Pros: LIGHTWEIGHT, INEXPENSIVE, GREAT BANG FOR THE BUCK
Cons: NOTHING FOR THE PRICE
I bought my first pair of these when they first came out in about 1986 or so and have been using them for portable audio ever since. first with Aiwa Walkman tape players and now iPod Classic 160. I have gone through a number of them since then, but the great thing about Koss, no matter what you may think of their cans today, is their lifetime warranty. If the cable shorts out, or they otherwise break, or become unusable, just send them back to Koss with a check for $7.00 and they will fix (maybe replace). Used to be $5.00. Check with them for the current repair rate. I've bought a few more pair, had several repaired by Koss, and been using ever since for portable audio. Great value, great sound for the bucks. I've just bought some B&W P5s, so maybe I will have something better to wear outside, maybe not. Who knows. A definite bargain. Currently about $35 on Amazon.
