Background of the Launch

Our company has been addressing the challenge of "hearing difficulties" for over 10 years. Our home-use "MIRAI SPEAKER®" series, equipped with our unique "Curved Sound®" technology, has delivered a cumulative total of 400,000 units*2 as speakers that improve the clarity of TV speech, receiving many comments from customers such as "Now my family and I can enjoy watching TV together."

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

Approximately 13 million people*3 in Japan face hearing challenges. Situations where "it's hard to hear" are common in daily life, such as conversations with family, lunches with friends, and meetings at work.

・ I couldn't hear, but I just nodded vaguely.

・ I felt bad asking again, so I just let the conversation go.

As a result, many people gradually withdraw from conversations.

Behind leaving hearing difficulties unaddressed, it became clear that many people feel resistance to hearing support tools worn on the ear. There are "three barriers" to this. *4

【Barrier of Wearing Comfort】 In-ear styles feel oppressive and make daily life difficult.

【Barrier of Design】 The appearance makes one feel their age, and they don't want to wear it daily.

【Barrier of Price】 It has an expensive image and is not easily affordable.

"MIRAI SPEAKER Ear" was born to overcome these barriers one by one, offering a "new choice."

By overcoming these "three barriers," both the need to enjoy daily conversations more for personal use and the need to give it as a gift to family*5 have expanded, which we believe is one of the major factors behind this 100 million yen breakthrough.

Customer Voices (Excerpts)

【More enjoyable conversations with family】

I gave a Mirai Speaker to my father, and he uses it a lot, but this time it's for myself. With this, conversations with family and grandchildren will be more lively. I found the easy volume adjustment with the charging case very convenient. (Male, 60s)

【No app needed. Simple, so I want to give it to my parents】

For my mother who lives far away. A previous product from another company I tried was large, and I was concerned about its operation and sound pickup, so I passed on it. The appeal of this one is that it can be used simply without an app. The wearing comfort is good, and I think my elderly mother will be able to use Mirai Speaker Ear Lite without confusion. (Female, 50s)

【Easy to try casually】

Recently, I've been feeling a bit hard of hearing and tried it. I thought it was good that voices that sounded muffled before now sound clearer. It was also appealing that it's easy to use just by wearing it, and the operation is simple. (Female, 60s)

【Easy to wear even with glasses and masks】

I haven't used hearing aids or sound amplifiers before, but I've been thinking about it and came to try it. When I put it on, it was good that it didn't interfere with masks or glasses and was easy to wear. I felt it would be easy to incorporate into daily life. (Male, 70s)
