Super Soft silicone
Soft headphones, made for a full day under a helmet.
Every wired set is molded from impressions of your ears in our Super Soft silicone. There’s no hard shell pressing on your ear and no stem sticking out, so the helmet slides right over them and lifts off without moving them.

See the fit
In, helmet on, ride.
Soft silicone, molded to your ear canal. Line it up, press and turn, and it seats flush, so your helmet slides right over and lifts off without moving it. Insertion shown at real speed, helmet slowed down so you can see the fit.
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.
Compare the lineup
Five tiers. One soft silicone fit.
Every tier is molded to your ears in Super Soft silicone and built by hand in the USA. More drivers give each part of the music its own space.
Home impression kit included with every set. 30-day fit warranty.
How it works
What a transducer is, and why more of them means more sound.
A transducer is the tiny engine inside an earphone. It takes the electrical signal from your source and turns it into the sound you hear. In a custom in-ear, each transducer is a precision driver smaller than a grain of rice, built to move air with extraordinary accuracy.
One transducer has to reproduce everything on its own, from the lowest bass to the highest detail. It can, the way one voice can carry a whole song. But the extremes always give a little. Add transducers and you can split the work. A crossover sends the lows to a driver built for lows, the mids to one built for mids, and the highs to one built for highs. Each does a single job perfectly instead of every job adequately.
That is what you hear as you climb the ladder: bass with real weight, mids that stay honest, highs with air, and above all separation. Instead of every instrument fighting through one driver, each sits in its own space, so you can follow the bass line, the vocal, and the cymbal at once. More drivers also mean more headroom, so loud, busy passages stay clean instead of breaking up.
Here is the part most brands skip. Drivers only perform if the seal is perfect, and no universal tip ever seals an ear it was not made for. We mold every shell to an impression of your exact ear in our own soft silicone, so the fit is complete, the isolation is total, and the drivers deliver everything they are capable of. The sound you paid for is the sound you actually get.

The detail
Wind at seventy drowns out everything: your music, your GPS, the rider beside you. So you turn it up, and now you have wind and a headache, and your ears are worse off than when you started.
These fix it at the source. A single-transducer earphone molded to each ear seals the wind out, so your audio comes through clean and full at any speed, at a volume that is finally kind to your ears. One full-range driver, a custom fit that will not budge under a helmet, comfort that lasts the longest rides.
Built for the people who actually live on two wheels.
Hand-built in the USA, one pair at a time, and backed by our 30-day fit warranty.
