Which in-ear headphones are best for bass?

I am seeking a pair of in-ear headphones for sport, music and gaming, My budget is $200 AUD. I specifically want earphones that are bass heavy and sound powerful. I'm open to other suggestions too. Thanks!

I personally would get both becasue if you dont need the inear for sport and other things the overear is going to give much better sound for things like gaming.
