Custom Headphones & IEMs
Custom In Ear Headphones
Custom-molded single-transducer earphones for ears that off-the-shelf buds never fit. One full-range driver, a close seal, and sound that finally lands.
“The fit and comfort is unmatched and the build quality is impressive. But the sound, now that’s where the magic lies.”
Alex F., verified review, April 2025
Home impression kit included
You make the impressions at home. We do the rest.
The real process, shot by shot, at real speed.
No audiologist visit. An audiologist typically charges $80 to $100 for impressions. Your kit is included with your order, and if an impression needs a redo, we send another kit at no charge.
- Made in the USA. Molded, hand-finished and inspected in the USA.
- Built for one pair of ears, yours. Nothing here is off the shelf.
Shell: Super Soft silicone, included. Home impression kit included.
Super Soft silicone
Soft headphones you can wear for hours.
Every wired set is molded from impressions of your ears in our Super Soft, platinum-cure silicone, not hard acrylic. Squeeze it and it gives, then springs back to the shape of your ear, so it stays comfortable through a long set, a long ride or a long shift.

What is inside
Drivers, explained simply.
Every Big Ear headphone is built with Knowles transducers. A transducer, or driver, is the tiny speaker inside each earpiece that turns the signal into sound. One driver covers the whole range on its own. Add drivers and a crossover splits the range, so each one covers a narrower part of it.
5 and 8 drivers: the same range, shared by more drivers.
| Model | Drivers | What it does |
|---|---|---|
| The Daily | 1 | One full-range driver. Clean, natural sound. The best place to start. |
| The Pro | 2 | Two drivers split the work, so the lows stay full while the detail opens up. |
| The Studio | 3 | Dedicated lows, mids and highs. Clear separation for serious listening and the stage. |
| The Master | 5 | Five drivers for more headroom and finer detail across the whole range. |
| The Stage Master | 8 | Our top build. Eight drivers for the most detail we make. |

How it works
Four simple steps, start to finish
Every set is made from impressions of your own ears. You take them at home with the kit we send you. Watch the process →
Step 1: Order
Choose your options and check out. Your home impression kit is included.
Step 2: Receive your kit
It arrives 3 to 5 business days after we receive your order. Watch your email for the tracking number.
Step 3: Make your impressions
About 15 to 20 minutes at home, with a video that walks you through every step. You can do it yourself; a second person makes it easier.
Step 4: Send them back
Pack them in the same box and use the prepaid return label. We start building the day they arrive.
Then we hand-build your set in 40 business days from the day your impressions reach our lab and ship it to your door, with a 30-day fit warranty. If the fit is off, we adjust or remake it.
Watch the kit, step by stepQuestions about the kit
What if my impression doesn’t come out right?
We check every impression before we build. If one needs to be redone, we send you another kit at no charge. The kit also has extra material in case you want a second try.
Do I need someone to help me?
No. You can take your impressions yourself by following the video. A second person makes it easier, because they can see into your ear, but you don’t need one.
When will my order arrive?
Your kit arrives 3 to 5 business days after we receive your order. Once your impressions reach our lab, we hand-build your set in 40 business days and ship it to your door.
Already have impressions? If we made your last pair, choose “Big Ear already has my impressions” at checkout. From an audiologist? Mail them to Big Ear Inc, 101 Durden Park Row, Blythewood, SC 29016.
See the fit
In by hand, in seconds.
Soft silicone, molded to your ear canal. Line it up, press and turn, and it seats flush. Shown at real speed.
Built to be kept
One set. Years of listening.
Universal earbuds wear out their tips, lose their seal and get replaced. A Big Ear set is molded to your ears, built to last 3 to 5 years, and fully repairable when something wears out, so a worn part means a repair, not a new pair.
01
Fits like nothing off a shelf
Molded from impressions of your own ears, so the seal holds, the sound stays full and they stay comfortable for hours.
02
Repair, don't replace
When something wears out, we fix it. Your set keeps going instead of ending up in a drawer.
03
Fewer earbuds in the trash
No new pair every year or two. One set, looked after, for years.
Hand-built in the USA
Made for your ears alone.
Not assembled overseas, not drop-shipped, not rushed. One pair at a time, for one set of ears at a time. We are proud of that, and we think you can hear the difference.
The problem with universal earbuds
Universal earbuds and IEMs were never shaped to your ears.
Foam and silicone tips are built for an average ear, so they rock loose, leak the low end, and ache after an hour. A shell molded to you fixes all of it at once.
The Big Ear difference
Molded to your ears. Tuned to your sound.
We take a separate impression of each ear and build a custom shell around your drivers, from a single transducer up to eight. A sealed custom fit gives you the full low end, real isolation, and all-day comfort a universal tip cannot. You pick the driver count for the detail and separation you want.
More drivers means more separation between instruments. Start where you are, step up when you are ready.
What customers say
Worth getting right.
“The fit and comfort is unmatched and the build quality is impressive. But the sound, now that's where the magic lies.”
Made to order, made to fit
Hear everything you have been missing.
Every set is molded to your ears and built by hand in the USA. Take a quick impression at home with the included kit, and we build your monitors around it. Backed by our 30-day fit warranty.
The detail
Off-the-shelf earbuds are built for an ear that does not exist. If yours are hard to fit, or one side never quite seals, you already know the drill: they work loose, the bass leaks out, and the music never really lands.
These are built the other way around. We take an impression of each ear and mold a single-transducer earphone to the exact shape of your canal. One full-range driver, a complete seal, and a fit that vanishes the second it is in. Clean, natural sound. Real isolation from the room. Comfort that holds through a full flight, shift, or ride.
It is the easiest way into true custom audio, and the best place to start.
Hand-built in the USA, one pair at a time, and backed by our 30-day fit warranty.
