Summary: The sound is excellent with an iPhone, the buttons are easy to use. Its a little cumbersome to put it on, but once you get the hang of it, you should be able to get it on and off pretty easily. Excellent value for the money. Doesn't fall off your ears and doesn't need any kind of adjustment. I haven't compared the sound quality to any other products, so audiophiles may think other wise.
Pros: Stays in your ears and very comfortable. Sound quality is good enough for me( I am not an audiophile) Cable length is adequate enough to route this through your shirt.
Cons: Difficult to put on the first couple of times.
Summary: I had difficulty using the Apple ear buds, was looking for something that worked. First use was on several flights last week. Didn't need volume as high as with the old buds and due to the soft earpieces, I was able to hear mid flight announcements and the stewardess just fine without removing the earpiece. For those of us who can't afford/validate the Dr. Dre sets, these are a very good consolation prize.
Pros: The carry case is large enough that I can fit my music player inside. love the multiple cord and ear piece options. Appear more durable than other sets.
Cons: Due to all of the cord and earpiece options, set up the most advantageous one so that every time you open the pouch half a dozen parts don't fall out.
Summary: Overall these seem like good headphones for athletic purposes but the true test will be durability. I purchased these as an alternative to PowerBeats. I much preferred the Beats sound and fit over the Polk's but after 3 pairs of Beats failed because of sweat, I decided on trying these out. These serve the purpose, with acceptable sound quality, for exercise but I think I'll get a better headphone for travel and home use.
Summary: These phones fit great and have never come off, or even loose, while hiking or running. The volume control is easy to use and works while my iPod is locked. The only downside is that they can't handle much bass at max, or near max, volume.. This is fine for normal use but a downside when mowing the lawn or doing another activity with loud background noise. Overall, I'm happy with the purchase/value.
Summary: Nice phones. They don't sound quite as good as my large Sennheiser cans (obviously) and lag a bit behind my Sennheiser on-ear portables. However, I needed something that would allow me to answer the phone while running/biking. These fit the bill, and the fit is very secure. No worries at all about them staying in during strenuous exercise. While the mic ends up being rather low when all hooked up, it is easy to clip it to my riding jersey to put it in a nice position.
Pros: fit, not "great/awesome" but definitely good sound quality. Good fit once you figure it out - phones NEVER fall out of your ears
Cons: Mic ends up a good distance from your mouth when all hooked up. Only an issue while biking, and the provided clip takes care of this. Can take a bit of wrangling before finding the best fit.
