The 5 steps

How the home kit works

From the moment you order to the day your custom earplugs arrive — the whole process is simple, guided, and risk-free.

1

Order your kit

Choose your custom set and check out. Your impression kit ships out as soon as you order — and your spot in our build queue is reserved.

2

Kit arrives

A complete, room-temperature kit: silicone, syringe, oto-blocks, ear light, a sample impression and a prepaid label.

3

Make impressions

Follow the video and guide. About 10–15 minutes per person with a helper. Clean, mess-free silicone.

4

Mail it back

Repack everything, stick on the prepaid label, and drop it in the mail. Return postage is on us.

5

We craft & ship

Our craftsmen hand-build your set from your impressions and ship it to you — about 35–40 business days.

Watch & follow along

Making your impressions, step by step

Watch the full walkthrough, then follow the same steps below. Have a helper, take your time, and aim for deep, completely full impressions that match the sample in your box.

The full do-it-at-home impression walkthrough
Before you start: read every step through once and keep the kit at room temperature (about 70°F). The two-part silicone sets fast, so have your helper ready and your syringe within reach.
1

Fill out the form

Complete the invoice and check all the boxes so we build exactly the set you ordered.

2

Watch the full video

Understand the whole procedure first. Hold the sample impression from the box and note how deep and completely full the ear bowl is — that’s your target. There’s extra material in case you need a second try.

3

Get comfortable

Seat the person in a comfortable chair where a helper can easily reach both ears.

4

Check the depth

Gently place a Q-tip in the ear to gauge depth — you should feel more than an inch to the eardrum. The deeper down the canal, the better the seal we can make.

5

Inspect with the ear light

Look into the canal with the ear light. It must be clear of wax — we can’t capture an impression through a wax plug.

6

Seat the foam block

Place the foam oto-block to the second bend so it sits snug and fully fills the canal. The string should hang straight down — both equal — to the depth line on the ear light. Gentle, but deep.

7

Mix the silicone 7 seconds

Open the two-part silicone and mix vigorously until it’s a uniform pink throughout — only about 7 seconds. It sets quickly, so move fast.

8

Load the syringe

Roll the mixed silicone between your hands and load it into the syringe right away.

9

Fill the ear

Inject deep in the canal first, pulling out as you go and keeping the tip buried in the material so it packs into every nook. Fill the entire ear bowl — completely, like the sample.

10

Let it set

The silicone firms up in about 4–5 minutes. Stay still and relaxed while it cures.

11

Remove the impression

Once firm, start high on the ear, pull forward, and twist gently to release it.

12

Pack it up & mail it

Return everything to the box — ear light, syringe, completed form, and both impressions — apply the prepaid self-addressed label, and mail it back to us.

There’s no special skill involved. You don’t need to be a clinician — you just need a steady helper, a few quiet minutes, and the kit we send you. The silicone is a clean, putty-like material that mixes by hand and rinses off easily, so there’s no mess to worry about.

The foam block does the careful part for you: it stops the material at a safe depth and protects your eardrum, so all you have to do is fill the ear and wait. In four or five minutes the impression pops right out, and you’re done.

If anything feels uncertain, you can re-watch the video as many times as you like — and there’s extra material in the box, so a second attempt is built right in. When you’re finished, the prepaid box does the rest.

What customers say

Trusted by people who can’t compromise on their hearing

“I was nervous about doing it myself, but the video made it foolproof. My wife and I had both ears done in about fifteen minutes, and the fit is incredible.”

Jordan M.

“As a range instructor I’ve worn every plug out there. These are the first customs that actually seal and stay comfortable through a full day.”
M
Marcus T.

One kit, every kind of ear

Built for how you actually live

The same simple home process creates custom protection for every setting — tuned to the exact level of sound you need to block.

A few safety notes

  • Never push the foam block or silicone past comfort — stop right away if you feel any pain.
  • Always seat the foam oto-block first; it protects your eardrum and sets the correct depth.
  • The ear canal must be clear of wax. If it’s blocked, or if you have ear pain, tubes, or other ear conditions, see a professional before taking impressions.
  • Keep the kit at room temperature (about 70°F) for the best result, and have a helper take the impressions for you.
Good questions

Everything you might be wondering

How long does it actually take?
About 10–15 minutes per person once you’ve watched the video. The silicone sets in 4–5 minutes, so most of that time is simply getting set up and letting it cure.
Does it hurt?
No. The foam block and material only go in as far as is comfortable, and the foam block protects your eardrum. You should never feel pain — if you do, simply stop. Most people describe it as a mild fullness, like wearing an earplug.
What if I make a mistake?
It happens, and it’s no problem. Every kit includes extra material for a second attempt, you can re-watch the video as many times as you like, and our team is one call or email away if you want to talk it through first.
Is it safe to do at home?
Yes, when you follow the steps. The foam oto-block sets a safe depth and shields the eardrum, and the canal simply needs to be clear of wax. If you have ear pain, tubes, recent surgery, or any concern, check with a professional first — and you can always visit one of our providers instead.
Do I need a helper?
We strongly recommend it. Taking impressions is far easier and more accurate when a second person fills the ear and removes the impression for you. Most people grab a partner, family member, or friend.
When am I charged?
You pay when you place your order, and your impression kit ships out right away. That order covers your custom set, the kit, and prepaid return shipping — so once everything’s in your hands, there are no surprise charges. Ordering also reserves your place in our craftsmen’s queue, so your build begins the moment your impressions arrive.
How long until I get my earplugs?
Once we receive your impressions, our craftsmen typically hand-build and ship your custom set within about 35–40 business days.
What if they don’t fit?
If anything about the fit isn’t right, just reach out — we’ll work with you to adjust and perfect your set until it seals and feels exactly the way it should. We’re not done until it’s right.

Prefer to talk it through? We’re real people.

If you have any questions before you start — or want us to walk you through the impression process — reach out anytime. A real person will help you get it right.
