In the market for a smaller bookshelf style music system, but you don't want to break your savings? Enter the Sony one here. It's a small shelf system with 50 watts of power, CD, AM/FM, USB, Bluetooth, and NFC. In fact, it's pretty much one of the few if not only shelf systems that has Bluetooth and NFC integrated. With the rise of smartphones becoming our music storage and playback, this feature is welcome.
