The ports are for the bass that go in the back of the body, the treble uses a tube that goes in the front which your tip then goes on. It's a combination of the two that you can tweak to your preference. Usually most people tend to just find a combination that they like and go with that.

I think i'll never buy expensive phones ever again... wasted money.

need to buy more of them. Seriously! Why don't they make all the tips with that material? I only got 2 foam tips and like 14 rubber ones
