Your best adventures call for a sound­track, and ECOROX provides one. A portable and durable Bluetooth speaker, it goes wherever you go, standing up to dirt, sand, drops and dunks. You can mount it on your surfboard, tent or bike. You can even plop it in a pool or leave it by a lake, because it’s waterproof and it floats. At less than a pound, it’s also small and light enough to carry in your backpack. Despite its pint-size frame, it delivers plenty of oomph. We’re talking crystal-clear sound and 10 hours of battery power. Its novel design features a rubberized exterior that protects the Ecorox from daily bumps and bruises, making it a rough-and-ready traveler. $130, www.ecoxgear.com
