With an improved driver, this speaker delivers clear sound with strong bass so your music will be richer. Its sound diffusion processor makes it spread the sound out in any room so you’ll enjoy a better listening experience even from a device as small as this. At only 5 watts of output power, it is surprisingly loud given its size. The SRS-XB100 is very light and comes with a uniquely designed strap so it’s no bother to take with you or hook on your bag. Compact as it is, the speaker is capable of withstanding actual adventures in the wild. It’s IP67 water and dust resistant so you can take it to the beach or even camping without worrying about damage. The new UV coating adds extra strength, and protects the speaker from exposure to sunlight and normal wear. Despite its compact size, you’ll get up to 16 hours of playback on a single charge which means all-day and late-night listening without needing a recharge. The battery indicator keeps you informed when the power is running low so you’re never in the dark. Easy and convenient recharging comes courtesy of the USB Type-C port. For $33, you’d be hard-pressed to find a better deal for this level of sound quality. See at Amazon
