Product Review; "Unfortunately this model was discontinued a few years ago, and they are becoming increasingly more difficult to find every day. If you are lucky enough to find one for sale, they produce a fantastic sound quality, with well balanced bass and highs. The input jack is a 1/4 plug, so I use a converter to standard 3.5mm. It's sad good American made headphones like this are so scarce, but I choose to seek them out, and I haven't had to buy foreign-manufactured headphones in years!" -MadeInUSAReview
