There are others that have spot on reviews here, but I wanted my voice and review to be heard and added. I intend to keep my review short and simple, since we are after all talking about headphones.
First off, these are great sounding headphones. To echo what someone else said they don't have the overbloated bass found often in other headphones. Although, on the flip side, I would almost like a little more bass. But overall, less is more in this case. What does remain though is a nice, clean, and liquidy sound. Liquidy is a hard thing to find in a pair of headphones in this price range I feel.
So whats it's one problem? While I absolutely LOVE the look and design of these headphones (including the bungie cord texture and the magnetic earbud connection) it is the one thing that causes it's flaw. And that flaw is that because of it's rough texture, if it rubs up against something you hear it transfer to the earbuds, and thus interferes with the sound. While it is noticable to tell that sound from the music, it does distract after a while.
For instance, I used it while shoveling snow (that time of year)...I could hear everytime I moved. I imagine running or exercising in any way would be the same case. Now sitting still. No problem. Overall this one element brought the overall score down one star. Still an awesome and eyecatching set of earbud headphones, but not perfect.
