The 6 Best Waterproof Bluetooth Speakers - Summer 2021 Reviews

The best waterproof Bluetooth speaker with a floatable design that we've tested is the Ultimate Ears WONDERBOOM 2. This small speaker is rated IP67 for dust and water resistance and is advertised to float in water, though we don't currently test for this. Also, its lightweight design and small built-in carrying strap make it remarkably easy to take with you on the go.

Thanks to its 360-degree design, this speaker has incredible directivity, resulting in a wide and natural-sounding soundstage. It also has a somewhat neutral sound profile with a balanced mid-range, so lead instruments and vocals sound clear and present in the mix. That said, like most speakers its size, it struggles to reproduce the deep thump and rumble that's typically present in bass-heavy music like hip-hop and EDM. However, there's an 'Outdoor Mode' preset you can use to bump up the speaker's bass, though we didn't test this.

Unfortunately, it doesn't come with more comprehensive sound customization features like a graphic EQ to tweak the speaker's sound to your liking. It also doesn't support voice assistants, which may disappoint users who rely on them regularly. That said, while it can't get very loud, there are few compression artifacts present at max volume, so your audio sounds clean and clear during louder listening sessions.

The Sonos Move is the best versatile Bluetooth speaker we've tested. This very well-built speaker is rated IP56 for dust and water resistance, though we don't test for this. It's incredibly portable thanks to its built-in handle, so you can easily carry it around with you on the move. It also comes with Alexa and Google Assistant built-in and can understand your commands from far away and in noisy environments.

It has a neutral sound profile out-of-the-box, making it suitable for listening to a wide variety of audio content, and its balanced mid-range ensures vocals and lead instruments in your audio reproduce clearly. It can also produce quite a deep bass and comes with bass and treble adjustments you can use to customize its sound to better suit your preferences. Additionally, it comes with a handy room correction feature that adjusts the speaker's sound according to the acoustics of your room and recalibrates when the speaker moves. This speaker also offers very low Apple AirPlay latency, which may please some Apple users.

Unfortunately, it has to downmix stereo content to mono to play it, which doesn't sound as immersive. There's also some compression at max volume, so your audio may not sound clean and clear at louder volume settings. Still, its outstanding voice assistant capabilities, neutral sound profile, build quality, and portability make this versatile speaker one of the best Bluetooth speakers we've tested.

The best waterproof speaker in the budget category that we've tested is the Anker Soundcore Motion+. This speaker is rated IPX7 for water resistance, though we don't currently test for this. It's small, lightweight, and is battery-powered, so you can easily carry it around with you when you're on the go without needing to plug it into a power outlet.

It has a well-balanced mid-range that ensures vocals and lead instruments reproduce clearly. However, its underemphasized treble range can make higher-pitched vocals and instruments sound dark at times. Thankfully, its companion app features a graphic EQ and presets you can use to customize its sound to suit your preferences. It can also get decently loud and has an outstanding battery life, lasting over 15 hours from a single charge, though this depends on your usage habits.

Unfortunately, even with its BassUp feature turned on, it still struggles to reproduce a thumpy low-bass. It also doesn't have any voice assistants built-in, so it uses those available on your smartphone and doesn't do a great job of hearing you from far and in noisy environments. That said, if you're looking for a good waterproof speaker on a budget, it's still a good choice.
