So comfortable, you’ll forget they’re in there.

GOB partners with nature to evolve your everyday life into the regenerative future. We are reinventing wearable wellness products that are engineered with biology, designed with a long-term vision. As the world’s first earplug with a conscience, our product is made from lab-grown mycelium.

Our single-use plugs have been engineered by nature to tune your experiences to the right volume, without any harmful materials or chemicals. They are completely home compostable and will feed the ground wherever they end up.

Earplugs might not sound like a big environmental problem, but when you discover that the world manufactures 40 billion of them a year (If laid end-to-end, 40 billion earplugs would stretch over 2.4 million miles, which is enough to wrap around the Earth nearly 100 times.

To this day, single-use earplugs are still made of petroleum-based materials, mostly PVC, which are endocrine disrupting, cancer-causing, and cause environmental harm. We saw an opportunity to fix this problem to not only make a less harmful product, but one that actually regenerates the health of the planet with every use.
