Designed to deliver surprisingly powerful sound for such a compact speaker, the palm-sized Go 5 portable Bluetooth speaker from JBL lets you stream your favorite playlists almost anywhere. The Go 5 is IP68-rated to be waterproof and dustproof and is also shock-resistant, making it ideal for outdoor use. Carry it to the pool or use an optional carabiner to clip the finger loop to your backpack. However you carry it, the Go 5 is ready to play music for up to eight hours per charge, with another two hours when you engage Playtime Boost.
