Review title: Blade heads only
Product review: From a sound standpoint, they are acceptable, with some hiss in an office environment with lots of computer equipment around. The range is decent, but you get some signal loss if you turn in certain directions. My biggest gripe is that the headset is uncomfortable to the point of being unusable. It is very tight, and the cups tend to ride on the ear, not around them, so after 30 minutes or so, you have to take a break. Overall, I am not pleased. Koss offered to exchange them for another set of earphones of equal or greater value and they would give me $90 toward the purchase. So I have a bad set of $125 headphones and I can upgrade to something better for an additional $90 or more. Maybe not.
