Sony has unveiled the NAS-V5 and NAS-V7M Walkman speaker docks which will sport Wi-Fi connectivity, allowing you to enjoy the benefits of Internet radio thanks to a variety of channels, while 32-bit DSPs ensure you will be able to enjoy crisp and clear audio quality. Apart from that, you can expect to enjoy standard AM/FM radio features, an AUX jack and a powered USB port. Since these are from Sony, they also tout a Walkman dock for that added bit of value. The $535 NAS-V7M sports 16GB of internal memory that makes it a snap to rip your audio CD collection onto it with the touch of a button, while the $428 NAS-V5 lacks that. No idea on whether this will arrive anywhere outside of Japan anytime soon.
