Elliot and the greater Crystal Guardian team are all-stars. These folks are both excellent at their work and super solid human beings. As legacy brands like Etymotic fall into the abyss of enshittification, CG only continues to rise. 5 stars, bang-up work, no notes. Keep up the awesome!

This is such a great, important service! Elliot took my ear canal impressions at a popup event, and in the process, he flagged a potential health issue that prompted me to see an ENT, which turned out to be really helpful. Thank you, Elliot! And I love my Crystal Guardian earplugs. Keep up the good work.

Five stars for Crystal Guardian! The whole experience of getting these was so simple, and the team provided amazing service every step of the way. I am in love with my custom earplugs—it’s so cool having a pair that is 100% unique to me. Best earplugs ever!

Prompt, easy, quick - wish i'd done this long ago. Elliot is super professional and walked us through the whole process, it took mere minutes, and i didn't expect to go for the glitter options until i saw them in person and realized i had no other choice. Would recommend very highly.

Elliot was incredibly helpful, knowledgeable, and an all around GREAT guy!!!

Exceptional! The custom-made silicone ear plugs are so comfortable. Most of all they help me so much. Thank you Elliot they came out so pretty! My appointment was so quick and easy. Thank you again!

A big shout out to Elliot, who kept me updated on the status of my filter order ahead of an upcoming festival. I've had my CG earplugs for over a year now, and they have been absolutely wonderful — super comfortable, incredible sound fidelity, cute, and easy to find when they fall on the dance floor (the green color is BRIGHT).

I recently wanted to upgrade to stronger filters for long days of loud festival music. Since I placed the order a little close to the festival date, I was cutting it tight, but Elliot went above and beyond to make sure everything arrived in time to keep my eardrums safe. Many thanks to him!

If you're on the fence about these earplugs, take the plunge — they are worth every penny.

Working with Elliott was an absolute pleasure! He cares so much about the quality of his earplugs and making sure customers get what they need out of it. I would absolutely recommend him.

I went to the Brooklyn studio to have these molded and received my final product in a few weeks thereafter. I wish I'd gotten them sooner. I purchased with the intent of using these during concert and festival attendance but started using them daily in my gym classes because the coach's music is always blasting. I can easily hear the coach's cues and the music through the ear plugs without getting a headache like I did before. The plugs are so comfortable and easy to use. 10/10 would buy again!
