The First Size-Adjustable Open Ear Headset

"Where Is the Sound Coming From?"
Bone conduction sends audio directly to your inner ear through cheekbones.
Sentien's perfect-fit adjustment ensures precise transducer positioning - the key to superior sound. This optimal contact delivers audio quality beyond standard bone conduction. You don't just hear your music, you feel it.
"The sound quality is better than expected for bone conduction. It was totally worth the wait."
— Romaric M.

Adjustable = You Forget It's There
You'll feel the difference the first time you slide Sentien Audio into place.
Unlike fixed-size headsets, our titanium band adjusts to perfectly match your unique head shape. This is essential for bone conduction to transmit sound waves. Sentien Audio transforms both sound quality and comfort level.
“The adjustable band is a game-changer. I was able to wear them with a beanie and hat without any discomfort.”
— Michael C.

Designed So You Forget It's There
The ergonomic design will make it seem like the headset vanished. The result? A headset that feels so natural you'll forget it's there.
"After several hours of use, I didn't even realize I had something on my head."
— Martin S.

Born from Passion, Perfected Through Perseverance
A small team of designers and engineers in Europe dedicated to creating the most comfortable ambient headset. Giving you sixth sense - your digital inner voice. So you can stay relevant in the age of robots and AI.
Research, prototypes, crowdfunding, pandemic, supply chains, mistakes, compromises, alive, dead, alive, dead, alive... Born and reborn through hope, sweat and tears.
We didn't give up, and our product is now shipping to enthusiastic customers worldwide.
"In a sense this is one of the most amazing Kickstarter projects I've been involved in. It embodies what Kickstarter is about — funding a vision with all of the associated risks of a new venture.
I am in awe that you have persevered through to the end of the project. I think many would have folded quite awhile ago."
- Josh S.
"Kudos for pushing through with this project. It's been difficult and most campaigns in similar situations pull out. Well done. The headset works great."
- Dolf S.
