What are the best in-ear headphones for about $50?
I listen to all kinds of music, mostly hip-hop. Which ones would be the best for me?

I bought these.

Sound as good as my Beats Studio, just more sound isolation with the Beats.

Monster Turbine

Actually, I just recently got a gift card so I'm willing to spend more.
I've been looking at the monster turbines. Are those good?

I have been using the Shure SE115 for a few years. It is excellent. US$64.95 on Amazon. You may probably be able to get it at a lower price.

Worth a look – reduced at Amazon to $50.
