My pair has randomly stopped playing audio thru the right side. Out of the blue. I looked inside the earmuff and can see where one of the bars of the planar magnets is broken. Ive had this set for about 3 or 4 months with no issue until now. How can I get in touch with someone about getting a replacement or refund? Warranty? I'm so upset. I have been ever so gentle with these and only used a handful of times. Please help!!!
