Head to head

The matchups pilots ask us about most.

Delta Zulu · $1,299

  • Carbon monoxide sensor with audible alerts
  • HearingEQity tunes audio to your hearing
  • Rechargeable, with AA backup
VS

Zulu 4 · $1,099

  • Dual Bluetooth: iPad and phone at once
  • Longer mic boom
  • FrameFit seals sit better over sunglasses
Our take: Same frame, cables and 7-year warranty. Pick the Delta Zulu if you fly piston singles with older exhaust systems or already notice some hearing loss. Pick the Zulu 4 if you live on your iPad and phone in the cockpit.

Zulu 3 · $949

  • Magnesium cups, stainless headband
  • Kevlar-reinforced cables
  • 1.4 oz lighter, 7-year warranty
VS

Sierra · $749

  • Full ANR and Bluetooth
  • Lowest price in the line
  • 5-year warranty
Our take: The Sierra is the step up most student pilots take from a passive headset. If you fly more than a few hours a month, the Zulu 3 is the one that lasts.

Lightspeed Zulu 4 / Delta Zulu

  • Zulu 4: $200 less, dual Bluetooth
  • Delta Zulu: CO detection at the same price
  • 7-year warranty on both
VS

Bose A30 · $1,299

  • Lightest here at 14.2 oz
  • Three noise-cancelling modes
  • Side-swappable mic, 5-year warranty
Our take: Against the A30, the Zulu 4 gives you dual Bluetooth and two more years of warranty for $200 less, and the Delta Zulu adds carbon monoxide detection at the same price.

Frequently asked questions

Which Lightspeed headset is best for student pilots?

The Sierra is the most affordable full ANR headset in the line at $749. Students who expect to keep flying after the checkride usually save in the long run with the Zulu 3, thanks to its 7-year warranty and more durable build.

Is the Delta Zulu worth $200 more than the Zulu 4?

It is if you want carbon monoxide detection or a hearing profile tuned to your ears. If your priority is keeping an iPad and a phone connected over Bluetooth at the same time, the Zulu 4 is the better fit.

Is the Zulu 4 better than the Bose A30?

The Zulu 4 costs $200 less, adds dual-device Bluetooth and carries a 7-year warranty versus 5 years on the A30. The A30 is slightly lighter and offers three noise-cancelling modes. Comfort is personal, so we recommend trying both on when you can.
