Sound cuts out on the headphones (WH-L600)

Depending on the product environment, distorted or intermittent sound (sometimes with some sort of noise) can occur.
This can have several reasons: check the following issues and try their solutions.

• The battery of the headphones might be low
  • Sufficiently charge the headphones battery
     
• Check your environment
  • Make sure there are no other wireless devices using the 2.4 GHz wireless frequency band (or a microwave oven) active around the processor and headphones.
  • Try changing the position of the processor 
     
• You might have selected a different input
  • When the input of the processor is set to [ANALOG], set the GAIN switch on the processor to [LO].
     
• The volume level might be too loud and causes the sound to distort
  • If you connect the headphone jack of the AV device to the AUDIO IN jack of the processor, decrease the volume level on the connected AV device.
     
• The audio output signal frequency is too high
  • This system is compatible with 96 kHz. Set the output signal to 96 kHz on the device connected to the processor. When inputting a 192 kHz signal, a disturbing sound may be output for a moment. It is not a malfunction. 
     
• Try the OPT terminal
  • If there is an OPT terminal on the connected device, use an OPT cable to connect the device to the processor, and set the input of the processor to OPTICAL.
     
• Is the power indicator still off after you have sufficiently charged the battery?
  • Take your headphones to your nearest Sony dealer.
