What??? That is not a boom box that I hear? This speaker from SoundPEATS is a Dynamo! I have a few little portable speakers which are fine if I am in a quiet room but in a party atmosphere they are not really loud enough. This little waterproof speaker is loud, the sound is clear and quite precise. The fact that it is waterproof make it great for outdoors, camping, hiking, at the beach or outdoor barbecue or pool parties.
In addition to being waterproof, the speaker is shockproof. It has a bumper all around much like the Cell phone bumpers.
