Features and benefits of Lightspeed Zulu H-Mod

Noise reduction and acoustic clarity - Enjoy fatigue reduction and clearer communications enabling you to focus on flying and the mission at hand.

Engineered for comfort - Plush ear seals with abundant surface area are designed for comfort on long duty days, even while wearing glasses.

Bluetooth connectivity - Connect your cell phone or iPad. Enjoy excellent call clarity, music fidelity, and wireless access to critical audio alerts from aviation apps on mobile devices.

ComPriority™ - Never miss important radio communications with patented ComPriority, which lowers the volume of any auxiliary device automatically during radio or intercom transmissions.

Auto Shutoff™ - Lightspeed's propietary Auto Shutoff feature saves battery life by automatically shutting down the power when not in use.

Quick disconnect cable - More convenient egress with Lightspeed's exclusive detachable cable system. This quick disconnect has a 9-pound pull force (4 kg) and makes emergency egress even safer. Quick disconnect cables are recommended by the NTSB.

Kevlar reinforced cable system - Stronger and more flexible than standard cables, these rugged cables have proven themselves for durability, stay out of the way, and weigh less than traditional or coiled options.

Plugs - Plug options include LEMO, U-174 for helicopters, and general aviation plugs for any helicopter or fixed-wing aircraft. 

Zulu H-Mod Engineering - H-Mod has been engineered by Lightspeed. It is not a headset that has been taken apart. It can be installed in your existing helmet or included in a new one.

Helmets - Zulu H-Mod is available for HGU-55/P, HGU-55/E, HGU-68/P, HGU-84/P, and other helmets without lateral impact attenuation requirements. It cannot be installed in HGU-56/P or SPH-5 helmets, which have energy-absorbing earcup requirements.

3-year warranty - Zulu H-Mod is backed by a three-year factory warranty.

Gentex's HGU-84/P is approved by the US Department of the Interior and the US Forest Service for use in helicopters. The HGU-55/P, HGU-55/E, and HGU-68/P are approved for use in fixed-wing aircraft.
