Summary: Compared to the siblings:
This is the Promedia version of Klipsch Image S4 (and their S4i iPhone counterpart). Besides the gamer-friendly red and black coloring they also differ from the S4i by having a single button mic rather than the 3-button Apple remote. They also come with a Y-adapter that splits the TRRS plug into separate plugs for PC headphone and mic connectors.
Pros: Good fit with nice quality stock tips, fairly compact, soft cables seem to do a decent job with microphonics
Cons: Bass-heavy, a bit lacking in the upper ranges, soft cables don't feel very snag resistant.
Summary: these are great sounding earbuds, they feel comfortable and look pretty good. the one huge problem with these are that every time the cable touches your cloths you get this thudding sound go straight into your ears, very disappointing .
Summary: Coming from a Sony MDR-V6 for my main set CAN, I'm very use to a flatter frequency response and far less bass. The large amount of bass can overpower the main track in some my electronic tracks however it is just strong enough in most of music making it far more enjoyable. This was mainly observable on my desktop PC with a Creative X-Fi, but on my Samsung Galaxy S, the extra bass was just enough to push the weak default source to a far more enjoyable level.
Pros: Build Quality, Built in Mic, Y-Adapter for PC
Cons: Stock tips are too soft, could not get a good seal;
