The Bose A20 has improved sound quality rather than the Zulu 3. It features acclaimed noise reduction, but the A20 has 30% greater noise reduction plus has built with active equalization for clear audio. This one is 30% less clamping force compared to the Zulu 3. 

Furthermore, the Bose A20 delivers customizable audio prioritization control. So far, it allows you to mute an audio signal when you receive communication. 

Lightspeed Zulu 3, by contrast, has great sound quality as well but not much like the A20. However, you can enjoy excellent call clarity from both headsets. 

Battery Life 

Speaking about the battery life, the Bose A20 might last longer than you think. It mentions, the device provides 45+ hours with its two lithium-ion batteries per charge. But you can use the headset for 50 hours straight, which is better than other aviation headsets. 

The Zulu 3, on the flip side, delivers up to 40 hours of battery life per charge. This cannot provide you a fantastic battery lifespan like the other one. That’s why we recommend you go with the Bose A20. 

However, both headsets feature auto-shuts off, which saves battery life by turning off the headset when you are not using it. 


The Bose A20 is the clear winner in terms of comfort because this one is the lightest headset. It is only12 ounces, while the Zulu 3 is 48 ounces that are slightly heavier than this one, plus not ideal for wearing for a long time. 

These two are built with a taller head pad to ensure maximum comfort and performance, even for the smaller head shapes. Anyhow, the size of the Zulu 3 is 13 x 11 x 5 inches, while the A20 is 8.43 x 6.34 x 3.15 inches. Hence you can see the A20 is also sleeker than the Zulu 3.

But the Zulu 3 does not have a swap feature. You can connect the mic to the right or left earcup, whichever you want to communicate convenience or personal preference. 


Both headsets come with two AA batteries, plus an attractive carrying case and a control module for volume control. While the Zulu 3 comes with a foam windscreen, cord clips, and patch cords.
