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" 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
The size of the earbud tips can be determined based on the color of the inside of the earbud tips.
SS size: red S size: orange M size: green LL size: purple
1 Remove the earbud tip. Hold the headset unit and twist the earbud tip while rotating it to pull it out. Do not pinch the end of the earbud tip when removing it.
2 Attach the earbud tip. Push the earbud tip firmly onto the sound conduit (sound output tube) on the headset so that the earbud tip covers the inner end of the sound conduit. Do not attach the earbud tip in a loose or skewed manner.

Using only one headset unit
You can remove one headset unit from the charging case and use the headset unit by itself. In this case, only the headset unit that has been removed from the charging case will turn on.
When you put on the other headset unit
The left and right headset units are automatically connected, and you can hear the audio from the game, voice chat, music or call from both units.
Assigning functions to the touch sensors
Depending on the headset unit you are wearing, some functions may not be available in the factory settings. In this case, you can change the function assignments to the touch sensors using "INZONE Hub".
Hint
In the factory settings, the volume adjustment function is assigned to the right headset unit.

Hint
The headset can be also charged by connecting the charging case to a running computer using the supplied USB Type-C cable. The headset can be charged even when the USB transceiver is set in the charging case.
Note
When charging via USB, be sure to use the supplied USB Type-C cable. Using a different cable may prevent charging. 25

Charging may not be successful depending on the type of USB AC adaptor. Depending on the settings for the headset functions and usage conditions, the speed of energy consumption for the rechargeable battery may vary between the left and right headset units. As a result, the charging time of the rechargeable batteries for the left and right headset units may differ. However, this is not a malfunction. The headset cannot be charged when the computer goes into standby (sleep) or hibernation mode. In this case, change the computer settings, and start charging once again. If the indicator (orange) on the charging case lights up for about 3 seconds and then turns off when the left and right headset units are removed from the charging case, the remaining battery charge of the charging case is low. Charge the charging case. If the indicator on the charging case does not turn on even when the left and right headset units are removed from the charging case, the battery charge of the charging case is empty. Charge the charging case. If the headset is not used for a long time, the rechargeable battery usage hours may be reduced. However, the battery life will improve after charging and discharging several times. If you store the headset for a long time, charge the battery once every 6 months to avoid over-discharge. If the headset is not used for a long time, it may take longer to charge the battery. Be sure to close the charging case lid to prevent the battery of the charging case from being consumed. If there is a problem with the rechargeable battery of the headset or the charging case and something unusual is detected during charging, the indicator (orange) on the charging case flashes. It is recommended to charge in a place with an ambient temperature between 15 °C and 35 °C (59 °F - 95 °F). Charging outside of this range may result in less efficient charging. If the problem persists, consult your nearest Sony dealer. If the headset is not used for a long time, the indicator (orange) on the charging case may not immediately light up when charging. Wait a moment until the indicator (orange) lights up. If the usage hours of the built-in rechargeable battery decrease significantly, the battery should be replaced. Consult your nearest Sony dealer. Avoid exposure to extreme temperature changes, direct sunlight, moisture, sand, dust, and electrical shock. Never leave the headset in a parked vehicle. When connecting the charging case to a computer, use only the supplied USB Type-C cable, and be sure to directly connect them. Charging will not be properly completed when the charging case is connected through a USB hub. The headset and the charging case may become warm during charging or for a while after charging. However, this is not a malfunction.

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.
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 battery charge.

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.
68

Depending on the device to be connected, it may require some time to start communications.
Note on temperature rise
While charging the headset units or charging case, or when using the headset for a long time, the temperature of the 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. If water or foreign matter enters the headset, it may result in fire or electric shock. If water or foreign matter enters the headset, stop use immediately and consult your nearest Sony dealer. In particular, be careful in the following cases.
When using the headset near a sink or liquid container Be careful that the headset does not fall into a sink or container filled with water. When using the headset in the rain or snow, or in humid locations
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. When the charging ports of the headset units or charging case get dirty, wipe them clean with a soft dry cloth.
Cleaning the headset
When the headset exterior is dirty, wipe it clean with a soft dry cloth. If the headset is particularly dirty, soak a cloth in diluted neutral detergent, and wring it well before using it to clean the headset. Do not use solvents such as alcohol, thinner, or benzene, as they may damage the finish on the surface of the headset or cause other damages.
Do not use the headset units, charging case or USB transceiver near medical devices
