The Nokia Portable Wireless Speakers, announced at Build 2013 besides the 930 and 630 have officially gone on sale. You should be able to grab one of these little bests from a nearby retailer for €39.
A quick reminder of the specs of these little speakers, it has a 15 Hour playback battery, can sync via Bluetooth/NFC as well as connecting through a standard 3.5 mm headphone jack; and is only 38 mm high, pretty cute.
Color preference anyone? I’d certainly love an orange one to match the 930 I plan on buying.
