On water resistant performance of the headset
The charging case is not water resistant.
The water resistant specifications of this headset are equivalent to IPX4 in IEC 60529 “Degrees of protection against
ingress of water (IP Code)”, which specifies the degree of protection provided against the entry of water. The headset
cannot be used in water.
Unless the headset is used correctly, water may get into the headset and cause fire, electrocution, or malfunctions.
Note the following cautions carefully and use the headset correctly.
IPX4: Protected against water splashing from any direction.
The sound conduits (sound output tubes), air holes, and microphone holes (in 2 locations) of the headset are not
completely watertight.
If any water droplets are left in the sound conduits, air holes, or microphone holes (in 2 locations), the following
symptoms may occur temporarily, but they are not malfunctions.
Sounds become difficult to hear.
The noise canceling effect is weakened.
Unusual sounds are heard.
Voices during phone calls become difficult to hear.
Liquids that the water resistant performance specifications apply to
The water resistant performance of the headset is based on measurements performed by Sony under the conditions
described above. Note that malfunctions resulting from water immersion caused by customer misuse are not covered by
the warranty.
