I bought the Topping DX1 and I am happy with it so far. How would you suggest I equalize the headphone? My Legion laptop comes with Nahmic in which I always have the effects turned off.
Download Equalizer APO for free. A system-wide equalizer for Windows 7 / 8 / 8.1 / 10 / 11. Equalizer APO is a parametric / graphic equalizer for Windows. It is implemented as an Audio Processing Object (APO) for the system effect infrastructure introduced with Windows Vista.

Some people seem to recommend
Equalizer APO.
I would suggest you try Equalizer APO without the optional Peace GUI.
The standard EQApo GUI does just fine and has some advantages.
Your Laptop's Nahimic software should cease to function when you use USB out, so you shouldn't have to worry about that.
Attached below is a PEQ preset for the K92 which I created using
https://autoeq.app/
It's a super handy tool, highly recommended.
To import it into EQApo, open the Editor, add an "Include->Include configuration file" block and load in the txt file there.
You may have to move the txt to the appropriate folder to make it readable, the software will tell you.
One thing I recommend you do is to delete the first preamp line from the txt, then manually add that preamp back into EQApo with the identical preamp value. It should look roughly like this (different preset shown here):
That way, you can easily turn the EQ on and off without a jump in volume.
Makes judging the EQ a lot easier.
Your Peak gain should never exceed -0.0dB:
If it does (the number will turn red), simply reduce the preamp gain.
