If its one thing that annoys me about them, its there super hearing strenght.I have muffle boots on ,sneak to about 80 and they still manage to detect me

Do they see you? Also remember, muffle-enchantment doesn't eliminate movement noise.

Well depends on what you call seeing.Yeah they seem to see better in the dark then everyone else.The rest of my enemies i can basicly stay in front of them and still they dont see me.It also happens when i try to sneak up on them, whenever i get to close from behind they start being aware of the danger.

Kinda ruins the point of my super stealth character.

What sneak perks have you picked?

The Forsworn rarely catch me. When I sneak past a couple of Forsworns and see a Forsworn Briar-Heart, I pickpocket the Briar-Heart's heart, and he automatically dies..
