Can You Listen to Music Underwater?

Linus and team dive into the pool to test everything from Renzo’s custom hydroacoustic speakers (made by Synchrosound) to popular bone-conduction headphones (SHOKZ OpenSwim Pro) and even a budget waterproof Bluetooth speaker (Monster S620). Along the way they explain why sound loses high frequencies underwater, how bone conduction really works, and share pro tips for an uninterrupted aquatic playlist.

Spoiler alert: Renzo’s purpose-built underwater speakers deliver the richest, clearest sound for lap swims, bone-conduction headphones are a convenient middle ground, and your average waterproof Bluetooth speaker ends up feeling muffled once you’re submerged.
