The Altec Lifejacket is an lP76-rated super-solid-looking, bulky waterproof portable Bluetooth speaker housed in heavy-duty rubber skin to keep out sand, dust and dirt.
With looks like it could take a knock and bounce back from a big fall, this is one sturdy speaker unit.
It has two 2-inch drivers protected by grilles, as well as a passive radiator for the boom.
A silicon hatch covers the USB charging port and the 3.5mm input socket.
According to the gadgetreviewed report, it can float but while it does so the sound suffers.
It offers 16 hours playback from a full charge, price TBA.
