My sound is much better all of a sudden?

Didn’t know where else to post this…Reddit might’ve been better but I tend to get better/faster responses on gaming forums but anyway

I recently switched rooms with someone in my house and obviously had to unplug my PC and transfer everything to the other room…after plugging everything back in my sound seems a lot more crisp and louder…I usually set my PC volume to 50% but ever since the switch I had to reduce it to 30%. I’m not sure why this happened I didn’t change anything…I even plugged everything where it was plugged originally. I’m not complaining at all I’m just dumbfounded as to what actually happened
