Which are better for bass?
I listen to Techno/R&B/Rap/Electric Music.
Do the SM3's have a detachable cord (I can change the cord connecting to the IEM's).
However, I needed more isolation.
Can you help me with my questions?
I have not receive the SM3 yet, so I don't know which Comply would fit. But I am guessing the P series of the T-100 series. And by the way, IE8 does not provide much isolation too. Just a tad more, but nothing compared to Etymotic.
Do over-ears feel uncomfortable?
Most decent earphones can be worn over the ear and probably preferred. You do get used to it however and it isn't bad after a while. I was hesitant at first because of glasses but it works fine now. It's automatic now with over the ear :)
