We dive into testing underwater audio, from custom hydroacoustic speakers by local expert Renzo to bone-conduction headphones like the Shokz OpenSwim Pro and budget waterproof Bluetooth speakers (Monster S620). We break down why high frequencies vanish underwater, how bone conduction sneaks around that, and put each gadget to the pool-lap test to see which really pumps out tunes during swim workouts.
Along the way you’ll catch DIY insights on building pro-grade underwater speakers, real-world hearing demos, and handy tech tips for getting your favorite jams underwater. Plus, there’s a community forum link for extra chatter if you want to geek out on underwater sound science.
