David Clark H10-13S Headset Parts Guide & Illustrated Catalog

The David Clark H10-13S headset parts guide covers everything you need to maintain and service this stereo-capable GA headset — from OEM replacement components to comfort upgrades that extend wearability on long flights. Built on the proven H10-13 platform, the H10-13S adds one standout feature to an already trusted design: a stereo/mono switch that lets you receive two discrete audio channels when your avionics panel supports it. That single addition makes it a natural fit for pilots flying behind modern glass or stereo-capable intercoms.

Like every headset in David Clark's lineup, the H10-13S is engineered to last — but sustained performance depends on consistent maintenance. Ear seals lose their compliance, microphone elements wear, headband springs fatigue after years of clamping pressure, and cord assemblies absorb punishment across hundreds of flight hours. Knowing which parts to watch, when to swap them, and where to source genuine replacements is what keeps a good headset performing like a new one.
This guide covers the full picture: specs, features, a direct comparison against the H10-13.4, a numbered illustrated parts catalog with OEM part numbers linked to Pilots HQ, comfort upgrade options, and a maintenance checklist. If you're servicing an H10-13S or sourcing parts, everything you need is here.

• Stereo/mono switch: The David Clark H10-13S's defining feature — toggle between full stereo audio from a compatible intercom or panel, or standard mono for any cockpit
• Passive 23 dB NRR protection with no batteries or electronics to fail — the same circumaural geometry that has made the H10-13 family a cockpit standard for decades
• M-7A electret noise-canceling microphone delivers crisp, clear transmissions in high-noise piston and turboprop environments- Dual GA plugs (PJ-055 and PJ-068) work in virtually every fixed-wing GA aircraft with no adapter needed
• Shared H10-13 platform means a large, well-stocked parts ecosystem — ear seals, domes, boom hardware, and headpads are all widely available
• Robust construction built for daily use: stainless steel headband spring, stamped aluminum ear domes, and David Clark's proven cup-to-head seal geometry
• Comfortable weight distribution across the H10-13 frame — balanced enough to wear through a full duty day without neck fatigue
• TSO-C139 and TSO-C57a certified — meets FAA Technical Standard Order requirements for flight training and commercial operations

• Model Number: H10-13S
• Part Number: 40422G-01
• Weight: Approximately 340 g (12 oz)
• Cord: Straight dual GA plug — PJ-055 (mic) and PJ-068 (audio), approximately 5 ft
• Microphone: M-7A electret noise-cancelling, flexible boom
• Passive Noise Reduction Rating (NRR): 23 dB
• Design: Passive circumaural (over-ear) with stereo/mono switch
• Certification: TSO-C139, TSO-C57a

The David Clark H10-13S achieves its 23 dB Noise Reduction Rating through purely passive means — no active circuitry, no battery dependency, nothing electronic to fail or maintain mid-flight. That rating comes directly from the circumaural cup design, which completely surrounds the ear and creates a sealed acoustic chamber. The stamped aluminum dome shells provide a rigid structure that maintains cup geometry under real-world clamping forces, while the foam ear seals press against the sides of the head to close off the path of external sound. In practical cockpit terms, 23 dB NRR is well-matched to most GA piston environments — enough to reduce engine and propwash noise to a manageable level during cruise without the weight or complexity of active noise cancellation.

The variable that most affects real-world noise attenuation is ear seal condition. Compressed, hardened, or cracked seals break the acoustic seal around the ear and can meaningfully reduce actual noise blocking — often well below the rated figure. The foam loses its compliance before it shows visible surface damage, which means pilots frequently fly with degraded protection without realizing it. If your David Clark H10-13S feels louder than it once did, or if the seal around your ears has become inconsistent, fresh ear seals are the first and most cost-effective repair. David Clark lists the Undercut Gel Earseal (pair, part number 40863G-02) as item #9 in the official IPC for this model.

At a glance, the David Clark H10-13S and H10-13.4 are nearly identical — and for maintenance purposes, they largely are. Both headsets share the same H10-13 circumaural platform, the same 23 dB NRR passive protection, the same M-7A electret noise-cancelling microphone, and the same dual GA plug cord. The frame geometry, ear domes, headband spring, headpad, and boom hardware are interchangeable between the two models. If you're sourcing service parts, the distinction between H10-13S and H10-13.4 almost never matters — the parts catalogs overlap almost entirely.

The single point of divergence is audio capability. The H10-13.4 is a mono headset — both ears receive the same audio channel regardless of what the panel sends. The H10-13S adds a stereo/mono toggle that routes separate left and right audio channels to each ear when connected to a stereo-capable intercom or avionics panel. For pilots flying IFR behind modern glass with stereo audio outputs, or in multi-crew environments where audio channel separation is useful, the H10-13S is the right choice. If your cockpit doesn't support stereo output, the toggle stays in mono and both headsets perform identically.

Key comparison:

• H10-13S: Stereo/mono switchable — 23 dB NRR passive, M-7A mic, dual GA plugs, stereo audio capability
• H10-13.4: Mono only — same 23 dB NRR, same M-7A mic, same dual GA plugs, lower price point

👉 If your panel or intercom supports stereo output, the H10-13S is worth the difference. If not, the H10-13.4 delivers identical acoustic performance for less.

Looking to make your David Clark H10-13S even more comfortable on long flights? These two upgrades are customer favorites — both drop in without tools and require no modifications to the headset:

• Replace ear seals every 6–12 months depending on usage and wear — the gel undercut seals (40863G-02) listed in the official IPC are the correct replacement for this model.
• Swap out the headpad if it becomes compressed or uncomfortable — the Headband/Headpad Kit (40688G-36) is listed as item #13 in the parts catalog and drops in without tools.
• Inspect cord assemblies and plugs for stress cracking, fraying, or intermittent audio — the Comm Cord Kit (18028G-81) is the OEM replacement for this model.
• Toggle the stereo/mono switch deliberately at each preflight to keep the contacts clean — one-sided audio is almost always the switch, not the receiver.
• Clean headset surfaces regularly with mild, aviation-safe wipes to remove sweat, sunscreen, and oils that degrade foam and leatherette over time.
• Store your headset in a protective bag or case between flights to prevent UV exposure, dome damage, and mic boom wear.

With consistent care and genuine David Clark OEM parts, an H10-13S will deliver reliable service for a decade or more — most "worn out" headsets just need fresh ear seals and a new headpad.

The H10-13S ships with standard dual GA plugs — PJ-055 for the microphone and PJ-068 for audio — the right configuration for virtually every fixed-wing GA aircraft. If you fly multiple aircraft types or need to adapt to a different panel configuration, the three adapters below keep you connected without swapping headsets.

• GA to Helicopter Adapter (18253G-06): Converts dual GA plugs to a single U-174/U connector for helicopter operations — essential if you split time between fixed-wing and rotary aircraft.
• Airbus XLR Adapter: Adapts the H10-13S for Airbus-style 5-pin XLR jacks found in many turbine and airline training environments.
• GA to LEMO/Bose Adapter: Bridges the standard dual GA plugs to LEMO-style connectors used in select high-end avionics installations.

👉 Keep the GA-to-helicopter adapter in your flight bag if you ever jump into a Robinson or Bell — it weighs nothing, connects in seconds, and means you're never caught without proper audio protection.

Small accessories make a big difference in headset longevity and comfort.
