Absolutely the worst quality products in the market. They certainly don't believe in their brand. I bought two QC Earbuds and both stopped working. Tried all the troubleshooting with no success. I contacted customer service and their solution is to buy another pair!!! Are you for real!!! Why would I ever buy another pair if the ones that I own don't work!!! They didn't even offer to service them. I'm shocked but learned my lesson. DO NOT EVER PURCHASE A BOSE PRODUCT!!!!
