Summary: I was so excited when these arrived yesterday. Tried them out this morning and immediately repackaged them for return. Not only was it nearly impossible to get the earbuds into the ear hoops, but even worse, these have absolutely no bass. I couldn't even believe how terrible these sounded. I wanted it to be some kind of fluke so I tried them with different devices and songs but still no...NO BASE. This is simply no acceptable to me.
Summary: They are well constructed for athletic use, in particular, the wire at the end to the plug was what failed and is how my set broke. They were great when the worked. For $50, I would expect them to last longer than 5 months.
Pros: The headphones sound great and mic works well. No complaints from folks when I use them for phone calls.
Cons: The right earphone stopped working after using the set for 5 months.
Summary: I love using my iphone for my music when I run, because my husband is gone a lot and don't like missing calls from him, but all the previous headphones i purchased wouldn't hold up to my sweatie runs. So after many many purchases I have finally found a ear phone that sounds great and i can actually talk on it while running.
Cons: For the cost i would expect better engineering on the physical durability. The wires going into the jack are poorly secured. headphones that are for athletes should be expected to be abused by the cord however the wires easily pull out and disconnected from the jack.
