Two women smiling together, one wearing C-Sound AI subtitle glasses

The voice is visible right in front of you.

The AI subtitle glasses display the other person's words in real-time on the lenses. No hearing aids needed, just as natural as regular glasses.

Problem

Have you ever experienced a moment like this?

  • An elderly man leaning in and cupping his ear, straining to catch the conversation during a family meal at home.

    I can't hear my family well.

    During a long-awaited family meal, listening to the stories of grandchildren… as we keep repeating 'Huh?', 'Could you say that again?', the conversation gradually dwindles.

    Problem 1

  • An elderly woman looking uncertain as a doctor speaks to her in a hospital consultation room.

    It's really tough at hospitals and government offices.

    Have you ever felt embarrassed when you couldn't understand what the doctor was saying in the consultation room, or when you couldn't follow the instructions from the staff at the bank or community center?

    Problem 2

  • An elderly woman resting her chin on her hand, hesitating while seated at a cafe table.

    Wearing a hearing aid feels a bit embarrassing.

    'Will I look old?', 'Will it be uncomfortable to wear?' There are reasons why people hesitate to use hearing aids even when they know they need help.

    Problem 3

In addition, hearing problems can cause many inconveniences.

Solution

With the C-Sound Subtitle Glasses, all these inconveniences are resolved.

The moment the other person speaks, subtitles appear right in the glasses' lenses. No need for earpieces or to draw attention like a hearing aid — conversation is visible with just these glasses.

“I can't hear my family well.”

I can't hear my family well.

Real-time subtitles for conversations with grandchildren during meals. The dialogue comes back to life.

Stories from those who experienced C-sound first.

I heard my grandson's words for the first time at the dinner table. It was so nice to be able to sit next to him and laugh together.
