This is a great little speaker. I’m returning it because the volume control isn’t fine tuned enough for my liking. You have to push the volume _/+ buttons for a few seconds for the volume to move. By the time you realize the volume is changing and you let go of the button, it has moved 10-30%! I need to go up one click at a time. Oddly if you just touch the -/+ button, then it moves to the previous/next song!? I’ll use that 1% of the time and volume 99%. Most other devices use the “volume upon touch”, and holding for 3 seconds will move the song/track. So to me, it’s backwards and unusable.The sound is very good and it “feels” nice and heavy and solid in the hand. Looks great too. I got the black model, although when I called Planet Audio/Lynx, the tech told me all of their models do volume the same way. Ah well. A different brand for me then.p.s. When charging via the USB connection, the blinking light will be red. The only way to know if you are fully charged is to turn the unit ON and the charging light will turn green when fully charged. Otherwise if OFF, then the red charging light will blink forever and you won’t know if you are charged or not.
