If you're looking to play music from your computer there are a lot of options. Just find a device that has a Bluetooth receiver, Airplay, or can have either of those added to it easily. What to buy depends on how much room you have and if they are supposed to double as your computer speakers. You don't want to have the sound from your computer coming from some weird angle, I've done it before and it drove me nuts. A good set of book shelf speakers or studio monitors are probably what you're looking for. Careful how much you spend because if you've never had quality audio equipment before you might find yourself with an expensive new hobby.
