Windows 10 headphone volume abnormally loud

Whenever I plug any headphones into the 3.5mm jack, I have to turn down the Windows volume to 2 for the sound to be bearable. I also do not see a 'Headphones' when I click on the sound icon in the bottom-right corner, only 'Speakers (Realtek High Definition Audio)'. These problems do not persist if I use Bluetooth. I saw many people online have the same problem, but I haven't found a solution. I have checked for updates for the audio driver not there were none.
