ASWY's product, simply called the Floating Bluetooth Speaker, has three watts of output, five hours of battery life and Bluetooth 4.0 support. You can also plug an audio source directly into the 3.5mm input, and, since there's an integrated mic, you can use the device as a speakerphone as well. Like with OM Audio's version, you'll need to use a powered base to keep the speaker in the air, but it'll operate untethered as well.
The base also includes an integrated USB port, so you don't need to use a secondary adapter to charge up the device (though you can if you like). ASWY reps expect distributors to sell the speaker for $149 beginning this November.
