Sony is claiming its spot in the crowded compact Bluetooth speaker market. The new SRS-BTV5 is roughly the size of a billiard ball, and what the 1.2-watt speaker might lack in big bad base, it makes up for with functionality. It can connect wireless to any Bluetooth A2DP compatible audio device, and Sony has added NFC functionality to simplify the pairing process even more. A built-in mic and volume control makes it possible to use the SRS-BTV5′s as a speakerphone. One single charge gets about five hours worth of playtime, and the device recharges via a microUSB port hidden beneath an access panel. After it premieres in Japan, Sony will be eventually releasing the minuscule speaker globally.
