Query: Work fine, but don't last

Good traits.- They do take getting used to, but if they are free around your neck they stay in fine.-Sound quality is fine for running headphones-If you need to hear your surroundings, you can always invert them and they hand above your ears.Bad traits.They DO NOT last. I had one pair for about 6 months and one of the buds just went dead after it faded in and out for a week. I liked the functionality so I got another pair, and it also lasted about 6 months until they had the same problem. The left bud just dies, happened to both pair, seems to be a fault of the product that the same thing happens twice. Not good enough life for the price. I'll be trying something different.
