Looking for what speakers would be best for PS4/Monitor set up.

I need some speakers for my PS4, I have a monitor that doesn't have the ability to produce sound. There also is no port for a speaker to go right in the monitor, I know about the little attachment for the PS4 to have a speaker plug in through that way and that's probably what I'll do. What I really need to know is what is the most reasonably priced, good quality speakers I can get from anyone's experience. Thanks.
