  • Bluetooth– Bluetooth wireless technology with A2DP technology enables cell phone communications and stereo music streaming along with alerts from aviation apps.
  • Low-profile comfort– Weighing just 14.9 ounces (including ear seals, head pad and mic boom), Delta Zulu has a low-profile, stainless-steel headband that follows the curve of the head for more comfortable distribution of weight and side pressure.
  • High-performance fit– Delta Zulu’s tapered performance ear seals are designed to hug the curve of the jaw for a natural fit, increasing comfort and clarity while also providing a better seal around eyeglass or sunglass frames. Cup cavities allow the entire ear to fit comfortably inside.
  • Durability and longevity– Made almost entirely of stainless steel and magnesium with durable cables built around a Kevlar core, Delta Zulu is designed to endure the harshest flying environments and last for years to come.
  • Superior quiet– Delta Zulu delivers advanced active noise reduction (ANR) performance over a deep, broad range of low-frequency noise. The magnesium ear cups are superior at blocking out high-frequency noise.
  • Clear comms– The Dual Aperture Disc microphone provides greater noise cancellation for clearer, more intelligible communications. Exclusive, user-adjustable mic gain helps balance loud and soft voices in a multi-headset environment.
  • ComPriority™– Never miss important radio communications with patented ComPriority, which automatically lowers the volume of any auxiliary device during radio or intercom transmissions. The soft mute feature gently eases music back in for a smooth listening transition.
  • Auto Shutoff™– Lightspeed’s proprietary Auto Shutoff feature saves battery life by automatically shutting down the headset power when not in use.
  • Included accessories– Carrying case, single port wall charger, lithium-ion battery cartridge, AA battery cartridge, UAC to USB-A cable, a cord shirt clip, and a set of personalized icon chips to distinguish multiple headsets.
