Bluetooth Speakers?

It seems like being able to listen to your itunes through speakers while holding the Ipad working on something else might be cool? Are there any manufacturers currently making speakers like this?

I must be out of touch not having seen that before. Either way it is pretty cool.

 

I am shopping for a device like an I pad that can be a phone too. Will this work on the I pad device? thanks
