Bluetooth Headphones or Earbuds

I'm currently looking to purchase a set of bluetooth headphones or earbuds to use with my Evo 4G LTE. I did a quick search on the website and didn't find any reviews or any forum post about them.

Seems to be a product that isn't worth mentioning at this point. Maybe the products in this market are not quality enough yet or maybe just looked over. I went on Amazon and saw some products that had a 4 star and higher rating in the $50 range, but I wasn't really sold on any of them. I'll list a couple examples below.

Anyways, I want something to used while I'm working out and not have a cord that gets caught on everything. Below is a basic list of criteria that I have.

-I prefer earbud style but I'm not completely closed on the idea of headphone style

-needs to be good for being active and not fall off all the time

-of course sound quality is always important

-would like to stay in the $50 range but would be willing to go up to $100 for a really nice set

Maybe another option would be buying a bluetooth adapter that I could plug my current earbuds into. If you know of anything like this that works well let me know as well.

I appreciate any suggestions.
