Fully h ome-compostable and free from plastics. GOB's Quad is a truly compostable earplug made entirely from lab-grown mycelium, offering comfort, clarity, and peace of mind without harming the planet. With 20dB of consistent, balanced sound reduction, it softens disruptive noise across all frequencies—whether in hotel rooms, flights, gyms, or at live shows—without muffling important sounds. Quad’s mycelium foam shapes to the ear like memory foam, ensuring a secure, pain-free fit that stays in place. Unlike synthetic plugs, Quad breaks down completely after use, returning nutrients to the soil with zero microplastics or toxins. Quad delivers chemical-free, body-safe hearing protection that respects both personal health and environmental impact. Show more
