This speaker bar is as bad as it sounds. Reviews from other sources indicate that the default mode is Bluetooth when it's on, but my device seems to default to line-in, so I suspect this has been fixed in a later release. However, GPX doesn't list power consumption specs anywhere as they may not know about audio or USB. USB is the power source, but the USB adapter is not included. USB adapters vary in output current so speaker and amplifier performance is unknown depends on what source you are using for USB. The audio output is weak, distorted at low, mid, and high frequencies, and has little to no bass. Unfortunately, my TV's built-in speakers, which aren't very good, produce better sound than this.
