Replacing the earbud tips
M-sized earbud tips come attached to the left and right headset units at the time of purchase.
If the size of the earbud tips does not match the size of your ear canals or the headset is not being worn properly in your
ears, tap operations may not work correctly, or you may not obtain the correct sound qualities, noise canceling effects, or
call performance.
If any of this is the case, try the following.
Change the earbud tips to ones that fit more snugly in your ears. When changing the earbud tips, try the earbud tip
sizes in order from the larger ones to the smaller ones. The most suitable size of the earbud tips for left and right ears
may be different.
“INZONE Hub” or the “Sony | Headphones Connect” app will help you to determine which earbud tips suit you best to
achieve the optimal noise canceling effect, sound quality, etc.
Check that you are wearing the headset properly in your ears. Wear the headset so that the earbud tip is comfortably
situated as deep in the ear canal as possible.
Hint
The function that determines the optimal earbud tips for you measures the air-tightness of the earbud tips and determines
whether or not the headset units are being worn in your ears correctly. Select a size that fits comfortably.
Hybrid silicone rubber earbud tips

Checking the remaining battery charge
You can check the remaining battery charge of the rechargeable batteries of the headset and the charging case by the
following operations.
Checking the remaining battery charge of the headset
If the indicator (orange) on the charging case lights up when the headset units are set in the charging case or when
the charging case lid is opened or closed while both headset units are set in the charging case, the remaining battery
charge of the headset units is between 94% and 1%.
If the indicator on the charging case does not light up when the headset units are set in the charging case or when
the charging case lid is opened or closed while both headset units are set in the charging case, the remaining battery
charge of the headset units is at less than 1%.
When the remaining battery charge of the headset units drops to 20% or less while the headset
units are in use, or when the remaining battery charge of the headset units is at 20% or less when
the headset is turned on
If you hear a notification sound and the voice guidance say, “Low battery”, charge the headset as soon as possible.
When the battery becomes completely empty, you will hear a notification sound and the voice guidance say, “Battery is
empty”. Then, the headset automatically turns off.
When using the headset by connecting to a computer
When the headset is connected to a computer, the icon indicating the remaining battery charge is displayed on the
“INZONE Hub” screen in 4 levels: “100%”, “70%”, “50%”, and “20%”.
The remaining battery charge is also displayed over 100 levels in [Device Information] on “INZONE Hub”.
Checking the remaining battery charge of the charging case
If the indicator (orange) on the charging case lights up when both headset units are removed from the charging case,
or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the
charging case is between 30% and 1%. The charging case cannot sufficiently charge the headset with this remaining
level of battery charge.
If the indicator on the charging case does not light up when both headset units are removed from the charging case,
or when the charging case lid is opened or closed with no headset units stored, the remaining battery charge of the
charging case is at less than 1%. The headset cannot be charged with the charging case in this case.
Hint
You can also check the remaining battery charge of the headset unit and the charging case with the “Sony | Headphones
Connect” app.
Note
The remaining battery charge may not be properly displayed immediately after a software update or if the headset has not been
used for a long time. In this case, repeatedly charge and discharge the battery multiple times to properly display the remaining

What is noise canceling?
The noise canceling function generates antiphase sound against outside surrounding noises (such as noises in vehicles
or noises from air conditioners indoors) to reduce the surrounding noises by canceling them out.
Note
Depending on the type of noise or if it is used in a very quiet environment, you may not feel the noise canceling effects, or you
may feel that some noise is increased.
When you are wearing the headset, depending on how you wear the headset, the noise canceling effects may be decreased or a
beeping sound (feedback) may be heard. In this case, take off the headset and put it on again.
The noise canceling function works primarily on noise in the low frequency band such as vehicles and air conditioning. While
noise is reduced, it is not completely canceled.
When you use the headset in a car or a bus, noise may occur depending on street conditions.
Mobile phones may cause interference and noise. Should this occur, move the headset further away from the mobile phone.
Do not cover the microphone part on the left or right headset unit with your hand, etc. The effect of the noise canceling function or
Ambient Sound Mode may not work properly or a beeping sound (feedback) may occur. If any of this is the case, remove your
hand, etc. from the left or right microphone part.

Precautions
About smartphone radio waves and USB transceiver communication
When the USB transceiver is connected to a smartphone, depending on the radio wave situation of the smartphone,
radio wave interference to the USB transceiver may occur, and noise or audio dropout may occur, or connection may not
be possible. In such a case, perform the following steps.
Move to a location where your smartphone’s signal situation improves.
Move the headset closer to the smartphone.
Flip the side of the USB transceiver that has the slide switch and plug it back in.
On the USB transceiver/Bluetooth communications
Because USB transceiver/Bluetooth devices use the same frequency band (2.4 GHz) as wireless LAN (IEEE
802.11ax/b/g/n), microwave interference may occur and result in noise, audio dropouts, or disabled connection if this
headset is used near a wireless LAN device. In such a case, perform the following steps.
Change the frequency band of your smartphone and wireless LAN device to 5 GHz (IEEE 802.11ac).
For details, refer to the operating instructions supplied with the wireless LAN device.
Bluetooth wireless technology operates within a range of about 10 m (32.8 ft). The maximum communication distance
may vary depending on the presence of obstacles (people, metal objects, walls, etc.) or the electromagnetic
environment.
Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off the
headset and other Bluetooth devices in the following locations, as it may cause an accident:
in hospitals, near priority seating in trains, locations where inflammable gas is present, near automatic doors, or
near fire alarms.
This product emits radio waves when used in wireless mode. When used in wireless mode on an airplane, follow
flight crew directions regarding permissible use of products in wireless mode.
When connected with a Bluetooth device, the audio playback on the headset may be delayed from that on the
transmitting device due to the characteristics of Bluetooth wireless technology. As a result, the sound may not be in
sync with the image when playing games or viewing movies.
The headset supports security functions that comply with the Bluetooth standard as a means of ensuring security
during communication using Bluetooth wireless technology. However, depending on the configured settings and other
factors, this security may not be sufficient. Be careful when communicating using Bluetooth wireless technology.
Sony shall assume no responsibility for any damages or loss resulting from information leaks that occur when using
Bluetooth communications.
Bluetooth connections with all Bluetooth devices cannot be guaranteed.
Bluetooth devices connected with the headset must comply with the Bluetooth standard prescribed by Bluetooth
SIG, Inc., and must be certified as compliant.
Even when a connected device complies with the Bluetooth standard, there may be cases where the
characteristics or specifications of the Bluetooth device make it unable to connect, or result in different control
methods, display, or operation.
When using the headset to perform hands-free talking on the phone, noise may occur depending on the
connected device or the communication environment.
77
Depending on the device to be connected, it may require some time to start communications.

headset units or charging case may rise, but this is not a malfunction.
Note on static electricity
If you use the headset when the air is dry, you may experience discomfort due to static electricity accumulated on
your body. This is not a malfunction of the headset. You can reduce the effect by wearing clothes made of natural
materials that do not easily generate static electricity.
Notes on wearing the headset
After use, remove the headset from your ears slowly.
Because the headset achieves a tight seal over the ears, forcibly pressing it against your ears or quickly pulling it off
can result in eardrum damage. When wearing the headset, the speaker diaphragm may produce a click sound. This
is not a malfunction.
The long-term use of the headset may cause symptoms such as itching and irritation in the ears.
If you experience any of the above symptoms while the headset is in use, stop using it immediately and consult a
doctor or your nearest Sony dealer.
For long-term use, it is recommended that you remove the headset from your ears on a regular basis.
Other notes
Do not subject the headset to excessive shock as it is a precision device.
Do not put a smartphone with the USB transceiver connected into pants pocket or other clothing pocket. A strong
external force applied to the transceiver may cause deformation or malfunction of the USB port part of your
smartphone.
The touch sensors may not operate properly if you apply stickers or other adhesive items to the touch sensors.
The Bluetooth function may not work with a mobile phone, depending on the signal conditions and the surrounding
environment.
Do not breathe into the sound conduit (sound output tube) or microphone.
If you experience discomfort while the headset is in use, stop using it immediately.
The earbud tips may be damaged or deteriorate with long-term use and storage.

The noise canceling effects are not sufficient.
Make sure the noise canceling function is turned on. You can check the noise canceling settings with “INZONE Hub”
or the “Sony | Headphones Connect” app.
If the size of the earbud tips does not match the size of your ear canals or the headset is not being worn properly in
your ears, tap operations may not work correctly, or you may not obtain the correct sound qualities, noise canceling
effects, or call performance.
If any of this is the case, try the following.
Change the earbud tips to ones that fit more snugly in your ears. When changing the earbud tips, try the earbud
tip sizes in order from the larger ones to the smaller ones. The size of the left and right earbud tips may be
different.
“INZONE Hub” or the “Sony | Headphones Connect” app will help you to determine which earbud tips suit you
best to achieve the optimal noise canceling effect.
Hint
The function that determines the optimal earbud tips for you measures the air-tightness of the earbud tips and determines
whether or not the headset units are being worn in your ears correctly. Select a size that fits comfortably.
Check that you are wearing the headset properly in your ears. Wear the headset so that the earbud tip is comfortably
situated as deep in the ear canal as possible.
The noise canceling function is effective for noise in low frequency ranges in locations such as offices, near air
conditioners, on trains, and on planes and is not as effective for noise in higher frequencies, such as human voices.
