Breaking development, I picked up a pair of the Portapros locally. This is what can happen when I start reading up on a product and get on youtube, listening to reviews, start price checking online and then look for them in some random store that just-so-happens to carry headphones!
Anyway, I won't see the massdrop Koss PP until at least the 3rd week of May, who can wait that long? They really are great headphones, btw. They pull off the trick of being warm sounding but still giving good detail. I immediately liked them better than some Bose phones that were originally about $150, and my Nad HP50. They're so easy to wear, very light on the head. Definitely going to be my goto for jogging.
That reminds me I spent almost 200 on a pair of Bose in ear headphones several years ago, and found them lacking when comparing to my other headphones. These Koss also stomp all over them. I've been looking at mods, I'll have to try some of those pads, virak.
