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.

Amazon has the Sonos Era 100 speaker, the much-improved successor to the Sonos One, on sale for $50 off. Prime Day also lets you save big on a pair of Sonos soundbars: the Beam (Gen 2) and Ray, which are up to $110 off.

A speaker that offers dazzling clarity and rugged convenience for less than $50 is hard to come by, but this little speaker is ideal for those looking for on-the-go listening. Even if you aren't the outdoorsy type, the IP76 waterproofing means that you don't need to worry about water damage in the shower or accidental splashes in the kitchen.

Amazon has knocked $180 off the price of the Beats Studio Pro headphones in a limited-time deal during its "Prime Big Deal Days" sale. Shop it here.

Not 48 hours before the writing of this piece was I entertaining a party with one of the very speakers on this list — the Soundcore X600, which is now $149 at Amazon — a $50 saving. It kept a group weekend in the countryside going with some incredible loudness, excellent sound, and top-notch battery life.

If you’re going to buy a Bluetooth speaker on Prime Day, get the Sony SRS-XG300 that’s now on sale for $148 — that’s a whopping $202 off its MSRP and the best price we’ve ever seen for this particular model.
