Briefly I gave it 1 star because the product did not work as it should. At least the manufacturer should indicate "Not for helicopters" Details: I am a professional helicopter pilot and the A20 is part of my life. I have two now, one built into my helmet, and one for free wear. I read all the reviews before buying and honestly did not really believe in the negative ones. As soon as I got the A30, I jumped into the helicopter for 7 hours of work. The first impressions were very positive; I liked the non-slip plastic on the new battery compartment, the thin cable, and less pressure on the ears. Noise cancellation worked well. The first negative impression came after the first radio conversations. The sound of the ATC seemed very "dry", unnatural. I would say that the sound frequency range is shifted to the top (high frequencies prevail). In reality, I think this is the peculiarity of the digital processor. The worst thing happened later. At some point, the right earphone started making a Bang-bang-bang sound. It was very loud. Not only couldn't I hear the ATС, but it also was hitting my eardrum hard. It looks like the digital noise cancellation picked up some vibration or sound or both and started autoresonance. I tried for 20 minutes to fix it; I tried moving the headphones on my head, pressing them harder, but nothing helped. Eventually, I had to turn off the noise cancellation and continue the flight without it. It's good that there was no tense radio communication when this happened. Imagine that you went deaf because of a Bang-bang-bang somewhere in B airspace or were working in close proximity to other aerocrafts. It’s really not safe.

Background: I fly helis with doors on and doors off operations. Have 90% of my flight time on Bose A20s and what I'm basing this review on. I've also received feedback from a Helicopter Network Facebook page to see if it might have just been my headset and to get others opinions on them, and they all have had the same experience. For $1,300 you expect quality, not them throwing a product out and trying to cut their costs by using cheaper materials and still expecting you to pay the same price. I will be returning them, and sticking with my A20s. Pros: The design and the look is nicer. The headband cushion is more comfortable. Cons: Feels cheap and not durable. (Headset and the controller on the cable is cheap plastic. The switches on the controller have so much play in them. The cable is also really thin and unrealistically long) The noise canceling is hot garbage. (I hear so much wind noise and the bad feedback. Almost like a "thump thump thump". It's almost like bose didn't do testing in doors off operations for helis.) The sound coming through the headset was terrible compared to the A20. It sounds like an old radio and not crystal clear like the A20s. The case is a step down from the A20s case. (No outer pocket, no licenses holder, and no extra battery holder. Although, i will say the material is nicer quality)

I’m training in helicopters and I found it really disgusting having to put something like a headset that I don’t know how many people just sweated into and having a boom that close to their mouth. I figured id be flying for a while and my instructor recommended the Bose a20’s. I went with the a30’s. BIG MISTAKE. That “Thump thump thump or thud thud thud” that another reviewer mentioned? Same thing. I nearly blew my ear drums out. Plus they just didn’t work. When I got home i played around with them and found out as well the wire that comes from the bottom of controller to headset was messed up. If i held it to the left I could hear my music and once I let it go NOTHING. Returned.

Excelent

The A20 beats these in every category. They A30 feels cheap the wire is significantly thinner and cheaper feeling, sound quality well I don’t know I sent them back immediately after I open the box an ordered A20’s I would do it! YOUVE BEEN WARNED
