First I ordered lightly on my ear. Of course, you can hear the sound normally.


Because the smartphone body vibrates, it sounds even if you put your ears on the bottom.


It is possible to talk even if turning the back side. In fact, even if you press the main body against the back side of the ear, it sounds like it sounds like "You can talk if you just hit the main body on your ear anyway" because you heard it properly.


Next, I wear a canal type earphone and listen to music and call.


Apart from the music that keeps flowing, clearly the sound of the phone is heard.


I tried wearing headphones with high sound insulation ... ...


Can talk without problems. Although it may not be a big prominent feature, considering it from the viewpoint of "usability of telephone", it can be said that it is a very convenient function.
