A:AnswerYour in luck because we at bestbuy don’t sell left or right side by itself. So if your missing whatever side then eBay has the sides your missing, check them out...
A:AnswerI personally haven’t had an issue when I work or while I’m working out just make sure to conduct general cleaning on them once and while so they stay clean. I’m not sure about a manufacturer warranty but when I purchased them from Best Buy I think I got warranty when I purchased them.
