Sony XB100 Compact Bluetooth Wireless Speaker

Waterproof and dustproof, this portable Bluetooth speaker is great for golfers on the go. The strap can easily hang from a bag or pushcart and there are large control buttons on the side that make it easy to change the song or volume. It's extremely compact in size, but a sound diffusion processor inside the speaker creates expansive sound with a ton of clarity and boosted bass that's impressive for such a small speaker.
