Coming from a former college athlete, I was skeptical about a croc tennis shoe. This cheapness keeps me from losing it when my earphones "disappear" several times a week. I expect to get at least a year out of a pair of shoes and these are terrible for durability. Ive even got a spare, in case a similar issue crops up in the future with another piece of equipment: Cheap for the aggravation it solved. Great fit into my oakley batwolfs. Absolutely worth every penny, and for any gym rat, it should be the belt of choice. I was expecting them to made better and very comfortable considering. Overall the Sony app is ok; it allows for some sound mix customization and has more features than the Jaybird earbud app, but thats a low bar (the Jaybird app is truly bad). No idea what they were but they made a mess. Claw grip may work, but fingertip grip like I use is a perfect match.
