Really great sound, mediocre battery life

Sound is really great, but the battery life falls short of the advertised 8 hours. After an overnight charge, I got 5hrs 8min at medium volume. The battery also seems to lose charge quickly when not being used, which means I have to recharge it frequently even if hasn't run for 5 hours in total between charges.
But again, the sound is fantastic. Even with the crappy battery life, I'd probably buy again.
I would recommend this to a friend!

Nothing but the Bass!

Bass is excellent. Overall sound is good. If you like throbbing dance music, this is it.

Best Speaker

This is by far an away the best Bluetooth speaker I have ever owned. I have comparable brands but this speaker is amazing. My only regret is I don’t buy two. When I went back for a second one they were sold out!
I would recommend this to a friend!
