Headphone volume is way too loud in windows 10 even with an external usb sound card [duplicate]

I had the exact same problem with my DT 770 Pro headphones. I could maximum have Windows' volume on 2/100.

I use this software to lower the volume: https://sourceforge.net/projects/equalizerapo/

I installed it and set the gain to -50 dB.

Now I can use the whole range from 0–100, which makes it a lot easier to set the volume correctly.

Does the problem only occur with these particular headphones? It's possible the headphones have their own volume controls, although I can't imagine it being that loud at level 1.

Try a pair of plain earbuds and see if the problem persists.

Another thing to keep in mind is that sometimes there are multiple volume controls on windows depending on what's installed. The sound card itself may have its own set of volume controls, so check for any programs related to the sound card.
