Peter, I also suffer from the same type of hearing problem and can 
sympathize with you. At times CW just isn't fun anymore, the ear ringing 
is about the same pitch and tone as the CW. I selected the 500Hz filter 
as the 250 was just too narrow and actually was a detriment to copy. I 
bought a MFJ 616 and the difference in copy was amazing. Say what you 
want about MFJ, but this item just works. Once adjusted it makes copy 
for CW much easier and much less tiring. HTH.....73
