Ever wondered how to rock out beneath the surface? Linus and Renzo go deep into underwater audio, testing custom hydroacoustic speakers, SHOKZ OpenSwim Pro bone-conduction headphones and a budget Monster S620 Bluetooth speaker. They explain how water kills high frequencies and why bone conduction can be a game-changer, then dive into pool demos to see which setup really works for laps and workouts.
Along the way, Renzo shows off his DIY underwater speaker designs from Synchrosound, Linus runs side-by-side comparisons, and they share pro tips for anyone wanting tunes while they swim.
