5 and 9. My previous Bose ie2 earbuds lasted 3 years under everyday use and fairly frequent abuse, like wearing them while sweating in the full sun mowing the lawn (under hearing protection) and weedwacking. I dont recall these saying they were noise cancelling, but I had the tv on relatively loud and couldnt hear it at all. JBL if youre listening i am not happy customer. Last week I also gave a Tile to a friend who is always losing her keys, and she has used it several times already. Great custom fit around the gas tank, exhaust, etc. I made my first trek in the Cobians and I stuck with them. While this case does have some rubber or silicone pads within it, the Pros charging case rattles around within it. They offer great support and no blisters like hard dress shoes. Todavía me sirve dos años después.
