Had this for a month now. The sound is incredibly good, plus it has knobs so you can adjust treble and bass to your own liking. Turn the volume right up and no distortion, no loss of clarity. 18 hours easily from one charge. Headphone jack and input jack if you don't want to use bluetooth. I am rapt in this speaker, it is better than any of the other (equally expensive) ones I have had. It's worth every cent.
