I've owned many in-ear earphones, from Sony MDR-EX71SLB to Shure E2C-N via Creative EP-830 - and some Sennheiser, briefly, not to mention some modest Samsung earphones (go figure, the best and most durable ones I've had). The latest ones were SoundMAGIC E10, which were in the OK+ category.
Immediately these Skullcandy Titan feel very comfortable in the ear and the sound is wow! Clear crisp sound in the full spectrum, with powerful yet not overpowering bass. Added bonus they have a mic, which I needed, and which doubles up as a control (pause/mute, next/previous song). They isolate noise better than any other I've owned in the past, and I don't think they themselves leak too much sound (a barely audible tchk-tchk at medium volume in a quiet room).
All this for a lot cheaper than any of my previous earphones!? Where's the catch? Well, I'm in no rush to find out. The earphones look reasonably sturdy and well-made, with a cool logo to boot. I have no illusion though, I've stopped regarding earphones as eternal things, they're just commodity - when they last me a year or so, I consider they have rendered me an honorable service. So when I find such good ones at twelve quid-ish, I'm tempted to stock half a dozen, and hope it will do me for the best part of this decade.
