I purchased these just for light use, mowing the lawn, etc. Only wore them maybe 20 times over the course of 8 months. Stored them carefully. Absolutely never abused them or pulled at the cords. One of the ear buds now does not work at all. I contacted Peltor - they said, sorry you're having the difficulty, but the warranty is only 90 days. Would not buy again. Good concept - but not durable.
