Earplugs designed to be ideal for those sensitive to sound and easily affected by weather.
Made by incorporating customer feedback to create a product that can make you smile even more.

Evolved from the previous generation to the next-generation device with an even more conversation-friendly setting.
Although it was a popular previous model, it was renewed as a next-generation device based on valuable customer feedback received at that time.
A major change is the successful elimination of noise without using an acoustic filter, making it easier for air to pass through and providing an unprecedented sense of openness.
Additionally, the on/off setting has been reviewed, making conversation easier during open mode and increasing practicality.
Please try the next-generation earplugs.

Born from a revolutionary technology that eliminates noise by resonating and canceling out sounds without using an acoustic filter, allowing for a sense of air.

For those troubled by sound

For those with sound sensitivity
Designed to efficiently remove high-pitched sounds, deep bass, and sudden loud noises without completely blocking out sound.
Therefore, necessary sounds in daily life can be heard, allowing you to wear them with peace of mind and live your life continuously.
Also, since it is now filterless and designed to allow air to pass through, it reduces stuffiness and pressure differences caused by continuous wear, creating a comfortable space.


For those easily affected by weather changes
A new design that gradually adjusts to pressure changes without sudden shifts, suitable for days with bad weather or those sensitive to pressure fluctuations.
Furthermore, by operating a switch, you can quickly release pressure and enjoy a relaxed environment at your preferred timing.


For those who want to have conversations
Traditional earplugs completely block out sound, making it difficult to hear necessary conversation sounds, but thanks to the space resonator, this product achieves a filterless design that cancels noise while allowing necessary voices to be heard, so you can enjoy conversations anytime.

・Major update. Redesigned ear tips for those with small ears, changed to a noiseless plastic case, and added new colors.
Designed for 'sound sensitivity / weather pain' users who react sensitively to sound or experience headaches due to weather pressure differences.
Conventional noise-canceling earplugs with sponge filters could block necessary sounds and make pressure adjustment difficult, causing discomfort.
This earplug adopts a newly developed space resonator (resonator) and successfully eliminates the filter.
It blocks only unpleasant sounds, allows necessary sounds and air to pass through, making it very comfortable.

For those suffering from weather pain, unlike sponge filter earplugs that block sound, this design allows air to flow, making pressure adjustments between outside and inside easier and creating a relaxed environment.
Additionally, by operating a switch, you can release internal pressure while wearing, making it easier to create your preferred environment.

Because it is a non-blocking earplug, it allows necessary air to enter without sealing the ear canal, resulting in a less occlusive and very open feeling.
Even those who dislike the feeling of occlusion or muffled sound with traditional earplugs will find value in using this product.

For those worried about whether the ear size will fit,
The size and depth of Japanese ear canals vary greatly.

We want many people to be satisfied, so we offer a total of 6 types of ear tips to fit a wide range of users.
With just a switch on the main unit, you can change the acoustic environment.
You can switch between open mode for conversation and closed mode for work or study, depending on the environment.

You can operate with a single touch without changing multiple earplugs.
