Built-in carbon monoxide detector
The Lightspeed Delta Zulu is the first headset with a built-in carbon monoxide detector and alerting system. It works right out of the box. Use the free Lightspeed app (for iOS devices) to get historical CO trends or adjust alert levels to suit your preferences.
Rugged construction
Delta Zulu is built to last, with a rugged stainless steel headband, tangle-free cables wrapped in Kevlar, and an unmatched seven year warranty. Thoughtful design choices abound, including a control box where both cables come out the top and a crush-proof carrying case.
HearingEQity™
Based on results from a custom 12-frequency hearing test in the new Lightspeed app, HearingEQity automatically adjusts the Lightspeed Delta Zulu to optimize every ATC call and conversation specifically for your individual hearing profile.
Full Bluetooth features
As you would expect with a premium ANR headset, Delta Zulu has complete Bluetooth integration. Listen to music in flight (a passenger favorite) or make phone calls on the ground and enjoy the headset's noise cancellation to make everything clearer.
Flexible power options
Keeping your Delta Zulu powered is easy with the standard rechargeable battery pack. This slim battery lasts for 30 hours and can be recharged in flight via a portable power bank from a battery pack or cigarette lighter plug (sold separately).
Custom audio profiles
Lightspeed has always offered some of the finest audio quality of any aviation headset, especially when listening to music, but it's even better on Delta Zulu. Use the Lightspeed app to complete a one-time hearing test and the headset's new Hearing EQity.
Lightspeed's best ANR yet
While Delta Zulu might look like an upgraded Zulu 3, under the hood everything is new. It uses additional microphones and dual processors to create Lightspeed's quietest headset yet. You'll be able to understand air traffic control more easily and arrive at your destination less fatigued.
