The sound is very good and decent price point. There is no app to control the settings. And THE SPEAKER HAS RIDICULOUSLY LOUD SYSTEM SOUNDS. When you turn it on it plays a pointless Seinfeldesque bass riff and then, when it connects to anything, shouts 'BLUETOOTH CONNECTED'. Turning it on in public is embarrassing, but this is a minor concern. However, if you listen at night or in bed, when you turn it off or it turns off after it times out, it plays a different bass riff at 3/4 volume to tell you it is shutting down, waking everyone up. Terrible product design but 2 stars because the sound is actually quite good.
Great Sound! Unfortunately it only lasted 2 weeks, before the speaker stopped working completely. It would turn on/off, but just wouldn’t make sound anymore. Disappointed.
