Funny enough, this is a question I get whenever I instastory from the gym where you'll see me always wearing one of two pairs of wireless bluetooth headphones. Rich and I both have a pair of these wireless headphones which we ordered from Amazon months back and absolutely love them. They're water resistant so you don't have to worry about getting sweaty, they have a really long-lasting battery life (8 hours), the sound quality is excellent, they have a microphone so you can take calls on them, and best part? They're only $20! I also personally really like having the earhooks when working out (as opposed to my Jaybird wireless headphones which I also love!) because they provide so much more stability when I'm running, jumping, etc. I never have to worry about them falling out during my workout. I keep the Jaybird pair in my bag for using on my commute, at the office, etc. when I want something a little less conspicuous.
