Note

  • If you are listening to music loudly with the headphone amplifier connected to a Mac, the POWER/CHG indicator may flash in green or the sound may be interrupted. This is not a malfunction. In this case, turn the volume down.
  • The headphone amplifier is not guaranteed to operate via a USB hub or USB cable extension. Use the supplied micro-USB cable only.
  • Do not disconnect the Mac while operating. Before disconnecting the Mac from the headphone amplifier, stop playback and turn the headphone amplifier off to prevent damage to data.
  • Digitally broadcast sound may not be able to be output from a Mac’s USB port.
  • If you are listening to music too loudly, the battery may drain even if the DC IN 5V port of headphone amplifier is connected to a Mac or an AC outlet.
  • Be careful not to trip over the connecting cable.
  • The WALKMAN/Xperia/PC connection INPUT port has priority when multiple devices are connected to the WALKMAN/Xperia/PC connection INPUT port and the iPhone/iPad/iPod connection INPUT port at the same time.
