Pilot Stories

This headset offers a lot of bang for the buck — great comfort and noise canceling for under $700.
   — Bret Koebbe, Senior Flight Instructor
I don't have a single complaint about this headset. It's light weight and comfortable. It breathes! After a 2 hour flight in Phoenix, AZ during the summer, my head isn't soaking wet.
   — Phonecian, Pilot
Great headset from Lightspeed. I purchased one once I seriously got into my training and haven't regretted it. Earpieces are comfortable, and the ANR works great. I'm told the Zulu is marginally better, but bang for your buck this is one good piece of equipment you won't regret owning.
   — Metroid "jkb11", Pilot
This headset is awesome. Its affordable compared to all the other headsets with the same features and works great. I'm proud to wear this headset and I no longer hurt on those long flights! Oh, and I can hear ATC clearly!
   — EROK, Pilot
The noise cancelling feature works extremely well. I can still here the engine and prop of the airplane, but it is not as loud as with other headphones I've used. These headphones are light and comfortable. I have tried using my MP3 player with these headphones and this feature works well. I have yet to use the Bluetooth feature. Good product and reasonable price.
   — baddtaz, Pilot
The Lightspeed Sierra headsets are light and very comfortable. Great ANR. The Bluetooth option for my phone and the iPod connections are great additions. I love the reduction in sound from my iPod when there is any incoming communication.
   — mlaprise, Pilot
Great ANR, works great, clamps on the ears nicely and securely, mic-movement for left and right ear is great. Very satisfied. I didn't want to spend money on a cheap non ANR headset, I did a lot of research and decided to go with the Sierra. I think it's worth every penny and more. Like I said this is my first headset ever, but I am extremely pleased with it. My flight instructor likes it so much more than his Lightspeed Thirty3G headset, he ordered a Sierra for himself.
