Linus and the team take the plunge to figure out how to get tunes underwater, testing everything from custom hydroacoustic speakers built by Renzo at Synchrosound to bone-conduction headphones like the Shokz OpenSwim Pro and even a budget Monster S620 Bluetooth speaker. They hit the pool to see which setup actually pumps out clear audio during laps or underwater workouts.
Along the way they break down why high frequencies vanish beneath the surface, show off the guts of a pro-grade underwater speaker, and run side-by-side comparisons so you know which tech truly makes a splash. Whether you’re a casual swim-and-jam guy or hunting for the ultimate aquatic sound rig, they’ve got the tips and takes to keep you rocking under the waves.
