Product description

Key Benefits

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.

Why GOB is Healf

GOB was born with a mission to transform everyday wellness through nature-led innovation and conscious design. Founded on the belief that small choices create meaningful change, the brand reimagined the humble earplug using lab-grown mycelium instead of petroleum-based materials. Their compostable earplugs tune sound without chemicals or plastics, breaking away from the billions of disposable plugs that harm people and the planet each year. By combining biology, engineering, and long-term environmental thinking, GOB offers a regenerative alternative crafted for comfort and responsibility – helping you protect your ears while caring for the world around you.

With our Healf Curation Process, we do the work for you. Shop with confidence knowing that every item has been tried, tested, and curated for you.
