Thanks to all who replied to my inquiry! My first choice was going to be the Heil until I saw that some of them had problems. When I was on the BHI website, I did see the that noise cancelling module, but prefer to listen sans headphones. I could never get used to them again after those 1970's UMASS years when one night my trusted and true Koss headphones managed to wrap themselves around my neck. I had been drinking kinda heavy that evening, and the cord left an imprint on my neck that didn't go away for awhile. True! So it would seem that the way to go might be the BHI DSPKR used on the lower settings until I can get the things I need for a folded dipole.
I attended my first concert in the summer of 1970 (The Grassroots!), and that started a long run of maybe 40-50 concerts, mostly during the 70's, but a fair amount in the 90's, with the last one in the early millenium, which fulfilled a lifelong wish to see the Who! I think the loudest was probably Black Sabbath in 1971 in Hartford. That was back in the days when they were still hungry and Ozzy had yet to become a parody of himself. My ears were ringing for a couple days after that one! So I have done quite a job on my hearing over the years....back in the 80's I would spend hours at a time straining through the hets and the noise with the FRG-7....I don't think that helped much either....and then there was the old Pioneer SX-525 with the Advent speakers...not to mention my late brother's 90's grunge band cranking out in the garage.....sooooo, I need a little boost in the speech range of frequencies. The music is no problem, as I have a fairly good database of memories:not to mention the use of Shazam which I use on a regular basis. Again, thanks for the input!
