Is it sometimes difficult to hear even with the volume turned up to maximum?

Even with the volume turned up to maximum, it may be difficult to hear.

By setting it to the maximum, you can amplify the sound up to 100 dB, but the intelligibility will vary depending on the ambient noise level and the characteristics of the voice of the person you want to listen to (e.g., muffled or low voice).

For those who want to check the audibility before purchasing, we regularly hold "αble Listening Sessions" at our office in Meguro, Tokyo.

If you are interested, please contact our support center.(

We are also preparing listening sessions for people living not only in Tokyo but also in other prefectures, provinces, and prefectures.
We apologize for the inconvenience, but please wait a little longer.
