Can you really rock out while doing laps? Linus and the crew dive into the world of underwater audio, testing everything from Renzo’s custom hydro-speakers at Synchrosound to bone-conduction Shokz OpenSwim Pros and a budget Monster S620 Bluetooth speaker. Along the way they explain why high frequencies vanish underwater, how bone conduction lets you “hear” music without drowning your eardrums, and put each setup through real-world swim and workout tests to find the best splash-proof sound.
Sprinkled with quick tech tips, product recs, and sponsor shout-outs (hello, EcoFlow and Micro Center), this deep-dive video breaks down everything from speaker design to final pool-side verdict in bite-sized, entertaining chapters.
