A sensory delight

5.0

These are awesome - softest earplugs ever - the ONLY ones I’ve ever tried that don’t hurt my ears in the morning and also don’t hurt after using them multiple nights in a row (not the same ones of course!). No they aren’t noise cancelling but they don’t NEED to be in order to be effective. They remove the right kind of sound, if that makes sense. I’m in love.

The product is awesome! They are the most comfortable non-custom earplug I've ever worn, by far. They are easier to put in. They are not bad for the planet. They are hypoallergenic. Just love them!

GOBs are a game changer plus something that is finally comfortable.

gobs are great! I bought them at the Fred Again concert in NYC and they were a total lifesaver. The high fidelity protection is incredible. They perform better than my ~$100 ear protection.

Place the earplug gently at the entrance of your ear canal. Do not pinch or roll.

Place a finger against the flat outer end and press forward until the earplug sits comfortably. Leave enough exposed to safely remove it after use.

gobs are made from 100% mycelium, the root-like network of fungi that grows naturally beneath the soil. It’s a renewable biomaterial that’s non-toxic, hypoallergenic, and completely natural.

After use, place your gobs in your home compost bin. They’re made from 100% mycelium, a bio-based material that naturally breaks down and returns nutrients to the soil.

Yes. gobs are designed for all-night comfort, with natural foam that adapts to your anatomy.

They’re single-use, so start with a fresh pair each night. Follow the fitting instructions above and leave enough of each earplug exposed to remove it safely.

Use one fresh pair each time you wear gobs. Core contains 12 pairs and Sustain contains 30 pairs.

If you wear them every night, that’s 12 nights from Core or 30 nights from Sustain. If you use them less often, your pack will last longer.
