These speakers sound so good, they work at the advertised distance, and they look cool! There's no perceptible interference from other devices, and the sound remains remarkably steady even if you move the speakers from room to room. With great sound and awesome looks, you won’t regret getting these and adding more speakers in your yard, or room, or even hooking up you’re entire house! They're so convenient and easy to set-up. Who needs wires when you can get this at a price so reasonable.
