Controls

Getting Started

Powering on & off

• Press and hold the power button (1) for 1.5 seconds to switch the headphones on or off.
• The headphones switch off automatically after 10 minutes without an audio signal or user input.
• You can change the auto-off timer in the Teufel Headphones app.

Connecting to the headphones

1. Press and hold the power button (1) for 1.5 seconds to switch on the headphones.
2. If the device list (memory) of the headphones is empty (no previously connected devices), the status LED (2) will flash blue rapidly. The headphones are now in Bluetooth pairing mode and emit a repeating system sound.

[Notice] If the device list of the headphones is not empty (devices are already connected), the status LED (2) lights up blue. The headphones are now in connection mode and automatically connect to already connected devices if they are within the Bluetooth range (10 metres). If you want to pair a new device, double press the power button to enable the Bluetooth pairing mode.

3. Enable the Bluetooth feature on your device and select "REAL BLUE NC 3" from the list of available devices. The LED will light up in blue for 3 seconds if the pairing was successful. You will also hear a system sound.

[Notice] Bluetooth mode only works if no connection cable is connected to the AUX In port (4). As soon as the connection cable is connected, Bluetooth mode will be disabled. The headphones save the last 7 paired devices and automatically connect to them if the devices are within Bluetooth range (10 m). To delete the device list, press and hold the power button (1) for 8 seconds while the headphones are switched off until the LED flashes blue twice.

Information on the wireless Bluetooth connection

• The headphones are compatible with Bluetooth 5.3.
• If your audio source supports high-resolution audio encoding methods SBC, AptX, and AAC, the music will automatically be played in high audio quality.
• The paired devices immediately establish the Bluetooth wireless connection after switching on and are ready for use.

When the headphones are switched on, they automatically attempt to connect to the last connected Bluetooth device.

• You can access this mode by short pressing the ANC/Transparency button (7) twice.
• The ANC/Transparency LED (6) lights up in yellow.

Using the headphones to make phone calls

The Teufel REAL BLUE NC 3 has a built-in microphone. If the headphones are connected to your smartphone via Bluetooth, they can be used as a headset for making phone calls. Music playback will be interrupted when there is an incoming call and will resume when the call ends.

Using the voice assistant

The Teufel REAL BLUE NC 3 has a built-in microphone. If the headphones are connected to your smartphone via Bluetooth, press and hold the centre of the joystick (5) for 1.5 seconds to enable the voice assistant (when not making a phone call).

Reset and Audio Cable Usage

Reset

If you want to reset your headphones to the default settings, press and hold the power button (1) and the ANC/Transparency button (7) simultaneously for 4 seconds.

The status LED (2) will alternate flashing in red and blue during the reset and will fade out when the reset is completed. Please note that the Bluetooth device list will be cleared and personal settings made in the Teufel Headphones App will be deleted.

Use the audio cable

Connecting the audio cable

[Diagram illustrating the connection of the audio cable. The 3.5mm jack plugs are shown connecting to the headphones' AUX In port and an audio source.]

1. The enclosed audio cable has two 3.5 mm jack plugs. Insert the notched 3.5 mm jack plug into the AUX In port (4) of the headphones. Make sure that the cable remote control is closer to the headphones than to your audio system or smartphone.
2. Connect the other jack plug of the audio cable to the 3.5 mm jack of your audio system or smartphone.
3. To disconnect the audio cable from the headphones, carefully remove the jack plug from the 3.5 mm jack of the AUX In port.

[Notice] The Bluetooth function will be automatically cancelled as soon as the headphones are connected using the 3.5 mm jack plug.

Using the remote control

The remote control (8) on the audio cable has a built-in microphone, a control button for making phone calls and for controlling music playback.

Charging

To check the current battery level of your headphones, short press the power button (1).

The status LED (2) lights up and indicates the current battery level for 10 seconds.

The LED colour lights up in white at 60–100% and in yellow at 21–59%. If the status LED (2) flashes red repeatedly, the battery level is at 1-20% and the headphones need to be recharged. You will also hear a system sound when the battery level is low.

Connect the enclosed USB-C charging cable to the USB-C port (3) of the headphones and the other end of the USB-C charging cable to a USB port on the PC or a USB charger.

Once the battery is fully charged, unplug the USB-C charging cable from the USB-C port of the headphones. The LED will turn off.

Maintenance and Care

Cleaning

Clean the ear cushions and the headband with a soft, dry cloth. Never use aggressive cleaning agents, as these can damage the sensitive surfaces.

Handling

• Put the headphones on so that both ears are well covered.
• Adjust the length of the headband to your head size if necessary.

Storage

Fold up the headphones for space-saving storage.

[Diagram showing how to fold the headphones for storage.]

Use the enclosed bag to store and transport the headphones and accessories.

Store the headphones in a clean and dry place at room temperature and out of the reach of children.

Changing the ear cushions

1. Hold the ear cup firmly with one hand while changing it, as the swivel joint could break if too much pressure is applied.
2. Start at the top of the cushion and then go between the cushion and the headset, for example, with the thumb nail of your thumb. Please be careful not to make any twisting movements, as the protrusion inside the headset could possibly be damaged.
3. When fitting a new cushion, make sure it is in the correct position. The notch in the cushion and the protrusion on the headphones serve as positioning aids. Simply start there and then carefully clip in the complete cushion.

[Diagram illustrating the process of changing the ear cushions, showing how to grip the ear cup and detach/attach the cushion.]

[Notice] The headphones, batteries, and ear cushions must be disposed of at the end of their service life at separate collection points specified by the local authorities. This ensures that WEEE waste is recycled and treated in a way that conserves valuable materials and protects human health and the environment.
