Best In-Ear, Wireless Headphones

[Kellz]

I'm looking for a solid set of wireless headphones, preferably in-ear. I currently have had the same pair of power beats for a few years now, and they're breaking down. i use them 5 days of the week if not more.

the main things i'm looking for are: wireless, lasting at least 4 hours. not over the ear, something i can use in harsher conditions. (i work in cold temps the majority of the time, sometimes a freezer).

i'm willing to pay a little more for the quality, so i thought i'd ask the smart people here.
