear, distortion-free transmission in high-noise environments. The microphone is mounted on a hybrid wire-flex boom that rotates 280°, allowing for placement on either the left or right side, depending on user preference.

The behind-the-head design should rest comfortably below protective headgear, with the adjustable overhead strap providing stability. Ensure the gel-filled ear seal fully encloses the ear for best audio isolation and comfort. The reversible spring assembly allows the microphone boom to switch sides easily, accommodating both left- and right-handed users.

The H3441 comes equipped with a 6-foot coiled communication cord that terminates in a 1/4" stereo plug (PJ-051), the standard connection for Series 3000 adapters and vehicle intercom stations. The heavy-duty, shielded cord resists radio-frequency and electromagnetic interference (RFI/EMI) for clear, uninterrupted communication.

Because the H3441 is a single-ear model, it is not rated with a formal Noise Reduction Rating (NRR). However, the single sealed earcup still provides effective sound attenuation, while the open dome design on the opposite side helps maintain awareness of external activity on the ramp or vehicle deck.

Built from ABS composite domes and a carbon-steel spring assembly, the H3441 is engineered for rugged, all-weather performance. Components such as the gel ear seals, switch guard, and strain-relieved cord are designed to withstand vibration, temperature extremes, and physical handling typical of heavy-duty ground operations.

Yes. The H3441’s modular construction allows for replacement of key components, including the microphone, cord assembly, ear seals, and overhead strap. Replacement parts are clearly identified in the official H3441 parts list, which simplifies maintenance and minimizes downtime.

The H3441 is especially suited for pushback tug drivers, ramp crew, and vehicle operators who must maintain communication while staying alert to surrounding activity. Its hybrid design balances clear two-way communication with the ability to hear critical ambient sounds such as engine cues or personnel commands.

The push-button on/off switch built into the earcup allows operators to instantly mute the microphone when not transmitting, reducing background noise on shared intercom channels. This simple yet effective control improves communication discipline during multi-crew operations.

Yes. The H3441 connects seamlessly to the Series 3800 Vehicle Intercom System, which supports up to four personnel per vehicle and allows both radio and intercom communication. This integration enables clear communication between drivers, pump-panel operators, and command personnel, even in noisy or wet environments.

Regular maintenance includes wiping down ear seals with a damp cloth, checking connectors for debris or corrosion, and storing the headset in a dry environment. For long-term care, replacing worn ear seals and microphone covers annually helps preserve comfort and clarity in demanding use conditions.

The behind-the-head configuration allows the H3441 to be worn comfortably under helmets or hard hats, which is not always possible with traditional over-the-head models. This ergonomic advantage makes it ideal for ramp personnel, military ground crews, and industrial operators who require both safety gear and reliable communication simultaneously.
