Noise is heard during music playback.

  • When you use the headset while you are walking or running, the sound of vibrations may be heard through your body, but this is due to the characteristics of the product and not a malfunction.
  • The sound conduits (sound output tubes), air holes and microphone hole of the headset are not completely watertight. If any water droplets are left in the sound conduits, air holes or microphone hole, a beeping sound (feedback) may be heard temporarily. This is not a malfunction.
