Regarding in ears.

Hey guys
So im considering buying some in ears :)
- When im djing at clubs the monitors are often directed to the dance floor or sometimes they are directed directly at me (the dj) but at the same time the dance floor.

When im hired at private gigs i have my own sound technicians so i set the speakers/monitors up so i stand behind all the sound and the sound can go though the room and not hit the wall and directly back to me.

I dont use any external monitors i mix in my headphones at it works perfectly i recorded a whole set of 4 hours from a bar and it was smooth.
So i would like to save my hearing in the future
but any suggestion what to look for when looking for in ears?

i have been looking at theese two:
