Pros and cons of wireless speakers

Can anyone give me the pros and cons of wireless speakers as far as PC gaming goes? 

Not sure about typical power supplies, but mine interferes severely with anything wireless around it. My mouse and keyboard wouldn't work, and my wireless card drops connection every few minutes. I'd image it would have very noticable effects on wireless speakers.

I'd say the cords are worth the hastle.

Thanks for the info :)
