Waterproof Bluetooth Speakers MARSEE Waterproof

Included with the speaker is a short micro-USB charging cable, aux cable, and user manual. The speaker is constructed of metal, plastic, and a hard rubber with a rubber wrist strap at one end. On top you will find the mic, power button, volume/skip buttons, and play/pause/answer/end button. Opposite the wrist strap is a water resistant cover with the charging and aux ports under it. I have not used the speaker to dead but I have used it for over six hours with no problem. As for sound this little speaker gets surprisingly loud and remains clear until it gets to almost max volume. Bass is lacking a little but that is to be expected with its small size. Overall it is a great little speaker.
