The New Sony SRS-X9 Speaker ($699) does everything you come to expect from all bluetooth speakers, but it comes with a little something extra. Just like almost every other bluetooth speaker can use your smartphone, tablet, or PC to stream music to the SRS-X9 via bluetooth, wi-fi, or USB-5. That music is delivered to seven speakers (3 tweeters, 2 midrange speakers, and 2 woofers) to provide some of the highest quality music. But the little extra the SRS-X9 brings is its ability to support lossless FLAC AUDIO formats up to 24-bit/192kHz resolution and high resolution WAV files, so you get maximum audio detail in every high quality track.
