Appearance: As you can see, these earbuds look beautiful! The silver chrome and glossy black give the IEMs a sleek and stylish look, though this comes with the side effect of being fingerprint magnets. These buds are pretty well built, and have stood up to the test of normal use/abuse that comes with daily usage during my morning and evening commutes. The drivers still work perfectly, and with the exception of a few micro scratches still look like they did when I first bought them. These are definitely a stylish pair of headphones that stand up to normal usage well.
Sound: The most important aspect in judging a headphone is its sound. And certainly the Klipsch Image S4 hold their own pretty well. I'm a fan of rock and metal, thus I tend to prefer a more V-shaped sound, with emphasis on the mid-bass and treble; these Klipsch's fit the bill quite nicely. Emphasis is definitely placed on the bass, with a powerful and boomy mid-bass, that unfortunately slightly bleeds into the midrange. Subwoofers these are not, but they definitely have a strong boomy sound, and when first used caused nausea. This subsided with repeated use as my ears became accustomed to their sound, and now I'm loving every minute of them. The midrange is definitely its weak point though, with vocals feeling less intimate than other high end headphones, sounding more receded. The treble however, is beautiful, with guitars shining above the pounding bass.
No, these aren't the best sounding headphones/earbuds/in-ear monitors ever, but for the price they're amazing. The isolation is superb too, thanks to their custom oval tips, being THE best I have ever experienced. And with a 2 year warranty these guys will keep me busy for a while.
Verdict: Worth the price of admission, especially if you can get them on sale.
Final Grade: 8.5/10
