Getting started
1. Waking up the earbuds and the charging case
and charging the rechargeable batteries
Upon delivery, the rechargeable batteries of the earbuds and the
charging case are in sleep mode and have to be woken up by connecting them to a power source once.
▷ Remove the protective foils from the earbuds.
▷ Insert the earbuds into the charging case.
▷ Close the lid of the charging case.
▷ Open the protective cover of the USB socket of the charging box.
Connect the USB-C cable to the charging case and to a USB
power source (> 14).
The earbuds and the charging case are woken up and the
rechargeable batteries are being charged. The earbuds are now
ready for use.
2. Selecting “Adaptable Acoustics” with suitable ear adapters and ear fins for optimum fit of
the earbuds
The perceived sound quality including bass performance for the
“Adaptable Acoustics” feature of the SPORT True Wireless depends
to a large extent on the correct fit of the earbuds in the ear. Earbuds
that fit perfectly in your ears do not fall out even during fast movements and, especially for “Focus” mode, the best possible noise cancellation is ensured. Therefore, you can choose between ear adapters and ear fins in different sizes.

Open ear adapters for “Aware” mode
Use the open ear adapters (with blue marking inside) for “Aware”
mode, for example to reduce body borne noise when running
(breathing, footsteps, clothes rattling) and to be more aware of high
sounds from your surroundings (car horn, bike bell, barking dog).
Closed ear adapters for “Focus” mode
Use the closed ear adapters (with a black cross inside) for “Focus”
mode to minimize your awareness of your surroundings and to fully
immerse yourself in your favorite music, for example, when working
out at the gym or at home.
Proceed as follows:
▷ Test which ear adapter size is best for “Aware” or “Focus” mode
and which ear fins give you the best sound quality and the best
wearing comfort.
▷ You can choose between open and closed ear adapters in size S,
M and L (> 21) and 4 different ear fins in size N, S1, S2 and S3 (>
21). You may need different ear adapter sizes for your right or left
ear.
▷ In the Smart Control app, select the suitable mode for the open or
closed ear adapters used under “Adaptable Acoustics”, (> 23).
▷ Assign the right earbud to your right ear and the left earbud to
your left ear.
▷ Insert the earbuds at a slight angle into the ears and twist them
slightly into the ear canal so that they sit comfortably and snugly
in the ear canal.
3. Connecting the earbuds to a Bluetooth device
Connect the earbuds to your smartphone via Bluetooth (> 17).

Information on the rechargeable battery, the charging process and the first use
The earbuds and the charging case each have a built-in rechargeable
battery. The charging case allows you to store the earbuds safely at
all times while on the go, and they are being charged at the same
time.
Upon delivery, the reachargeable batteries of the earbuds and the
charging case are in sleep mode. Remove the protective foil on the
charging contacts of the earbuds and connect the charging case to
a USB power source to exit sleep mode.
A complete charging cycle of the charging case and the earbuds
takes about 1.5 hours. The quick charge function gives you approx. 1
hour of playback time after 10 minutes of charging. The charging
time can vary depending on the power source used and the ambient
temperature.
We recommend charging the earbuds and the charging case for a
complete charging cycle without interruption before using for the
first time.
We recommend using the supplied USB cable and a compatible
standard USB power supply for charging the headphones.
When a USB cable connected to a power source is also connected to
the charging case, the rechargeable battery of the charging case is
being charged. When the earbuds are inserted into the charging
case, their rechargeable batteries are being charged at the same
time. The LED of the charging case displays the charge status (> 8).
When the battery charge of the earbuds drops to a critical level, a
voice prompt asks you to recharge the earbuds (“Recharge headset”).
The charge status of the rechargeable battery of the charging case
is displayed by the LED on the charging case (> 8).
At the end of its operational lifetime, this product with its built-in
rechargeable battery must be disposed of separately from normal
household waste. You can find more information here: > 39.

Connecting the earbuds to a Bluetooth device
To be able to use the Bluetooth wireless connection, you must register both devices (earbuds and e.g. smartphone) via the device settings of your smartphone. This process is called pairing.
If operation differs from the steps mentioned, also refer to the
instruction manual of the Bluetooth device you are using.
When you switch on the earbuds for the first time after initial
charging, they automatically switch to Bluetooth pairing mode.

Information on the Bluetooth wireless connection
The earbuds are compatible with Bluetooth 5.2.
If your audio source supports one of the following high-resolution
audio encoding methods, music is automatically played in high audio
quality: aptX® or AAC. Otherwise the headphones will play your
music in normal audio quality (SBC).
Paired devices establish the Bluetooth wireless connection immediately after switch-on and are ready for use.
When you switch on the earbuds, they automatically try to connect
to the last connected Bluetooth device. The earbuds can save the
connection profiles of up to eight Bluetooth devices with which they
have been paired. Audio playback is only possible from one device at
a time.
If you pair the earbuds with the ninth Bluetooth device, the saved
connection profile of the least used Bluetooth device will be overwritten. If you want to re-establish a connection with the overwritten
Bluetooth device, you have to pair the earbuds again.
Using the Smart Control app, you can view the list of paired devices
and selectively connect and disconnect devices (“Connections”; >
17).

Setting “Adaptable Acoustics” to match the ear adapters
Using the “Adaptable Acoustics” feature in Smart Control app and
the open or closed ear adapters, you can optimally adapt the SPORT
True Wireless to your application.
Note that both earbuds must be switched on to adjust the settings
for both earbuds (right and left).
▷ If you use the closed ear adapters, activate “Focus” mode.
▷ If you use the open ear adapters, activate “Aware” mode (default
setting upon delivery).
If the “Adaptable Acoustics” settings in the Smart Control app
and the mounted ear adapters do not match correctly, the
SPORT True Wireless are fully usable, but the sound quality –
especially the bass performance – is not optimal.
Inserting the earbuds into the ears
▷ Assign the right earbud to your right ear and the left earbud to
your left ear.
▷ Insert the earbuds at a slight angle into the ears and twist them
slightly into the ear canal so that they sit comfortably and snugly
in the ear canal (> 21). If you are using an ear fin, make sure that
the fin finds support in the auricle (> 21).
The right or left earbud can be used alone. If you insert one
earbud into the charging case during use, a short interruption
of playback may occur in the other earbud.

Using the Auto Call function
If you take the paired earbuds out of the charging case during an
incoming call, the call is automatically accepted and you can use the
earbuds directly for making calls.
You can activate (default setting) or deactivate the function via the
Smart Control app. Note that both earbuds must be switched on to
adjust the settings for both earbuds (right and left).

earbud into the charging case during use, a short interruption
of playback may occur in the other earbud.

When using the earbuds for phone calls, you may find it more comfortable if your own voice is audible in the earbuds. With the
Sidetone function activated, your own voice is played back through
the earbuds during a phone call.
You can activate the function (default setting) and adjust settings or
deactivate the function via the Smart Control app. Note that both
earbuds must be switched on to adjust the settings for both earbuds
(right and left).
The right or left earbud can be used alone. If you insert one
earbud into the charging case during use, a short interruption
of playback may occur in the other earbud.

Leaving the Bluetooth transmission range
Wireless calling and streaming are only possible in the Bluetooth
transmission range of your smartphone. The transmission range
largely depends on environmental conditions such as wall thickness,
wall composition etc. With a free line of sight, the transmission
range of most smartphones and Bluetooth devices is up to 10 meters.
If you, and therefore the earbuds, leave the Bluetooth transmission
range of the smartphone, the sound quality deteriorates increasingly
until you hear the voice prompt “No connection” and the connection
breaks down completely. If you immediately re-enter the Bluetooth
transmission range, the connection is automatically re-established
and you hear the voice prompt “Connected”. If this is not the case,
tap the touch control panel of the earbud 1x.
Resetting the earbuds
If the function of the earbuds is disturbed, perform a reset. Individual
settings such as the pairing settings are not deleted.
▷ Insert both earbuds into the charging case, close the lid of the
charging case and wait at least 10 seconds before taking the earbuds out of the charging case and switching them on again.

Smart Control app.
▷ If the Smart Control app is not available, pair the earbuds with
