Summary: They just don't last that long. I think this pair only lasted about 5 months after purchase. I've gone through two of these and the same problem occurs: The left/right earphones die after a few months of use.
Pros: They fit well, the sound is decent and they get the job done.
Cons: Has a poor design for the audio jack. It becomes staticy within a few weeks as a result. The headphones' left/right channel dies within a few months.
Summary: I used to own behind the neck type headphones for jogging on the treadmill and working out, which were great until the right headphone stopped working..maybe from sweat getting inside it. I thought these would be less bulky and thus more amenable to working out, but never got to try them!
Pros: Sound quality seemed good but I never wore them for an extended period. Just took them out of the packaging and realized within a minute that they were not made for my ears.
Cons: Non-adjustable and made for an ear size much greater than my own. With the buds in the ear canal the ear clip was way above the crease where it should have rested.
Pros: Good sound, stay in your ear pretty well, not terribly ugly
Cons: There's a clip thing attached to the cable that is supposed to let you connect it to your clothing, or somewhere so it won't bounce around when you're running, or get in the way when you're doing something. However, the way the clip itself attaches to the wire leaves something to be desired, sinc...
Summary: This type of earclip is the only way to go for me. earbuds that come with mp3 players are hard to get a comfortable /secure fit. even when they dont fall out they FEEL like they are going to, which is so distracting.
Pros: Price, comfortable, decent sound quality, wont fall out of your ears.
Pros: They seem to have pretty good sound quality and bass response for little earbuds. I doubt they're the best but they're excellent compared to the ones that came with my MP3 player. I got them because of the ear clips, which certainly do help a lot.
Cons: Personally, however, I have somewhat small ears, which means that I need to constantly readjust them, despite the ear clips. Still, they don't "fall off" nearly as easily as traditional earbuds. If you're into hardcore mountainbiking then that might be somewhat of an issue. For walking or casual ...
