"I love my HS-1! Great headset for the money. Very comfortable, good value for the new pilot or the seasoned one."

—Scott Gribble, Gig Harbor, WA

"This is one of the toughest headsets around. In March 1997, the home my flight instructor, another flying student and I were living in was struck by a tornado. Luckily, none of us were home at the time. My ASA headset was later found on the ground a couple of blocks away—in the rain and missing an ear seal! In the meantime, I had already purchased a Telex 5000E headset to replace my ASA HS-1. But after replacing the HS-1's ear seals with gels, I found them more comfortable and better sounding than the Telex AND the David Clark I had recently borrowed. It's been 10 years since I went to the FBO and bought the cheapest headset I could find (my ASA HS-1). I never expected I'd still be using them today. I may never need another headset."

(...Especially with the lifetime warranty.—Ed.)

I needed a headset (after breaking my friends very expensive headset) for a ferry flight and came across these at Boeing Field. I used them for my flight from there through the Aleutian Islands and onto Japan. I found them very comfortable for the entire journey, including the ten and twelve hour legs. My friend thought I might find them heavy but I did not notice that at all. They sealed around my ears easily and I appreciated being able to adjust the volume with the knobs on the ear cups, so we both could have volumes we were comfortable with during the flight.

All-in-all I was/am pleasantly pleased with my purchase.
