Sure, wireless speakers aren’t all that new, neither are outdoor speakers, but a smart combination of the two brought to you by Sharper Image, well that’s nearly a work of art. They use 2.4GHz signals, so you’ll have to make sure it doesn’t interfere with any of your other gear.
Other than that, all you need is an audio source that uses a standard headphone jack for its output. You can also by a second speaker, to make it stereo, its not another one of the main unit, it’s a special auxiliary speaker.
The initial setup, without the additional auxiliary speaker, will cost you $199.95. The auxiliary speaker is an extra $99.95 and looks to be another speaker like the main one. Both run on AC with an adapter that comes with it, or you can use 6 D batteries.
