I've been shopping for a plane. One model for sale, I asked for logs, was checking out what I could find out about the owner online. What I found out was that the guy was likely an audiologist. When talking about the plane, I asked about A20 vs the Bose model that goes in ear, is lighter weight, might give me more head room. He stated he would never fly without the ANR and that he flies with A20.
Why after some hearing loss is your budget limited? Is it not the kind of thing where hearing protection is priceless and the best product available is worth the price? This is coming from someone that uses lots of loud equipment that had a few months of tinnitus thinking I was going cray cray. Testing showed 4k hearing notch loss.
