Bought 2, one worked

I bought these a year ago, one worked very well, and one buzzed. But I had no trouble charging them and they were a good solution for an overseas flight, except for the one that buzzed. I used the good one again on a car ride to let my grandson watch movies on a car ride. My husband and I could listen to the radio and visit with each other without him noticing. Today I pulled them out to charge for my daughter to use on a plane. Neither one will charge, no light and the noise canceling is gone, if I switch on the noise canceling no sound comes through. These are a great idea, but they do not last and really, only one worked for noise canceling at the beginning. I bought them in May of last year, it is April now, not even a year of use. I had them stored carefully in their bags.
