Listening to audio from the 
headphones and TV speakers 
simultaneously

Connect the transmitter to your Cable Box/Satellite Box 
rather than your television.
Some TVs can be set to output audio from both its 
speakers and headphone jack. For details on the 
setting, refer to the operating instructions of your TV.

Note on monaural component 
connection

If you connect the transmitter directly to an earphone 
jack (monaural mini jack) of an A/V component, the 
audio signal may not be output through the right 
channel.

Tips for charging

Charge the headphones first

The headphones contain a rechargeable Lithium-Ion 
battery, which should be charged before using for the first 
time.

Charging and usage time

Approx. charging time

Approx. usage time

1)

3 hours

2)

10 hours

3)

1) at 1 kHz, 0.1 mW + 0.1 mW output
2) hours required to fully charge an empty battery
3) Time may vary, depending on the temperature or 

conditions of use.

Remaining battery

To check the remaining battery charge of the headphones, 
turn them on, and check the 

/

 indicator. The battery is 

still serviceable when the indicator lights up green. Charge 
the headphones if the 

/

 indicator turns off, dims, 

flashes, or the sound becomes distorted or noisy.

To charge the headphones from an 
AC outlet

If you recharge the headphones by connecting to an AC 
outlet, use the USB AC Adaptor (not supplied). For more 
information, refer to the operating instructions supplied 
with the adaptor.

Notes

ˋ

ˋ

Use only the supplied micro-USB cable. Do not use any 
other USB cable.

ˋ

ˋ

If the headphones are not used for a long time, the CHG 
indicator may take a while to light after you connect it 
to the computer. In this case, do not disconnect the 
micro-USB cable from the headphones and wait until 
the CHG indicator lights up.

ˋ

ˋ

Charge the headphones in an ambient temperature of 
between 5 °C to 35 °C. If you try to charge the 
headphones in an ambient temperature outside this 
range, the CHG indicator may flash and charging will 
not be completed properly.

ˋ

ˋ

If the computer enters hibernation mode while 
connected to the headphones, charging will not be 
completed properly. Check the setting of the computer 
before charging. The CHG indicator will turn off 
automatically when the computer enters hibernation. 
Charge the headphones again in this case.

ˋ

ˋ

Connect the headphones directly to a computer. 
Charging may not be completed properly by an indirect 
connection, such as via a USB hub.

ˋ

ˋ

When the battery life reduces to half, this may be the 
end of battery lifetime. For how to change batteries, 
consult your place of purchase or a Sony dealer.

Tips for volume setting

ˋ

ˋ

If you connect the transmitter to the headphone jack of 
the A/V component, set the volume of the A/V 
component as high as possible but not so high that the 
audio signal becomes distorted.

ˋ

ˋ

When watching videos, be careful not to raise the 
volume too high in quiet scenes. You may hurt your 
ears when a loud scene is played.

RF signal transmission 
area

The approximate RF signal transmission area from the 
transmitter is up to 30 m.
The sound may be interrupted if the headphones are out 
of RF signal transmission area, or reception conditions 
deteriorate.

Notes

ˋ

ˋ

Because this system transmits signals at 2.4 GHz, sound 
may be interrupted if interference occurs. This is due to 
radio frequency characteristics, and is not a 
malfunction.

ˋ

ˋ

Any noise you hear through the headphones may vary 
depending on the transmitter position and room 
conditions. It is recommended that you place the 
transmitter in a location that produces the clearest 
sound.

ˋ

ˋ

Sound may be interrupted if the transmitter is used 
with other wireless apparatus using 2.4 GHz frequency, 
or a microwave oven.

Replacing the earpads

The earpads are replaceable. If the earpads become dirty 
or worn out, replace them as illustrated below. The 
earpads are not commercially available. You can order 
replacements from the store where you purchased this 
system, or at your nearest Sony dealer.

Remove the old earpad by pulling it out of the groove 
on the housing.

Fit the new earpad in the groove of the housing.
Make sure the earpad is set to the vertical position.

If you run into any problems using this system, use the 
following checklist. Should any problem persist, consult 
your nearest Sony dealer.

Insert the AC adaptor plug firmly.

ˋ

ˋ

Be sure to use the supplied AC adaptor. Using AC 
adaptors with different plug polarity or other 
characteristics can cause product failure.

Unified 
polarity plug

ˋ

ˋ

Be sure to always use the supplied AC adaptor. Even AC 
adaptors having the same voltage and plug polarity can 
damage this product due to the current capacity or 
other factors.

On power sources and placement

ˋ

ˋ

If you are not going to use the system for a long time, 
unplug the AC adaptor from the AC outlet. When 
removing the plug, grip the AC adaptor. 
Do not pull on the cord.

ˋ

ˋ

Do not place the system in any of the following 
locations.

ˋ

ˋ

Location exposed to direct sunlight, near a heater, or 
other extremely high-temperature location

ˋ

ˋ

Dusty location

ˋ

ˋ

On an unsteady or inclined surface

ˋ

ˋ

Location exposed to large amounts of vibration

ˋ

ˋ

Bathroom or other high-humidity locations

On headphones

Act considerately

When the volume is too high, the sound leaks outside the 
headphones. Be careful not to raise the volume so high 
that it bothers people around you.
There is a tendency to raise the volume when using in 
noisy places. However, for reasons of safety, it is advised 
to keep the volume at a level whereby you can still hear 
sounds around you.

On cleaning

Use a soft cloth slightly moistened with mild detergent 
solution. Do not use solvents such as thinner, benzene or 
alcohol as these may damage the surface.

When the product breaks

ˋ

ˋ

When the product breaks, or if a foreign object gets 
inside the unit, immediately turn off the power and 
consult your nearest Sony dealer.

ˋ

ˋ

When taking the system to a Sony dealer, be sure to 
take both the headphones and transmitter.
