EDIT: The only reason why I still had it at this point was because I could use it with other apps. However, now that my Spotify Subscription is cancelled, it doesn’t work with anything. It’s mildly infuriating because today, I can’t still use it with other apps like I was able to yesterday.
Please don’t make the same mistake I made. No one should buy this.
Even USB-C is lacking as far as volume is concerned. I recently had to upgrade my 8-year-old phone to a new model that only has USB-C and no audio jack. My car has an aux-in plug and I got an adapter for the new phone, but the max volume is only about half what the old phone was. How the fuck am I supposed to destroy my hearing with USB-C?
When playing music from USB-C the audio precessing is happening in the adapter, not the phone. You may want to get a different/better adapter and that should solve your problem with low volume.
This one from Amazon sounds good, gets crazy loud, and is very inexpensive:

The limitation on volume is mildly irritating, but I only notice it every once in a while.
