Pros: Extremely comfortable - I absolutely love how they fit. The only earbuds I've ever owned that I could wear all day without any irritation to my ears. Also, they did have good bass response.

Cons: Right out of the box, I thought the audio quality is middle of the road, if not a bit on the low end. Bass was good, but the mids and highs were muddy and scratchy. However, I bought them to listen to audiobooks and podcasts, so I wasn't too concerned. I used them daily for about five weeks when the wire was starting to short out at the base, just above the 3.5mm plug. The audio would cut out with the slightest movement. Pinching it, or tugging to left and right could sometimes restore the sound, but it quickly got to the point where it was almost impossible to get any sound out of 'em. I recognize that reliable earbuds are a myth, and that they ALL short out eventually. No matter how much you spend, they just seem to be a disposable product. However, five weeks in inexcusable. I expect to get a year or two at this price point, especially from such a reputable company. So, I called Klipsh to activate the 2 year warranty. The guy at the call center gave me instructions to email promedia@klipsch.com and explain the issue and attach a copy of the purchase receipt. I did that over a week ago, and haven't heard a peep from Klipsh. Just emailed them again, but I don't have a lot of hope that they're going to respond at this point.

Overall Review: Once I heard the short, I started shopping again. The Panasonic RP-HJE120-K have a similar design and audio quality at a HUGE discount compared to these. They're not nearly as comfortable, but if I'm going to be forced to buy headphones every 5 weeks, I'd rather pay $7 instead of $40.
