I purchased this for my son so he can bring it with him and not worry about it getting wet. I have not tested the sound out yet as it is a birthday gift for him. It comes in a nice hard case. It almost like a wooden sunglasses case. It does have a strap that curls on your wrist so you won’t loose it. It’s like those slap bracelets that were popular in the late 80’s early 90’s. I do suggest holding onto to strap as I’m not to comfortable letting if just hang from my wrist.
