The OD-11 is every minimalists dream. It's the world's first cloud speaker and was shown off at CES this year. Made by a company called Teenage Engineering, the purpose behind the product is to have a speaker which gives fantastic sound quality but is completely wireless. It has a 100W amplifier which powers a subwoofer and a tweeter to cover the lows and highs. It has WiFi and Bluetooth 4.0 built-in so you can stream music from various services and devices. It of course comes with the standard 3.5mm headphone jack and an optical input.
