Helicopter Headsets

Civilian helicopters use a single U-174 plug, sometimes written U-174/U, rather than the two separate plugs found on most fixed-wing general aviation panels. The headsets in this collection ship with that U-174 connector, so they match a standard rotorcraft intercom jack without any adapter or rewiring.

The main difference is the plug. Helicopter headsets use one U-174 connector, while airplane headsets use a twin general aviation plug. Internally the audio and microphone electronics are similar, so many models are sold in both versions, and only the cable termination changes to fit the panel.

Yes, but only with the right adapter. A dual-plug general aviation headset will not fit a U-174 helicopter jack on its own. You can add a GA-to-U174 adapter, found in our headset adapters and aircraft intercoms collection, or simply buy the headset in its factory helicopter configuration.

Helicopters differ in two ways that matter for headsets. Their intercoms use the single U-174 plug standard, and their cabins are loud, with rotor, transmission, and gearbox noise often passing 100 decibels. That combination is why rotorcraft pilots choose a U-174 headset with strong active noise reduction for both clear communication and hearing protection.

No. The U-174 plug carries audio and microphone signals, but it does not supply power to the active noise reduction or Bluetooth electronics. Those features run on the headset's own battery, which is why the Bose A30 U-174 model in this collection is listed as battery powered with Bluetooth.

It depends on your priorities. The Bose A30 U-174 is the comfort and noise-cancellation pick, with around-ear fit, three ANR modes, and Bluetooth. The Lightspeed Zulu 4 U-174 is the strong value choice with capable active noise reduction. Both ship rotorcraft-ready, so compare comfort and budget, then click for price.
