Being a musician and sound engineer can be a curse. Any hint of distortion, buzz, or imbalance will stand out. After reading the reviews of many Bluetooth speakers, I chose RIENOK. I was pleasantly surprised by the purity of the overall sound as well as the presence of bass. I also liked how quickly it connected to my iPhone. I originally bought it for my workshop. But because it works so well at higher volumes and is waterproof, I ordered a second one for my backyard stereo effect. I had the speaker turned off for over an hour and the volume was over 60 decibels, so I can't confirm battery life other than all four power lights were still on. I read some reviews complaining about short battery life and annoying lights. If you really read the manual you can turn off the lights and most likely save some juice, although there may be some faulty equipment in there.
