I found the battery state using Wireshark, however the value doesn't update automatically. The Audeze app sends several SET_REPORT events, which probably are the ones that update the value, but I was not able to replicate them (it even started sending wrong values on the GET_REPORT).

I'll attach the Wireshark log in case anyone with better USB notions than me can work it out. I opened the app while the headset was charging and it went from 97% to 99% then I stopped it.

In frame 2008 the hex at 002e changed from 0x61 to 0x62 (97% to 98%).
In frame 4300 the hex at 002e changed from 0x62 to 0x63 (98% to 99%).
