Best Sport Headphones
Posted by arvivaz from Los Angeles, CA on 2014-03-10

Recommend Product: Yes
Pros: Very Comfortable, Very Good Sound
Cons: Control Buttons A Little Hard To Use

Wear it and forget about it. I ride my bikes with it, go to work with it, use my iOS devices with it. These are the most comfortable in-ears I've ever used, the behind-the-ear retention is never uncomfortable. Sound is on par or better for buds; it just needs to be inserted into the ear canal properly. On the down side, the multiple function in-line control buttons are a little hard to use, kinda small. Another nit is the cable, which has a removable retention clip, but cables being cables, sometimes its annoying to untangle. Works well with iphone, one click to answer, incoming audio is excellent and I can be heard well enough on the other side, even while pumping steady on my SuperSix. It's out of the way of helmet straps and lenses, so that's a plus too. SQ=4; C=5; L&F=5; D=5; Useability=4.
