Orfeo SoundWorks

AI companies launched AI earbuds recently, attempting to preoccupy
the voice-driven AI platform available not only indoor but also outdoor in order to
grow their market sizes. But, their products do not have reliable voice recognition
since the surrounding noise is not fully canceled out. For improving a listening and
phone call experience, Orfeo SoundWorks developed Inner-mic technology. We placed a mic
inside of earbuds to pick up the voice traveled through the Eustachian tube and block off
the surrounding noise physically.

Our Vision

The importance of audio quality is slightly more essential than visual quality.
Orfeo SoundWorks wants to provide the best audio quality and communication experience.

Who We Are

We are a group of engineers who participated in many government projects regarding sound quality tests.
We specialize in developing audio solutions and testing audio accessories.
With our knowledge and skills, the group of experts started the company called Orfeo SoundWorks and developed
inner-mic earbuds that can completely block off the ambient noises for improving your listening experiences .
