Sony brings Bluetooth connectivity, NFC support, and good sound to a sub-$300 speaker that competes with the big boys. The SRS-BTX500 is intended to be a portable speaker, and it is, but CNET says "it's probably not something you want to be carrying around in your luggage" due its weight. The weight leads to some durability, though, with Wired saying it's "ruggedized a bit to handle the beach or park." The issue of weight is offset when you start to listen to music, and T3 says "it manages room-filling hi-fi quality sound with ease." Wired was just as impressed with its sound, saying it "sounded way better than other mid-size speakers." At $269 it's priced competitively with the similarly sized Big Jambox, but the Big Jambox doesn't have NFC for quick pairing. If you're ok with a portable speaker being four pounds, and like the idea of NFC pairing then put the SRS-BTX500 at the top of your list.
