Pros: They worked great for the time that I had them. When I first got them (from the free rebate!), I was unsure of their performance. They looked pretty cool, and when I put them in, they fit with an AMAZING seal. I like the L jack on the headphones. The ability to wash them was really great, too. They became my lawnmowing headphones, mainly because if I grab the cable by accident, they did not come out. Yes they needed to be reseated in the ear, but at least they did not...
Cons: The problem with the seal is that they can't be reversed, as in the right headphone does not fit very well, if at all, in the left ear. But who does that? So not a big problem. The other problem is that the seal was so powerful that sometimes it hurt. Yes i am serious. The other problem is that the L angle on the connector was too thick on the outside, and did not sit well in my Casio Commando, which has an audio jack that sits a little inside the device.
Pros: I don't know what everyone else was listening to, but I really love these headphones. Nice clear Highs, and full Bass when I listen to my music. Fit nicely in me ear and come with different sizes if you need something smaller. They are just $18 headphones so I don't expect miracles, but they reproduce sound nicely. Most of my music is in FLAC so it sounds amazing to me.
Pros: Strong cables, good rubber, and a very comfortable fit make them ideal for running. They also can be comfortably looped over the ears to get them to stay on while running, and I haven't noticed any problems from sweat.
Cons: The sound quality is bearable, but not much better. Music sounds pretty bad, and voice from audiobooks or lectures is scratchy and hard to understand, especially if the recording quality was only marginal to begin with.
