We loved using the Swimmer in so many places: having a shower, while cooking in the kitchen, in the bicycle cycling in the park, swimming pool, on the beach... no problem! This wireless speaker is so light and small you can take anywhere - even water! It is not simply ‘water resistant’, the BOOM Swimmer is 1 meter deep waterproof (IPX7 using its tail) but Bluetooth connection will probably drop... physics. I consider the Swimmer the safest "Bluetooth Shower Speaker" available.

I frequently use headphones/earbuds (when I am on a public space) or play loud music on the Home Theater (coming from the Mac’s iTunes library, using an AirPort express/AirPlay). But my wife watches a lot of YouTube videos from her iPhone while she cooks - and the sheer volume of the iPhone speaker can’t compete with other kitchen sounds. In the kitchen it makes a lot of sense: small, no wires, wet hands or water accidents are not a problem. And listening to music in the shower is an experience apart (don’t say “duh, yeah!” - I did it very few times, ha ha, so it is still a big deal). This is not a sponsored review. I bought the speaker and did the review on my own. Bottom line: I like it a lot. Recently I listened to several Bluetooth Speakers in stores - and of course you can find lots of options with deeper and louder sound, but they are much heavier, bigger and cost a LOT more. The Boom Swimmer has nothing to do with “sound-systems”/stereo/living-room… But it is perfect for what I’ve shown in the video. ———— Featured songs provided by YouTube Audio Library, free music; listed by appearance order in the video: “Opening Night”, Jason Farnham “Blues Blast”, John Deley “Play Song”, John Deley and the 41 Players “Dixie Outlandish”, John Deley and the 41 Players “Non Piu Andrai”, Ron Meixsell “Horses to Water”, Topher Mohr and Alex Elena “Led Foot”, Ethan Meixsell “Loophole Fragment”, Silent Partner “World Map”, Jason Farnham ———— Written, Performed and Produced by Everson Siqueira Voice recorded with the Blue Yeti USB Condenser Microphone on Cardioid Pattern.
