If it's only certain MP3 files you might want to identify WHY those files have too much bass. THAT would have happened when they were created. It's not a speaker's fault how the music sounds. Then there's your PC or whatever other device it passes through. Lots of opportunities for MALadjusted sound. GIGO.

They are disposable items, very poorly designed and bad quality. I had a great set early 90's, they failed so I bought another set around 2010. The hissed even when turned off so I donated them!. I bought a pair of Bowers and Wilkins MM1. A whole different ball game in quality, sound and a lifetime warranty. The problem is getting into them as they have secret hidden plastic catches. Go around the seam in the body with a spudger to look for the catches.

A constant low hum is a sign of a power supply issue. You need to check the capacitors that filter the ripple current and you need to check the diodes that convert ac to dc
