USB-C implies Android—Wavelet is an EQ app that works with all music players and you can add bass & dampen treble to your heart’s content. Some apps like Spotify also have a basic EQ built into them.
Dongles aren’t supposed to alter the sound profile, and even if they did it is of limited usefulness if the effect is something that can’t be tweaked at all. It’s just DSP at the end of the day, there’s no benefit to doing it blindly in the dongle rather than via a controlled EQ setting.
Portable audio related purchase advice may also be asked in r/HeadphoneAdvice but please familiarize yourself with their rules first.
What questions are considered purchase advice?
A request for product suggestions, comparison requests, or opinion requests fall under the purchase advice rule. These can often be found by searching first.
Any suggestion or comparison request pertaining to headphones, IEMs, DACs, amps, or other accessories should be directed to the purchase help thread or r/headphoneadvice.
Asking the subreddit to help make a decision to buy a product does fall under this rule (e.g. "should I get dekoni pads for my HD650?").
Why does this rule even exist?
In short, this is a large subreddit with a high volume. We want to help, but it's important to keep things organized to keep the sub fun. Thanks for your understanding.
I'm certain that my post wasn’t asking for product opinions or purchase advice!
Thanks for reading the above and making it this far.

EQ is not an options?
