Pros: Good sound quality, decent bass, great noise isolation when they're in right.
Cons: Do not stay in while doing anything other than sitting! Most of the quality and noise isolation comes from the fact that they are bent inward and get rightttt up again...
Summary: Before these, I had the Etymotic ER6's and the Ultimate Ears TripleFi. I'll be comparing the Klipschs to these. First off, let me explain quickly why I bought these.
Pros: Very comfortable and secure, great isolation
Pros: Comfortable ear-buds, good noise-cancellation. Sound was average for products I've tried in this price range, however I am almost satisfied that I won't find ear-buds ...
Cons: I don't listen to Techno or other heavy bass music, but these do lack the bass compared to other ear-buds I've owned, so naturally I was a bit disappointed. Good sound...
Summary: I bought the S3 after reading reviews online. i must say, it wasn't what I had expected. I use fairly high end equipment at home for msuic, so am accustomed to good sound...
Summary: good high end but lacking elsewhere. can get rounded sound by turning up to almost uncomfortable level but for outdoor use not balanced enough.
