I think that there was a QST article some years ago regarding an audio filter/equaliser tailored to match one's hearing loss profile. The author claimed that it enabled him to hear his radio much more clearly.

My hearing is largely deficient in the higher frequencies due to army weapons training in my youth and no doubt exacerbated by subsequent industrial noise. This is likely to be a problem that affects a good proportion of list members. Loss of the higher frequencies means that we miss the word endings which convey a high proportion of the intelligence we are trying to receive. Maybe, just maybe, the want of 'good' audio on K3s is due to a wish to be able to hear more clearly? Maybe the article in QST to which I am referring would be a good way to go.

I will see if I can find it and post the details to the list.

I purchased a set of Radio Shack headphones a few years ago that had separate level controls for each ear. They were reasonably priced, very comfortable, and sounded great.

You might want to have a look at what they are offering today. Their web site shows a pair by Coby for only $11.00 that has independent controls R/S Cat Num 55010925. They also have another set that looks a bit better quality, and has a volume control, but I can't tell if each side is independently adjustable, for $13.00 . Their Cat Num 55010865. The usual disclaimers apply.

balance control which puts more AF juice into one

side of the headphones compared to the other.
