No bass in brand new headphones

So I just bought a brand new pair of ATH M50x headphones, and for the fist 30 minutes or so of using them they worked a dream. I turned my Inspiron 15 5000 off and later went back on and the headphones still worked. I unplugged them and plugged them back in and all of a sudden there was barely any noticeable bass coming from them. They work perfectly fine with any device like my phone and iPad, its only my laptop that there's no bass with. I tried resetting the audio driver properties to default, I uninstalled and reinstalled the Realtek Audio Device, I restarted my laptop multiple times, and used different AUX cords for the headphones. I've had 0 luck, in fact its gotten worse. Can someone suggest anything new that might help? Thanks
