I was wondering what the pros and cons of IEM's vs. Over ear headphones. I use them mostly at home but I also do not want to use the same pair on the go. For IEM's I was looking at Sennheiser IE80, Shure SE 315 Westone 4 etc. My budget is around 300$. For Over Ears I was looking at things like the Sennheiser momentum. My ears measure 60 mm in length. My MAIN ISSUE is comfort. Are IEMs comfortable and will wearing them for around 3-4- hours (not continuously) damage my ears as I am essentially sticking things in my ears. Thanks and a few other recommendations at this price point would be nice. I like to listen to rock, pop, some classical, Preferably, I do not want a flat sound signature. I am not that much of an audiophile and like some more bass.
