I purchased Ausounds wireless earbuds through Microsoft Direct Buy on 11/16/23 as a Christmas present. We realized the week after Christmas that the left earbud does not work. Ausounds' tel number in LA is not their number and they have not replied to my emails. They don't seem to be legit. Microsoft will not refund as it was over 30 days. I just learned that Unbeatable Sale is the seller behind Microsoft. Requesting refund. If you want the earbuds, I will gladly mail it if you include the postage in the refund.
