Hi I got a pair of your guys Bluetooth headphones with the model number or something being BE1001 and I was using them one day and the right ear bud stopped working like I can't hear anything from it but I can hear out of the left ear bud, if you fiddle with the cord from the right ear bud to the controls you can hear out of it for a second. So I was wondering if I could get a replacement pair (I don't still have the box) or get a refund for them
