I live in Arizona, and in my 15 years out here I have went through about six CD/Radio players I have had out on bar by my pool, the heat and the dust destroyed every one of them. Was looking for wireless speakers for my Bose radio, and they don't exist, in fact the wave radio I have won't even let you hard wire to external speakers.
Was toying with the idea of buying another wave radio to put outside, but didn't want to see that one go south too.
One of my son’s tuned me into getting a Jawbone Jambox, it’s a wireless rechargeable speaker that works off of a Bluetooth connection
I checked out the models and the smaller one’s for a single room didn’t cut it, then I checked out their larger model, the Jawbone Big Box.
It’s bigger yet very portable, best thing is, it is as clear sounding as a Bose and has just as high volume and sound out put. It is rechargeable, takes about 4 hours, yet the thing will play non-stop for 20 hrs on a charge.
Since it is portable I don’t have to worry about leaving it out in the heat and the dust, and since there is no CD slots, there is nothing for the dust to enter anyways.
When I want to use it, I simply take it out to the pool with me, put it on my patio bar in the shade, fire it up and then link it with bluetooth to Pandora on either my cell phone or my tablet. It has more then enough clear crisp volume to fill up my back yard. Paid about $300 for it a couple of years ago, and I use it almost every day in the summer while in the pool, it is absolutely great!
