We're into the latter half of Amazon Prime Day, but fear not, there's still time to bag some incredible bargains. Even I am supremely tempted by this excellent Prime Day Bluetooth speaker deal on the Ultimate Ears Wonderboom 3, which is just $56.43 at Amazon US (was $99.99) and only £63.99 at Amazon UK (was £89.99) – that's the lowest price we've seen it on sale for, in both regions!
The Wonderboom 3 may not offer the most premium sound quality, but it's no slouch either. It's also a massively durable speaker that can float, has a great little 'Outdoor Boost' button on the underside and is an excellent value pick. It's cheapest in Active Black in the US, but even the more funky colorways are priced lower than ever before for Prime Day. Over in the UK, the cheapest model is the bold Performance Blue variant, which is my personal favorite – what a result!

The Ultimate Ears Wonderboom 3 is a great waterproof Bluetooth speaker which was already excellently priced. It doesn’t have audiophile sound quality, but you can buy two for a sound and stereo boost. This is the lowest price we’ve seen on this speaker, so there really is no better time to buy.View Deal

In our Ultimate Ears Wonderboom 3 review we highlighted its super-compact and lightweight design, which make it the perfect Bluetooth speaker for when you're on the go. If you fancy, you can even use a carabiner clip to hang it off your backpack, making it perfect for hikes or beachside walks.
Perhaps the main appeal of the Wonderboom 3 is its fantastic IP67 dustproof and waterproof rating, which has helped to earn it the title of best waterproof speaker overall in our guide to the best waterproof speakers. Not only that, but it has an elegant yet eye-catching design, especially in the more jazzy variants such as Hyper Pink and Performance Blue – sorry for gushing, but there's just so much to love here.
