The M6 pro is okay. They hurt my ears too much to use long term and will eventually give me a headache even with the me buying all the optioned foam buds to try. The sound is decent enough for me to turn off the audio enhancer on my phone (viperforandriod or the lineageos equivalent). the only thing I really like is the ability to switch to another wire because I destroy them pretty easily other than that a pair of 25$ xaiomi pro earbuds beat them pretty easily in sound and feel.
