Pros: sound surrounds you, enough bass to make you want to sway
Cons: oval ear pieces
Used them for a year or so. Very happy. bass is tight, not booming, highs are pleasant.
They are a bit slippery to fiddle with for me.
The material the ear pieces are make my ears itch after about 30-40 minutes. I had to have Klipsch send me the other size that is not included as none of the included ones were fitting properly. Even then, out of all of them, they don't fit as I would like them to. The pointed ear pieces are all way too small, the oval ones I ended up NOT aligning as suggested to get them to fit the best for me.
The cable is thin and tangles easily, as I'm sure others do. I have been fairly gentle with them so I cannot attest durability. Though, I do run 20 miles/week with them and no moisture or sweat issues.
I would only get different ones if I could find the perfect fitting ones, otherwise I am quite happy.
