Looking to upgrade from KZ ZSN Pro X need to be the same or easier to drive via phone

Hey guys, I have been using a pair of KZ ZSN Pro X for ages and would like to upgrade to something better i use the spinfit cp145 tips and play music through youtube on a huawei mate 10. The problem i have is that the volume level on other iems is too low and i cannot use a usb c amp / dac as my phone does not allow usb c audio. I have tried a pair of CCA CRA and Moondrop Arias but the volume was too low and i sent them back. Any recommendations would be welcome for a price around or under $100 AUD. Thanks
