Increased Treble/Sharpness with increasing the volume

[Hadi Ahmed]

Few weeks back i quickly got up and broke the jack of my sound card and my headphone pin also got bent
the sound card is not working now but the headphones are still working so i went to my computer store and bought a USB sound device since he told that Sound cards are outdated now so i bought it home and plugged it in so whenever i increase the voice the treble and sharpness of the sound also increase and funny thing is it is normal when the headphone is on medium sound but sharpness and treble increases when i increase the volume only from the headphone.Note this that if i increase the volume from PC it doesnt happen it only happens when i do it from the headphones
it's quite annoying
also that my headphone pin got bent and didnt straightened it

Not all sound devices are created equally. I don't think there's a solution to this other than buying different hardware. While USB audio devices are common these days, they can vary greatly in quality depending on their hardware and drivers.
