We're only a few short days away from Amazon's next big sale event, Prime Big Deal Days, which means we're already starting to see epic deals on some of the most popular devices. Whether you're shopping for yourself or trying to get an early start on your holiday shopping,

Smaller yet useful tech accessories — batteries, cables, phone cases and so on — are what keep the big ticket items going. And Amazon’s Prime Day is a good time to stock up on them. Only problem is, not everything on Amazon’s site passes muster,

The Sony SRS-XE200 X-Series Bluetooth speaker is 48% off ahead of Prime Big Deal Days. It comes with a corded strap, making it easy to tote around on your adventures. With a IP67 rating, it's water- and dust-proof, giving it a rugged build. Not to mention the 16 hours of battery life that keep the party going all day.
