"As long as you have open ears, they will be even more open."

Stephen Fry Actor, author, broadcaster and comedian

"When I’m at the piano It feels like all I hear is music. Total immersion. Which is excellent. Pure, undiluted concentration. Really impressive.”

James Rhodes Classical pianist

Upgrade your ears


After two successful crowdfunding campaigns, earHD 90 is now available on our website. Choose from three models that use patent pending technology to open your ears.

earHD 90 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.

Acetal


earHD 90 comes in a lightweight black acetal and polished for a high gloss finish.

Three sizes of silicone tips allows you to get the perfect fit and angle to focus your sound.

Our ears are wonderful things


As our ears are on the side of our head they are especially great at determining where sounds are coming from. The outside of our ear (the Pinna) has evolved to help us do this by distorting sound based on which direction the sound is coming from. This means that what we gain in placement of sound we lose in definition and sound quality. High frequencies in particular lose their sparkle, definition and sibilance when sound emanates from in front of us. 

Our ears are very good at receiving high quality sound from the sides and from devices like headphones as this sound travels straight into our ears bypassing the Pinna.

However, when we put our ears into venues and different shaped acoustic spaces, suddenly we are hearing sound from in front of us. That plays havoc when trying to hear high definition sound because of the interfering reflections coming from all other angles.

Simply look and listen

We believe that what we’ve created with earHD 90 is a new exciting tool to open your ears and hear the world in HD. Rediscover sound and hear subtleties and nuances that you have been previously unaware of with your new upgraded ears.

Independent Testing

The Institute of Sound and Vibration Research (ISVR) conducted independent testing on earHD 90 to see what affects it has on our ears.

The hashed area shows a large boost in energy which makes focusing on specific sounds in front of us difficult. earHD 90 has three benefits:

• Improved speech intelligibility (how well we hear human voice)
• Increased signal to noise ratio (reduced background noise)
• Enhanced frequency response (higher levels of detail)

The Reveals

Without earHD 90


Distorted and reflected noise as well as sounds from the side (red and green) have an easier path to the ear canal which interferes with sound coming from the front (blue).

With earHD 90


We want to upgrade your ears to let them hear more detail and higher quality sound without just increasing the volume. With earHD 90 you can focus on sounds from the front and reduce distracting noises from the side.

How?


earHD 90 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.
