Sound good to you? Read the Ultimate Ears Wonderboom 3 review to find out more about it. In an emergency, you can also still charge your phone from the Wonderboom 2, as long as you have the right Micro-USB cable which I doubt many people will. It doesn't sound better than the normal mode, clearly, but it 'cuts through' better and is a handy addition. In our testing, we were impressed by the sound quality but we really enjoyed the Outdoor Boost because it makes the audio a bit less bassy and a little more shrill. Being IP57 rated, it's also well protected against grit, saltwater, dust and beach-side sand, so long as you keep the USB charger cover in place. It's just a straight-up Bluetooth speaker but you can pair two of them together either in stereo or dual mono. Clearly meant to be taken to wherever the party is, it's also fully waterproof – in fact, it even floats.

The Ultimate Ears Wonderboom 3 is undoubtedly the best cheap Bluetooth speaker on this list, combining good sound with an ultraportable design and effective 360-degree audio. It's an absolute champ and deserved winner. That'll quickly explain why it won the T3 Awards trophies for Best Portable speaker in both 20. Here's our full B&O Beosound A1 2nd Gen review.

The build quality can certainly take a tumble, and is dust and waterproof, for lighter dunkings. And, being a B&O speaker, it's also an object of desire, and is available in a great range of colours, with new ones added to the range over time. There's another smart trick here too, though – you can even use Alexa from the device, despite it lacking Wi-Fi, thanks to the Bluetooth connection.

And it follows B&O's usual MO of having quite a neutral sound out of the box, but you can use the app to customise the audio – we at T3 like to push up the bass of B&O's products a little, and that's so easy to do and then save as a preset. That's no surprise when it comes from Bang & Olufsen, of course. The Beosound A1 v2 finds its way to the top of this list thanks to sheer audio quality for the size – we were impressed by its full, punchy sound that's fairly expansive, and that doesn't crush when going loud.
