Its even loud enough for decent background music during backyard parties. 5-8 for my 3yo son who loved them from the moment he tried them on. Something to consider if looking to buy these. They actually run what I’d say is a full size larger but that’s perfect. Always wanted something like this in the shower, but I just found out that there are waterproof speakers out there. Overall: I believe this device is VRs best shot to become mainstream. I transformed my barbell into a pull up bar attaching it in the top of my squat rack! Because theyre RGB, white is really just a very light blue. I was surprised too because I have narrow feet but unfortunately I had to return these. I got so made after month 2 when I was on the third row of hooks and it was loose.
