I purchased this headphone cable for office use. I treated it well and never put any sort of abnormal stress on it nor was it ever in an abusive or physically active environment. The cable was never once crammed in a pocket/backpack or kinked in any way. After only 4 months, they're already cutting out. It's got a nice outer sleeve on it, but the wires inside are apparently thin with poor connections. I've had $10 marshmallow earbuds last longer than this cable and I was wearing them to mow, work in a physically demanding job, etc. Would not buy again.
