Pros: Comes with a nice case
Cons: Sound quality, build quality and too noisy for walking.
I bought these to replace my dead Klipsch Image S2-ii after reading many reviews, because I wanted to try something else in the 60-70$ price range for use with my Sansa Clip Zip, and was very disappointed. Even with the proper ear tips (small), they sounded lifeless and dull in terms of bass, lows, mids and highs compared to my former S4-ii, which I know are a bit too bassy. I use AKG K712's with my Sound Blaster Z, but still did not find the Klipsch to be a significant downgrade by comparison, while the DTX's sounded awful, in fact I barely preferred them over the included in-ear phones which came with the Sansa Clip Zip. Furthermore, minor tension while making cause a significant amount of audible noise, as do minor movement compared to the S4-ii's. The Beyers were happily returned in favor of the Audeo Phonak PFE 122's which sound far better, even though the Sansa Clip Zip is not good enough to power them (they sound amazing when connected to my SBZ though).
