My headphones are able to use a usb or aux port, and my laptop has a port for both. my headphones work with the aux cord in phone, and my computer works with earbuds in the aux port. my headphones work with my computer in the usb port, but NOT the aux port. this is the stupidest thing and it confuses me so much help. I hate taking the clunky usb cord everywhere and I got the headphones so I didn't have to get new earbuds every other month cause the cheap ones are so crappy.
