I have both ( different colours) and they are both good. It's harder to find authentic top ones but it can be done. Just pick one at random and when you can get the other. If I were you, start with the bottom.
i have the top ones and they can get heavy but if you put the right one in your left ear and then the left one n your right ear they wont fall out. but you should get the bottom ones because they stay in your ear
I had both the top ones and the bottom ones and I think the top ones look better but the bottom ones are much more comfortable; the top ones were quite heavy and they kept on falling out of my ear, and they have a thick cable
