Getting started
1. Waking up the earbuds and the charging case and charging the rechargeable batteries
L R
USB-C USB-A

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

closed

open

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.

SPORT True Wireless | 11

Getting started

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).

Using the earbuds

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.

charging case (at least 30 minutes) until the LED lights up again.
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.

SPORT True Wireless | 15

Using the earbuds

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).

Paired and connected Bluetooth device
Paired Bluetooth device (currently not connected)
The right and the left earbud also use a Bluetooth wireless connection. Both earbuds are paired with each other upon delivery. If you are using a different earbud (e.g. a spare earbud), the two earbuds must also be paired with each other (> 18).

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).
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 Sidetone function
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.
The advantages of the Sidetone function are particularly noticeable when using the closed ear adapters.
Displaying the battery charge status
When the earbuds are connected to your Bluetooth device, the battery charge status can be displayed on the screen of your smartphone or device (depending on the device and operating system used). The Smart Control app also displays the charge status of the earbuds’ rechargeable batteries. Displaying the battery charge status using the charging case

These sound settings are active even without using the Smart Control app, i.e. when you are using a different Bluetooth device. Note that both earbuds must be switched on to adjust the settings for both earbuds (right and left).
The Sound Check function of the Smart Control app allows you to create customized equalizer presets. Sound Check guides you step by step to the optimal results.
Setting the voice prompts/beep sounds
To be able to set the voice prompts and beep sounds, you require the Smart Control app (> 20). You can choose between voice prompts and beep sounds, or deactivate the status messages with a few exceptions (e.g. rechargeable battery is empty). Note that both earbuds must be switched on to adjust the settings for both earbuds (right and left).
Customizing the control functions
To be able to customize the control functions for music playback, you require the Smart Control app (> 20). The app allows you to customize the control functions and other commands of the earbuds, to select preset control functions or to switch off the control functions. Some basic functions cannot be changed (e.g. call control).

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.
