I have pretty small ears, these start to hurt my ears after wearing them for around 20+ minutes. They initially gave me a headache too but that seems to be partly fixed after 3 nights of burn in. While they do sound a bit better than my Apple EarPods (which shouldn't really be surprising), I really can't use these for long and see myself switching back after wearing them for too long.
LQDForceThat may be the case, but I don't know If I would spend more money on tips than on the headphones themselves. Not to mention they may still not satisfy me, IEMs might not be for me after all.
