Works well, very durable
Pros: Love them Cons: They are a little bulky
So far, awesome!
I have been using the loaner DC headset during training and decided to get my own. The difference is amazing. It is so much easier to hear everything, and even the quieter and more distant radio chatter is much easier to hear and more importantly understand (no more did he say he was nearby? scenarios). They are very comfortable so far and no complaints at all. I was looking for the best bang for the buck with ANR and am happy I chose the Sierras.
I already use a LS Zulu and bought the LS Sierra for the passenger in my Cessna 150M, to replace an older passive Pilot headset. Works great and passengers appreciate the ANR and ability to listen to music from their iPod or smartphone.
My two old Lightspeed headsets were no longer repairable . . . but they allowed me their best trade-in anyway and sent me a pair of the best noise-cancelling headsets I've ever used.
