Pros: These are by far the best ear buds I have ever owned.. and I've owned many. The sound is crisp, clean, and zero distortion at any volume. Surprising amount of bass (which I like), but not overpowering. Highs and mids are clean & clear; as you'd expect from Klipsch. They're simply amazing. I'm so glad I was able to get a set! Wish I'd picked up another set for backup.

Cons: They're very difficult to find now!

Overall Review: Highly recommended!!
