The Bose QuietComfort Ultra Headphones (2nd Gen) are obsessively engineered with our best noise cancellation and spatialized audio for immersive listening. They perform especially well against steady, low‑frequency sounds like engines. That means they can significantly reduce the rumble from boat motors and 18‑wheeler trucks.
Sorry, there was a problem.
Please try again later.They likely would block a large chunk of both. I'd reconsider for boat usage though. I've used these on an airplane, and turbulence/bumps/wind noise causes audible popping and cracking that makes them nearly unusable.
