■ Background of the Launch

The Company has been addressing the issue of "hearing difficulty" for over 10 years. The home-use "MIRAI SPEAKER®" series, equipped with the proprietary "Curved Sound®" technology, has delivered a cumulative total of 400,000 units*3 as speakers that improve the difficulty of hearing TV dialogue, and we have received comments from many customers such as, "I can now enjoy watching TV with my family."

However, by listening to our customers' voices, we realized that hearing issues are not limited to just in front of the TV.

Approximately 13 million people*4 in Japan have hearing difficulties. Scenes where it is "hard to hear" are everywhere in daily life, such as conversations with family, lunch with friends, and meetings and discussions at work.

You couldn't catch what was said, but you nod anyway.

You feel sorry for asking again, so you let the conversation pass.

There are not a few people who gradually distance themselves from conversations in this way.

We found that behind the tendency to leave hearing difficulties unaddressed, many people feel resistance to wearing hearing support tools in their ears. There are "three barriers" to this.*5

[Barrier of Wearing Sensation] The style that goes inside the ear causes a feeling of pressure, making it difficult to go about daily life.

[Barrier of Design] The appearance makes you feel your age, and you don't feel like wearing it daily.

[Barrier of Price] There is an image of being expensive, making it hard to casually purchase.

The world's first ear cuff-type sound collector with hearing adjustment function, "MIRAI SPEAKER Ear," is a "new option" born to overcome these barriers one by one.

From the spread of support so far, we feel that empathy for "a wearing sensation that doesn't block the ear," "a design that is easy to incorporate into daily life," and "a function that can be adjusted to suit your hearing" is steadily spreading. In addition to the need to enjoy daily conversations more for personal use, the need to give it as a gift to family members also boosted support, leading to the total support amount exceeding 400 million yen. Furthermore, achieving the all-time No.1 ranking in the entire earphone category on GREEN FUNDING is proof that the sound collector has received high support, and we also take it as a result showing that issues related to "hearing" are a familiar and pressing theme in society.

Many people also visited the exhibitions and trial sessions held in Tokyo, Nagoya, Osaka, and Fukuoka. While actually trying the product, they highly evaluated the comfortable wearing sensation that doesn't block the ear and the ability to adjust the sound to suit each individual using the hearing adjustment function. In addition, the remote microphone function via the charging case, ease of volume adjustment and operation were also well-received as features that are easy to incorporate into daily life. In the comments of support, we also received messages saying that through the trial sessions, their understanding of the product deepened, leading to support with peace of mind, and all staff members are very happy about this.

■ "Hearing Adjustment Function" is a Big Hit! Voices from the Experience (Excerpts)

[I thought, "I can use this" the moment I adjusted the hearing]

It was my first time with both hearing aids and sound collectors, and I was resistant to the type that goes inside the ear, so I came to try a type that doesn't go in the ear. At first, the high-pitched sounds were annoying, but by suppressing the high-pitched sounds with the hearing adjustment function, it became very easy to hear, including my own voice. Even when comparing the difference by putting it on and taking it off, it was much easier to hear with it on, and I was also attracted to the fact that I can continue to adjust it with the app in the future.

[I felt it would reduce the number of times I have to ask people to repeat themselves at work]

Since around last year, my health checkup pointed out that my ability to hear low-pitched sounds was deteriorating, and I felt that the number of times I had to ask people to repeat themselves at work was increasing. Especially in meetings with clients, I can't keep asking them to repeat themselves, so I searched for a sound collector that could compensate, even if it wasn't a hearing aid, and found this product. At first, there was a feeling unique to sound collectors that "all sounds become louder," and my own voice also felt noisy, but when I adjusted it to my ears using the hearing adjustment function, my impression changed completely. The noisy sounds settled down, and it became much easier to hear. I realized the importance of being able to adjust.

[I was surprised that it suppresses high-pitched sounds and only delivers the sounds that are hard to hear]

My wife has mild hearing loss, and I have hearing loss only in my left ear, so when someone speaks to me from the left side, I can barely hear mid-to-low and low-pitched sounds. We were worried about the cost of both of us suddenly buying hearing aids, and we were wondering what to do when we learned about this product. When I tried it, I was very impressed that the sounds I had difficulty hearing became surprisingly audible thanks to the hearing adjustment function. Moreover, even though the volume was turned up quite high, the high-pitched sounds were well suppressed, and I was also surprised that my ears didn't get tired easily.

[It changed from "everything is noisy" to "I can hear the necessary sounds"]

Perhaps due to aging, it became difficult to hear my daughter's voice, and my health checkup also pointed out a decline in hearing around 4,000 Hz. I thought I should do something before I seriously had trouble communicating, and although it was too early for hearing aids, I decided to first try a sound collector and came to the trial session. At first...
