Recs for bluetooth/wireless heaphones for workign out

OnTheGround

I'm looking for some wireless headphones for working out, preferably under $50. I would prefer in-ear ones, but am open to anything that will stay on my head while I work out. I do about half weights/lifting and half cardio.

I bought these and I love them.
