| Q : |
What is "playable frequency"? |
| A : |
Playable frequency is the range of frequency
that an earphone can play.
Sound travels through air as it vibrates, and the number
of the vibration is measured in Hz (hertz). Audible frequency
of humans usually ranges from 20 to 20,000 Hz.
Thus, a wider range of playable frequency means it can play
from low to high sound with good quality.
Note: A performance
cannot be judged only by the range of playable frequency.
Please note beforehand that sound quality differs depending
on the type of music (jazz, classics, rock, etc.), your audibility,
or the structure of the earphone and how it fits in your
ears. |
| Q : |
The sound can only be heard from
one side. /Noise or confined sound is heard. |
| A : |
Please make sure the plug is inserted correctly
into the headphone terminal. These cases may occur when the
plug is out of position.
Otherwise, there may be contact failures. Insert and then
pull out the plug to and from the headphone terminal two
or three times, or try to rotate the inserted plug a couple
of times.
Note: Please make sure to take off the earphone so as not to
hurt your ears with large sound or noise. |
