This bluetooth thread on Head-Fi is a good place to start,
though they don't seem to have much recent discussion of USB-C dongles.
The Verge reviews one pretty well, hopefully others here can chime in...
My experience has been that wired > wireless across all things digital,
and in audio the biggest factor is the drivers - where the sound is generated,
and a dongle will give you the greatest flexibility in auditioning IEMs & headphones.
Are you rooted? Viper4Android and other EQs make a big difference without adding hardware complexity.
This is the best option if you are rooted. It has great sound effects and works globally for all apps.

It also supports convolution equalizers like these. They equalize your headphones to sound as neutral as possible, in a way which isn't possible with a typical graphic equalizer.
Just stick with one.
Since you're posting in r/androidroot I'm going to assume you are rooted, and I recommend using Viper4Android as it's more than just an EQ.
How do you feel about rooting? I own over a dozen pairs of headphones/IEMs/earspaeakers/whatnot, and my daily drivers are a Pixel 3a and Jabra Elite 65t truly wireless.
I'm rooted and have Viper4Android sound mod running, so I can get exactly I want in my earholes.
I love mine, but if you're going to use head/earphones, I think Viper4Android is mandatory to tweak the sound,
which also means rooting.
The process is not nearly as tricky as in the past, and Magisk is a big part of that.
After quite a bit of fiddling (goes with the territory), I found a Viper4Android that works on my rooted 3a:
ViPER4Android FX 2.7.1.0 by Team DeWitt which installs from an .apk.
It doesn't seem to have profile saving/loading, but positive feedback should help that.
The main thing I use is the Surround mode(s) to open up the stage for IEMs

You'll need to root your phone to use it. This one is the reason why i cannot live without root. After you've installed, play with the settings and you can feel the differences.
Damn. See if you can get AI to work with a point-click on some other switches, such as in Settings. If it works, then it's just AudioFX.
Aside: VIPER4Android is way better.
