SUMMARY
earHD 90 is a passive hearing device that increases detail and reduces distracting ambient noise. Simply look and listen.
• Improved speech intelligibility (how well we hear human voice)
• Increased signal to noise ratio (reduced background noise)
• Enhanced frequency response (higher levels of detail)

FROM THE INVENTOR
About 3 years ago I started looking more closely at our ears - I wanted to understand how the human ear worked and what I discovered was that there is a significant problem to do with how we hear the quality of sound.
Most of the sound we hear is distorted. We can’t naturally hear high definition sound from the front. It’s simply not possible due to the shape of our ears. Our ears are very good at receiving quality sound from the sides and from devices like headphones as this sound travels straight into our ears bypassing the pinna.
We’ve gone through over 50 prototypes to get it right.
Simply put: Sound that I’m looking at I want to hear in high definition and sound that’s coming from elsewhere I want to blur out and reduce.

EARHD 90 TECHNOLOGY
earHD uses a 60 - 90 degree reception from left to right to focus sound coming into our ears. Simply put: where we look is where we want to hear in high definition, sound coming from elsewhere is blurred out and reduced.
In order to receive higher levels of detail from the front, earHD 90 acts like a satellite dish and diffraction shield combined.
It uses a precise acoustic lens that focuses sound uniformly into one central location. This focused sound is then accurately reflected straight into our ears, revealing higher definition sound from where you are facing. The diffraction shield aspect blocks unwanted higher frequencies from outside the desired 60 - 90 degree reception window that would have otherwise entered our ears at a much higher level which normally damages harmonic reception.
The ISVR (Institute of Sound and Vibration Research) at the University of Southampton has conducted completely independent tests on earHD 90 to verify our claims. You can download the full report below.
