"I have been using my Sennheiser HMEC 25-KA in the Cessna Conquest flying mapping/survey for five to six hours at a time. So it sure is nice to have a light weight headset that I forget is on. I am very pleased with the quality of the set and the sound."
Geoffrey Olsen, North West Group 

"I have been in the B727 for almost five years and just started using the HMEC 25-KAS. What a fantastic improvement. The noise level is almost nonexistent. I'm able to turn down the volume on the radios, at the same time hearing both the controllers and other crew members more clearly. The stereo version also allows me to separately set the volume level in each ear. I definitely recommend it!"
