The Marshall Emberton II speaker is perfect to bring along to any banger. It has a vintage look with the stylish gold script logo and textured front, but that doesn't distract from its functionality. With an IP67 rating, it's water and dust-resistant, so you can even take it outside. Plus, its 30 hours of battery life is insane.

Right now, the May 2023-release Sony SRS-XB100 Bluetooth speaker can be yours for just $38 at Amazon (was $59.99) – that’s a huge 37% slashed from its list price and means it's gone right back down to the cheapest we've ever seen it!

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.
