Hi @adrianakb19 ,
Try pairing the headphones with another phone or tablet etc and check whether it performs OK using BT.
If it still doesn't work properly, since you have only had them since August and as the manufacturer offers a limited 2 year warranty on the headphones, I suggest that you consult the warranty statement that came with the headphones as to what you have to do to make a claim for a warranty repair, replacement or warranty credit with the Skullcandy online store.
If you cannot find the warranty statement, here is a [https://www.skullcandy.com/customer-service/warranty-information/warranty-information.html|link]
