Purchased these at the beginning of January....I was happy with the sound quality which was very good and comparable with Bose and Beats but after only 1 month the volume started to dwindle now I can barley hear out of the headphones at max volume the left earbud also quit working...I will be returning these as the overall quality of these is terrible....Update I took the headphones to best buy and they will not accept the return...apparently they don't guarantee the products they sell and told me pretty much its not their problem and I need to reach out to the manufacturer
