Sony has always been known for their design, and this device is no different. Portability is the key for this device and they nailed it. The device is small and round, think Billiard ball, and not too heavy. It is covered in a kind of matte plastic, which gives it a nice rubbery feel. I loved the material. Sony has also made it available in black, white and blue. It also comes with a bag, so you can carry it around with you.
Battery life is listed as 5 hours of continuous use. This was about right in practice, so long as you remember to turn it off when you aren't using it, which is easier said than done in this growing wireless world.
Now for the important part, sound. The sound from this device can be described as adequate. For the size, it gave decent sound, but nothing earth shattering. Bass was non-existent but audio was quite clear. The volume was loud enough in an ambient environment, but start adding background noise and you start to lose it. Walk further away and you lose a ton of clarity. Racking up the volume to max just made things worse. The audio took on a tinney sound, common when the speakers are being pushed past their max, which forced you to bring the volume down. As a result, I would find it hard to recommend this to anyone for anything other than music our other audio in quiet enviroment, as long as they don’t mind the lack of bass.
What it comes down to is how you will use the device. There are two camps that may want this speaker, one for sharing, and the other for portability. I honestly think you should only get it if you fall into both of these. There are some pretty high quality speakers out there than can spit out good sound with great bass, they just aren't going to move around as easily. But if you are the type of person who takes their music everywhere and doesn't necessarily share, why aren't you using headphones?! If you want both, then this device is actually pretty good and the price tag isn't too bad. I complain a bit about the sound, but to be honest, it’s pretty good for a device this small and portable.
Currently you can pick them up at any Sony Store or online at Sony.ca for $79.99 (currently on sale for $69.99), but I did find them at Walmart for cheaper, so if you look around, you can probably find them at other places too.
