I First used it an it was 'okay' but then a few days later it feels like the battery life went down to 40 minutes. I could get it fully charged and at 1/4 volume and still have 40 minutes. And the buttons. way too loud. If you want to buy headphones with Bluetooth don't buy these. if you already have a good aux cord and want to get these, go ahead. The mic only works with Bluetooth. so if you already have a cable and mic, you might be able to use these.
