When it comes to other features, both models are very much alike. Both the Zulu 3 and Sierra are active noise reduction (ANR) headsets, that offer superior noise reduction, Bluetooth, audio input, audio priority to mute music when receiving or sending radio transmissions and more.

Both headsets utilize standard AA-type batteries, making it easy to quickly change batteries before or during a flight when they run low. Both can last for about 40 hours of continuous use.

The Lightspeed Zulu 3 can be considered a more premium version of the Sierra. It has all the same features, with some additional advantages such as an extended warranty, a lower weight (14.6 vs 16 ounces), auto shut-off, more available plug types, and kevlar reinforced cables.

For the cost of these headsets, you expect the best. They both do an amazing job delivering just that.
