Ive been using the new headset during my taildragger training. It works well keeping the noise down to a minimum with the windows open during the summer months.

Just open your wallet and do it. They are worth it.

Totally amazed with the Sierra headset. Extremely comfortable, Love the stereo sound through blue tooth or hard wire cord. Clear phone calls. The only draw back I am used to hearing my engine for change of sounds during different phases of flight or when leaning, I now have to really on feel. Great value for the price.

Good noise cancellation even with the ANR turned off, excellent with it in. These are also very comfortable.

Decent value. if you are not wearing a headset 8 hours a day you should look at this headset. As a general aviation pilot with 4 hour IFR missions couple of times a month I found this as a good deal especially with a $250 rebate from aircraft spruce on a old DC headset trade in.

Very good headset. Sound is very clear and the ANR makes all the difference from a regular headset. Great service from Aircraft Spruce Canada. Shipping was very fast.

I gave it a 5 because of the value compared to more expensive sets out there. They are just a little bulky looking (only reason I almost rated them a 4) but neither the wife or I notice it wearing them and we wear them all day sometimes! IMO theyre superior to the David Clarks that are a few hundred dollars more. Ear cups very comfortable and soft. Isnt painful putting them on when its 30 degrees:=)) Battery life seems to better than advertised!

I have used the Sierra for a couple years now and like it very much. It is light and very comfortable. Bluetooth works great.

The mic arm connection at the ear phone are not very tight so the mic arm continually falls down so the mic will not stay up at your mouth when you need to speak into it. I have this same problem on both sets I just bought.
