Query: Static makes these useless

I want to like these and I hate to have to deal with not liking them, but at least one of them crackles and pops incessantly to the point where you have to turn it off. I use them in our shop to create a pleasant atmosphere and nothing is more grating than crackling speakers! I love the idea of them, but if the sound isn't clear, I can't use them.
