SRS-XB33

Charging the speaker

The speaker is capable of running on power either from an AC outlet connected by a USB AC adaptor (commercially
available) or from the rechargeable built-in lithium-ion battery.
When using the speaker for the first time, be sure to charge the built-in battery for more than 1 hour before turning on the
speaker.
With the built-in battery charged in advance, you can use the speaker solely with battery power.

1 Connect the speaker to an AC outlet to charge it.

Connect one end of the supplied USB Type-C® cable to the DC IN 5V port on the speaker and the other end to a
USB AC adaptor (commercially available), and then connect the USB AC adaptor to an AC outlet.
The speaker supports USB AC adaptors that are capable of delivering an output current of 1.5 A or 3.0 A. When
using a USB AC adaptor with an output current of 3.0 A for battery charging, be sure to use a USB Type-C® cable
(compliant with the USB standard) that supports an output current of 3.0 A. The supplied USB cable supports an
output current of up to 1.5 A. Use of any other devices is not guaranteed for battery charging.

The CHARGE indicator lights up in orange while charging is in progress.

The estimated charging time varies depending on the power output capacity of the connected USB AC adaptor
(commercially available). In addition, it may take longer than the charging time stated below depending on the type
and specification of the USB AC adaptor and USB cable. The charging time may differ from the time stated below
depending on the ambient temperature or the usage of the speaker as well.
The following time is stated as a reference.

When the recommended USB AC adaptor capable of delivering an output current of 1.5 A is connected,
charging completes in about 5 hours* and the CHARGE indicator turns off.

When using a commercially available USB AC adaptor, make sure that it is capable of delivering an output
current of 1.5 A or more. You can use a USB AC adaptor with an output current of 500 mA or more and less
than 1.5 A as well, but it may take a very long time (10 hours or more*) before charging completes. When using
such a USB AC adaptor, it is recommended that you turn off the speaker before battery charging. Use of a USB
AC adaptor with an output current of less than 500 mA is not guaranteed for battery charging.

* Time that is required to charge the empty built-in battery to its full capacity when the speaker turns off.

After you disconnect the USB cable from the speaker upon completion of battery charging, be sure to close the cap
securely.
The cap plays a very important role in maintenance of the waterproof and dust proof performance.

7
Checking the charging completion
If the built-in battery is fully charged when you connect the speaker to an AC outlet, the CHARGE indicator lights up in
orange then turns off after about 1 minute.

Checking the built-in battery level of the rechargeable built-in battery

After pressing the BATT (battery) button behind the cap on the rear side of the speaker, when the speaker is turned
on, the voice guidance listed below is output from the speaker depending on the remaining built-in battery power.
80% or more: “Battery fully charged”
60% or more: “Battery about 70%”
40% or more: “Battery about 50%”
20% or more: “Battery about 30%”
Less than 20%: “Please charge”

Hint
By using “Sony | Music Center,” you can activate/deactivate the voice guidance associated with the remaining battery power
that you hear when you turn on the speaker.

When using the Android smartphone with OS 8.1 or later installed

When the speaker is connected with the Android smartphone via an HFP (Hands-free Profile) BLUETOOTH
connection, tap [Settings] - [Device connection] - [Bluetooth] on the smartphone. The remaining battery power of the
speaker is displayed along with the connected BLUETOOTH device name. For details, refer to the operating
instructions supplied with the Android smartphone.
Note that the remaining battery power displayed on the smartphone may vary from the actual remaining battery
power of the speaker. Consider this information as a reference.

When using the iPhone/iPod touch with iOS 10.0 or later installed
While the speaker is connected with the iPhone/iPod touch via an HFP (Hands-free Profile) BLUETOOTH
connection, the remaining battery power of the speaker is displayed on the widget screen of the iPhone/iPod touch.
For details, refer to the operating instructions supplied with the iPhone/iPod touch.
Note that the remaining battery power displayed on the iPhone/iPod touch may vary from the actual remaining
battery power of the speaker. Consider this information as a reference.

Built-in battery life (using a BLUETOOTH connection)

About 24 hours
The volume level of the speaker is set to 36.
The lighting function is set to off.
The sound effect is set to STAMINA.

About 14 hours
The volume level of the speaker is set to 35.
The lighting function is set to on. (factory default settings)
The sound effect is set to EXTRA BASS. (factory default settings)

About 4 hours
The volume level of the speaker is set to maximum (50).
The lighting function is set to on. (factory default settings)
The sound effect is set to EXTRA BASS. (factory default settings)

The built-in battery life above is measured using our specified music source.
Actual performance time may vary from the listed time due to the volume, songs played, surrounding temperature, and
usage conditions.

When the built-in battery is running low

When the voice guidance says “Please charge” and the CHARGE indicator flashes slowly, the built-in battery is running
low and needs to be charged. In this state, the speaker cannot supply power to other devices.

Hint

8
 You can charge the speaker's built-in battery by connecting the USB cable connected with the speaker to a computer that comes
equipped with a USB charging port as well. However, not all the computers are tested and found compatible with this procedure
and the procedure is not applicable to home-built computers.

As long as the speaker is connected to an AC outlet by a USB AC adaptor (commercially available) or to a computer that comes
equipped with a USB charging port, the speaker's built-in battery is capable of charging itself even while music playback from the
speaker is in progress. However, it may take a long time before charging completes depending on the usage of the speaker. It is
recommended that you turn off the speaker before battery charging.

Note
Depending on the type or specifications of the USB AC adaptor, if you use the speaker at a loud volume, the remaining power of
the rechargeable built-in battery may decrease or the speaker may turn off even while the speaker is connected to an AC outlet
by the USB AC adaptor. This, however, does not indicate a malfunction. If such a case occurs, turn off the speaker and let the
battery fully charge itself before you use the speaker.

When you use the speaker at a loud volume for a long time, the built-in battery may run low even if the speaker is connected to
an AC outlet. As a result, sound becomes low. This is not a malfunction. Turn off the speaker and charge the built-in battery
sufficiently.

The maximum power output will be lower when the built-in battery is running low.

In an extremely cold or hot environment, charging stops for safety. If charging takes a long time, it also makes charging of the
speaker stop. To resolve these issues, disconnect the USB cable, and then connect it again within an operating temperature
between 5 °C and 35 °C (41 °F and 95 °F).

Do not charge the speaker's built-in battery in places where water may splash on it. The supplied USB Type-C® cable as well as
the USB port behind the cap are designed neither for waterproof nor for dust proof.

Even if you do not intend to use the speaker for a long time, charge the built-in battery sufficiently once every 6 months to
maintain its performance.

The multi-device connection is not compatible with HFP (Hands-free Profile). Therefore, when using the multi-device connection,
the remaining battery power of the speaker is not displayed on the Android smartphone or the iPhone/iPod touch.

When the Android smartphone is configured to use only A2DP (Advanced Audio Distribution Profile) for establishing
BLUETOOTH connections, the remaining battery power of the speaker is not displayed on the smartphone.

Party Connect function or terminate the Party Connect function.

The lighting mode of the speaker varies depending on the type of the speaker that is set up as the first speaker.

When using the Party Connect function, the codec automatically switches to SBC.

If the speaker is already connected with a BLUETOOTH device, touching another NFC-compatible device onto the speaker will
disconnect the BLUETOOTH connection with the previous device and establish a BLUETOOTH connection with the new device.

Note
When watching movies using the Party Connect function, there may be a gap between video and audio.

Be sure to close the cap completely after using the PARTY (Party Connect) button.
The cap plays a very important role in maintenance of the waterproof and dust proof performance.

Precautions

On safety

Refer to the Reference Guide supplied with the speaker.

Important information such as the model name is located on the inner surface of the cap on the rear side of the
speaker.

On placement

To eliminate the risk of malfunctions, avoid the following locations when placing or leaving this speaker.

A place subject to high temperatures, such as under direct sunlight or lighting equipment, near a heat source, or
in a sauna

Inside a vehicle with the windows closed (especially in summertime)

A place subject to excessive dust

A place subject to strong vibration

Place this speaker on a flat, level surface. When placed on a sloped surface, the speaker may fall over or fall off the
surface due to its own vibration, resulting in injuries, malfunctions, or performance degradation.

Depending on the conditions where this speaker is placed, it may fall over or fall off the surface. Do not leave any
valuables near the speaker.

This speaker is not anti-magnetic. Keep objects susceptible to magnetism (recorded tapes, watches, cash cards and
credit cards with magnetic coding, etc.) away from the speaker. When you carry around the speaker, keep this in
mind as well.

Do not use the speaker in a vehicle.

Others

Do not use or leave the speaker in an extremely cold or hot environment (temperature outside the range of 5 °C – 35
°C (41 °F – 95 °F)). If the speaker is used or left in outside the above range, the speaker may automatically stop to
protect internal circuitry.

When the light is strong, brighten the room or turn off the lighting.

Even if you do not intend to use the speaker for a long time, charge the battery to its full capacity once every 6
months to maintain its performance.

If you have any questions or problems concerning the speaker that are not covered in this Help Guide, consult your
nearest Sony dealer.

Notes on charging

Life span of the built-in lithium ion battery

Even if you do not intend to use the speaker for a long time, charge the built-in battery sufficiently once every 6
months to maintain its performance.

If the speaker is not used for a long time, it may take longer to charge the built-in battery.

The rechargeable built-in battery has a life span. As time passes and the number of times that the built-in battery is
used increases, the capacity of the rechargeable built-in battery slowly decreases. When the amount of time that the
built-in battery can be used seems significantly shorter, despite having been fully charged, contact your nearest Sony
dealer.

When the amount of time that the built-in battery can be used seems significantly shorter, it could mean that the
rechargeable built-in battery has expired.

The life span of the rechargeable built-in battery differs depending on the usage, environment, and storage method.

Caution

When the speaker detects a problem for the following causes while charging the built-in battery, the CHARGE indicator
(orange) turns off even if charging is not completed.

Ambient temperature exceeds the range of 5 °C – 35 °C (41 °F – 95 °F).

There is a problem with the built-in battery.

When charging to the built-in battery continues for a long time.

Note
Charging time varies depending on built-in battery usage conditions.

Charge the speaker in an ambient temperature between 5 °C and 35 °C (41 °F and 95 °F).

The speaker becomes warm during charging. This is not a malfunction.

Avoid exposure to rapid temperature change, direct sunlight, mist, sand, dust, or mechanical shock. Also, never leave the
speaker in a car parked in the sun.

As long as the speaker is connected to an AC outlet by a USB AC adaptor (commercially available), the speaker's built-in battery
is capable of charging itself even while the speaker is turned on. However, it may take a long time before charging completes
depending on the usage of the speaker. It is recommended that you turn off the speaker before battery charging.

You can charge the speaker's built-in battery by connecting the speaker to a computer that comes equipped with a USB charging
port as well. However, not all the computers are tested and found compatible with this procedure and the procedure is not
applicable to home-built computers.

Do not connect the speaker to a computer for a long period of time when the computer is not connected to an AC power supply.
Otherwise, the computer's battery may run out.

In an extremely cold or hot environment, charging stops for safety. If charging takes a long time, it also makes charging of the
speaker stop. To resolve these issues, disconnect the USB cable from the speaker and connect it again within an operating
temperature between 5 °C and 35 °C (41 °F and 95 °F).

At high temperature, the charging may stop or the volume may reduce to protect the battery.

76
 Use of a USB hub is not guaranteed for battery charging.

protection against water immersion” of the IEC60529 “Ingress Protection Rating (IP Code)”*3, and a dust proof
specification of IP6X*2 as specified in “Degrees of protection against solid foreign objects”*3.

Liquids that the waterproof performance specifications apply to

Applicable fresh water, tap water, pool water, salt water

Not liquids other than the above (soapy water, water with detergent or bath agents, shampoo, hot spring
applicable water, etc.)

*1 IPX7 equivalency: The speaker has been tested to and maintains its operability when gently submersed in water to a depth of 1 m (3.2 ft) and
left for 30 minutes.
*2 IP6X equivalency: The speaker has been tested to and continues to block dust after stirring for 8 hours in a testing device which contains dust
particles that are up to 75 μm in diameter.
*3 The supplied accessories and the connectors of this speaker (USB) are neither waterproof nor dust proof. To reduce the risk of fire or electric
shocks, do not expose the speaker to water or droplets while using either or both of the connectors (USB). Do not place a vase or any other
liquid-filled container on the speaker.

The waterproof and dust proof performance of the speaker is based on our measurements under the conditions herein
described. Note that malfunctions as a result of water immersion or dust intrusion caused by misuse by the customer are
not covered by the warranty.

To avoid the deterioration of the waterproof and dust proof performance

Check the following and use the speaker correctly.

The speaker passes the drop test from 1.22 m (4 ft) on plywood of 5 cm (2 in) thickness conforming to MIL-STD810H
Method 516.8-Shock. However, this does not guarantee no damage, no breakdown, or waterproof and dust proof
performance in all conditions. Deformation or damage from dropping the speaker or subjecting it to mechanical shock
may cause deterioration of the waterproof and dust proof performance.

This speaker does not have a design that is resistant to water pressure. Use of the speaker in a location where high
water pressure is applied, such as in the shower, may cause a malfunction.

Do not pour high-temperature water or blow hot air from a hair dryer or any other appliance on the speaker directly.
Also never use the speaker in a place subject to high temperatures, such as in a sauna or near a heat source.

Handle the cap with care. The cap plays a very important role in maintenance of the waterproof and dust proof
performance. When using the speaker, make sure that the cap is closed completely. When closing the cap, be
careful not to allow foreign objects inside. If the cap is not closed completely the waterproof and dust proof
performance may deteriorate and may cause a malfunction of the speaker as a result of water or dust particles
entering the speaker.

How to care for the speaker

Although the fabric part of the speaker has water repellent treatment applied, you can use the speaker more comfortably
and for a longer period of time by following the maintenance procedure below.

When the speaker surface is soiled, immediately wash off the soil with fresh water (tap water, etc.). Leaving the soil
on the surface will cause the fabric part or the passive radiator section to discolor or deteriorate, or cause the
speaker to malfunction.
Ex.

When salt, sand, etc. is stuck on the speaker after using it on a beach, pool side, etc.

When the speaker is stained with foreign substances (sunscreen, suntan oil, etc.)

If the speaker gets wet, wipe off the moisture using a dry soft cloth immediately. In addition, dry the speaker in an airy
place until no moisture remains.

The sound quality may change if water enters the speaker or passive radiator section ( ). This, however, does not
indicate a malfunction. Wipe off the moisture on the speaker surface and leave the speaker on a dry soft cloth to let
the water drain out from inside the speaker. Then, leave the speaker in a well-ventilated place to let it dry out.

Note
If the surface of the speaker gets dirty, do not use detergent, thinner, benzine, alcohol, etc. to clean the speaker because it will
affect the water repellent function of the fabric part of the speaker.

Especially in cold regions, be sure to wipe off the moisture after using the speaker. Leaving moisture on its surface may cause
the speaker to freeze and malfunction.

If particles, such as sand grains, enter the fabric or other part of the speaker, remove them with care. Never use a vacuum
cleaner or an equivalent for removal as it may damage the speaker or other unit.

About the BLUETOOTH wireless technology

The BLUETOOTH wireless technology operates within a range of about 30 m (about 98 ft).

Supported version and profiles of the BLUETOOTH standard

A profile is a set of functions standardized for every characteristic of BLUETOOTH devices. The speaker supports the
following version and profiles of the BLUETOOTH standard.
Supported BLUETOOTH version: BLUETOOTH standard, version 5.0
Supported BLUETOOTH profiles:

A2DP (Advanced Audio Distribution Profile): Enables transmission and reception of high-quality music contents.
AVRCP (Audio Video Remote Control Profile): Enables volume adjustment and operations to play/pause music and
skip to the beginning of the next/current track.
HSP (Headset Profile)*: Enables phone call making and mobile phone operations.
HFP (Hands-free Profile)*: Enables hands-free phone call making and mobile phone operations.

* If the mobile phone with the BLUETOOTH function supports both HFP and HSP, use HFP (Hands-free Profile).

Maximum communication range

Use the BLUETOOTH wireless technology between the speaker and a device that are located within 30 m (about 98 ft)
from each other.
Maximum communication range may shorten under the following conditions.

There is an obstacle such as a person, metal, or wall between the speaker and BLUETOOTH device.
A wireless LAN device is in use near the speaker.
A microwave oven is in use near the speaker.
A device that generates electromagnetic radiation is in use near the speaker.

Interference from other devices

Because BLUETOOTH devices and wireless LAN (IEEE802.11b/g) use the same frequency (2.4 GHz), microwave
interference may occur and result in communication speed deterioration, noise, or invalid connection if the speaker is
used near a wireless LAN device.

Interference to other devices

Microwaves emitted from a BLUETOOTH device may affect the operation of electronic medical devices. Turn off the
speaker and other BLUETOOTH devices in the following locations, as it may cause an accident.

Where inflammable gas is present, in a hospital, train, airplane, or a gas station

Near automatic doors or a fire alarm

Note
To be able to use the BLUETOOTH function, the BLUETOOTH device to be connected requires the same profile as the
speaker’s. Note also that even if the same profile exists, devices may vary in function depending on their specifications.

Due to the characteristic of BLUETOOTH wireless technology, the sound played on the speaker is slightly delayed from the
sound played on the BLUETOOTH device while talking on the telephone or listening to music.

The speaker supports security capabilities that comply with the BLUETOOTH standard to provide a secure connection when the
BLUETOOTH wireless technology is used, but security may not be enough depending on the setting. Be careful when
communicating using BLUETOOTH wireless technology.

81
We do not take any responsibility for the leakage of information during BLUETOOTH communication.

A device featuring the BLUETOOTH function is required to conform to the BLUETOOTH standard specified by the Bluetooth SIG,
Inc. and be authenticated. Even if the connected device conforms to the above mentioned BLUETOOTH standard, some devices
may not be connected or work correctly, depending on the features or specifications of the device.

Noise or sound interruption may occur depending on the BLUETOOTH device connected with the speaker, the communication
environment or the usage environment.

A device with a built-in radio or tuner cannot be connected to the speaker via BLUETOOTH since noise may occur in broadcasts.

Locate the speaker farther away from a TV, radio or tuner, etc. since noise may occur in broadcasts.

Unable to charge the speaker

When a USB AC adaptor (commercially available) is in use, make sure that the USB cable is connected securely to
the speaker and the USB AC adaptor. Then, make sure that the USB AC adaptor is connected securely to an AC
outlet.

When using a USB AC adaptor (commercially available), make sure that it is capable of delivering an output current
of 1.5 A or more. You can use a USB AC adaptor with an output current of 500 mA or more and less than 1.5 A as
well, but it may take a very long time (10 hours or more) before charging completes. When using such a USB AC
adaptor, it is recommended that you turn off the speaker before battery charging. Use of a USB AC adaptor with an
output current of less than 500 mA is not guaranteed for battery charging.

The speaker supports USB AC adaptors that are capable of delivering an output current of 1.5 A or 3.0 A. When
using a USB AC adaptor with an output current of 3.0 A for battery charging, be sure to use a USB Type-C® cable
(compliant with the USB standard) that supports an output current of 3.0 A. The supplied USB cable supports an
output current of up to 1.5 A. Use of any other devices is not guaranteed for battery charging. The charging time may
vary depending on the ambient temperature or the usage of the speaker as well.

You can charge the speaker's built-in battery by connecting the USB cable connected with the speaker to a computer
that comes equipped with a USB charging port as well. However, not all the computers are tested and found
compatible with this procedure and the procedure is not applicable to home-built computers.

Depending on the type or specifications of the USB AC adaptor, if you use the speaker at a loud volume, the
remaining power of the rechargeable built-in battery may decrease or the speaker may turn off even while the
speaker is connected to an AC outlet by the USB AC adaptor. This, however, does not indicate a malfunction. If such
a case occurs, turn off the speaker and let the battery fully charge itself before you use the speaker.
