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
Applicable: Fresh water, tap water, perspiration
Not Liquids other than those above (examples: soapy water, detergent water, water with bath agents,
applicable: shampoo, hot spring water, hot water, pool water, seawater, etc.)
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.
To maintain water resistant performance
Carefully note the precautions below to ensure proper use of the headset.
Do not splash water forcibly into the sound output holes.
Do not drop the headset into water, and do not use underwater.
Do not allow the headset to remain wet in a cold environment, as the water may freeze. To prevent malfunction,
make sure to wipe off any water after use.
Do not place the headset in water or use it in a humid place such as a bathroom.
Do not drop the headset or expose it to mechanical shock. Doing so may deform or damage the headset, resulting in
deterioration of water resistance performance.
If the headset gets wet,
1.
Use a soft dry cloth to wipe off any water that gets on the headset.
2.
Remove the earbud tips, position the sound conduits and the air holes downward, and shake several times to get
the water out.
3.
Turn the microphone holes (in 2 locations) downward and gently tap them about 5 times on a dry cloth, etc. to
remove any water collected inside.
4.
After completing these steps, leave the headset to dry in room temperature.
If the headset units are charged while they are wet with sweat, etc., the charging ports will corrode. Before charging,
wipe off any moisture with a soft dry cloth and leave to dry in room temperature.
