Diving is more than depth and equipment. It’s about being in tune with the ocean. For divers who choose to use earplugs, a properly vented design is essential to avoid creating a sealed air space, allowing for a connected diving experience while protecting your ears, without the risk associated with using solid earplugs.
SurfEars protect your ears while still allowing sound and pressure to move naturally. This helps reduce discomfort from cold water and pressure changes while preserving sound transmission and situational awareness.
At the core of SurfEars is our patented hydrophobic acoustic mesh, designed to allow natural pressure equalization while protecting the ear canal. This makes SurfEars ideal for divers who want reliable ear protection without affecting their ability to equalize.
How SurfEars Work During Diving
Surface protection – The hydrophobic mesh blocks water at the surface while allowing sound and pressure to pass.
Water trap design – At depth, a small amount of water may pass through the mesh and enter the internal channel. As pressure increases, a limited amount may also enter the outer ear canal, compressing the trapped air and helping the pressure outside the eardrum move toward ambient pressure. A compressed air pocket may remain closest to the eardrum.
Self-draining system – During ascent, the trapped air expands and can help push water back out through the mesh. This may explain why many users report little or no retained water after a dive.
Natural equalization – The large distributed mesh area allows pressure to be transferred through the system. At depth, controlled water entry and compression of the trapped air are believed to help the pressure in the external ear canal follow ambient pressure. Divers must still use their normal active middle-ear equalization technique.
SurfEars 4.0 builds on our patented hydrophobic acoustic mesh with improved durability and a new wingless option for comfort under diving hoods.
Made partly from recycled ocean plastics and repurposed, medical grade silicone, it delivers reliable performance in demanding diving conditions.
SurfEars was created in response to a very real and common problem.
Prolonged exposure to cold water and wind can lead to ear damage, infections, and hearing issues over time for people who spend a lot of time in the water.
Our founder, Christian Dittrich, a cold water surfer and former competitive swimmer, experienced this firsthand.
At age 30, he developed a severe case of surfer’s ear after years in cold conditions. During a surf trip to Morocco, recurring ear infections made it clear that existing ear protection did not work well enough.
Together with a team of engineers, he set out to develop a better solution. One that would keep water out without isolating the user from their surroundings.
For divers, exposure to cold or polluted water presents similar risks. Wearing diving earplugs is not only about comfort. It is about reducing the risk of infections, protecting your ears over time, and staying safe in the water.
With SurfEars, you limit water entry while remaining aware of your surroundings. The hydrophobic acoustic mesh is designed to preserve sound transmission and situational awareness.
