Troubleshooting
No sound, noise, or sound interruption occurs in the wired Headphones or Earbuds
IMPORTANT: The following solutions are applicable to cases when the headphones and playback device are
connected directly with a cable.
No sound
Make sure that the headphone plug is properly connected to the device.
NOTE: It is possible that the headphone plug has not been inserted properly due to some rigidness of the headphone
jack on the device used (music player, smartphone, tablet, etc.). Make sure the plug is completely inserted into the
device.
In cases when sound cannot be heard from the right channel of the headphones, check if the device the headphones
are connected to is equipped with a monaural output. If the device cannot play stereo sound, the headphones will
not replicate stereo sound. This is due to the specification of the device and is not a failure. Test this by connecting
the headphones to a device equipped with a stereo output (e.g. digital music player) and check if sound can be heard
from both channels.
Check if the playback device is functioning.
NOTE: This can be checked by turning up the volume of the playback device or by connecting a different pair of
headphones to the playback device.
Noises can be heard
Connect a different pair of headphones to the device and check if noises are being generated.
Check if noises can be heard in a state where the cable is not in contact with clothing, etc.
NOTE: There are cases when noise from the cable brushing against clothes can be heard through the cable. This noise
may be reduced by using a clip for the cable.
When noises can be heard when the headphones are connected to a monitor or mixer equipped with a headphone
terminal, it is possible that the monitor or the mixer is the source of the noise.
Check if noises can still be heard when connecting a different pair of headphones to the device, or if noises can be
heard when connecting the headphones to a different source of sound.
In cases when crackling or popping sounds can be heard when mounting canal-type headphones on the ears, this is
not a failure. Such sounds may be created due to the earbuds not being stable immediately after they are mounted.
Continue use as these sounds will go away after a while.
Depending on the device the headphones are connected to, the sound may become distorted or cracked, or noise
may be generated when the volume is turned up. In such case, use the headphones with the volume turned down.
WARNING: There is a risk of personal injury. Prolonged use under large volumes that stimulate the ears may have
adverse effects on hearing. Be careful not to turn the volume up too high to prevent damaging your ears.
Interrupted sound
Connect a different pair of headphones to the playback device and check if the song, etc. being played by the playback
device is still being interrupted.
Check if the remaining battery level of the playback device is sufficient.
NOTE: Sound may be interrupted when the remaining level of the dry cell batteries or built-in battery is low.
Make sure that the headphone plug is properly connected to the device.
