Query: Sound but no comfort

Shares excellent drivers with KSC35, KSC75, Portapro and Sportapro models. That is good--very rich sound with the perfect amount of bass emphasis.However, as others have mentioned, the band is way too narrow--almost like it's made for children. I doubt any male head will fit into these things without the band digging into the sides of your scalp! Like the previous reviewer, I made the mistake of trying to bend the band to widen it--snap! And these were brand new!!! Luckily, the lifetime Koss warranty came through to replace it for only $6 s/h. Because the headphones are brutally unforgiving for my head, they are still in the package unworn. I highly recommend the behind the head band style of the Sportapros if you like this style (I DO--I can wear a cap without band interference) and feel it is more easy and comfortable to wear than the clip-on ear style of the KSC75/35.
