How can i do this i really hate iTunes right now

i made some ringtones with audacity but i cant sync them manually i have to make it so my iPhone only syncs with my iTunes like automaticaly which i dont like cause i don't save music to my mac i just add it to my iPad iPod iPhone etc and delete the music from my laptop

is there anyway around this?

i really dont like keeping music on my macbook pro and the ringtones are korean so i cant buy them from the store -_-
