Query: Fell apart. Clog with sweat when running. DON'T BUY

First Amazon product review. Don't buy these. They have basically fallen apart after only two months. Both little headphone / speakers have fallen out of their places and now only kept on by the small speaker wire (and scotch tape). They also clogged with sweat after a hard running session. And so the quest continues for a pair of headphones that actually work while running (and don't fall apart)!
