Using the headphones

Information on the rechargeable battery and the charging process

The headphones have a built-in rechargeable battery. A complete charging cycle takes approx. 2 hours. The charging time may vary depending on the power source used and the ambient temperature. Before using the headphones for the first time, charge the rechargeable battery for a complete charging cycle without interruption. When the headphones are being charged, the LED display lights up (> 9). Once the headphones are fully charged, the LEDs flash white for approx 5 minutes and then go off.

When the battery charge drops to a low level, the voice prompt “Recharge headset” asks you to recharge the headphones. If the headphones are not charged, the voice prompt will be repeated every 10 minutes until the headphones switch off. Sonova Consumer Hearing recommends using the supplied USB cable and a compatible standard USB power supply for charging the headphones. While the headphones are being charged, you can still listen to music or make phone calls. In this case, however, the charging time may be longer. 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: > 43.

Charging the headphones’ rechargeable battery

1. Make sure that the charging socket is free from moisture and contamination. Connect the USB-C connector of the charging cable to the USB socket of the headphones.
2. Connect the USB-A connector to a corresponding socket of a USB power source (to be ordered separately). Make sure that the USB power source is connected to the power supply system. The charging process of the headphones begins. The LED display indicates the charge status.

If the LED display does not light up:

• Clean the charging socket (> 38).
• Charge the rechargeable battery until the LED display lights up again (at least 30 minutes) (> 14). If the rechargeable battery is completely discharged, it may take several minutes for the LED display to indicate the charging process.

Connecting the headphones to a Bluetooth device

To be able to use the Bluetooth connection, you must register both devices (headphones and e.g. smartphone) once. This process is called pairing. If the operation differs from the steps mentioned, also refer to the instruction manual of the Bluetooth device you are using.

Information on the Bluetooth wireless connection

The headphones are compliant 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™ Adaptive (aptX™, aptX™ Low Latency) 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. On switch-on, the headphones automatically try to connect to the last two connected Bluetooth devices.

The headphones can save the connection profiles of up to six Bluetooth devices with which they have been paired. Audio playback is only possible from one device at a time. If you pair the headphones with the seventh 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 headphones again.

Pairing the headphones with a Bluetooth device

1. Switch the headphones off and place them close to the Bluetooth device (max. 20 cm).
2. Press the multi-function button for 5 seconds. The headphones are switched on, and you hear a sound signal. The LEDs light up white 3x. The headphones switch to pairing mode. The LEDs light up as a white continuous sequence, and a melody can be heard.
3. Activate Bluetooth on your Bluetooth device.
4. Via the menu of your Bluetooth device, start the search for new Bluetooth devices. All active Bluetooth devices in the proximity of your Bluetooth device are displayed.
5. From the list of found Bluetooth devices, select “MOMENTUM 4”. If necessary, enter the default pin code “0000”.
6. If pairing was successful, you hear the voice prompts “Pairing successful” and “Connected” one after the other. The LED flashes white 3x.

Switching the connection to paired Bluetooth devices/“Connections.”

To selectively switch the audio connection to paired Bluetooth devices using the “Connections” function, you require the Smart Control app (> 19).

• In the Smart Control app, tap “Connections”. The list of Bluetooth devices paired with the headphones appears.
•  From the list, select the paired device to which you want to connect the headphones. Make sure that the desired device is switched on and Bluetooth is activated. The Bluetooth audio connection between the desired Bluetooth device and the headphones is established. The app connection between the device with the Smart Control app installed and the headphones remains active (only Bluetooth Low Energy for communication between the app and headphones; the device name is highlighted in bold).

Disconnecting the headphones from a Bluetooth device

• Via the menu of your Bluetooth device, disconnect the connection to the headphones. The headphones are disconnected from the Bluetooth device. You hear the voice prompt “No connection”. The headphones switch to standby mode.

Installing the Smart Control app

To make full use of all the settings and functions of the headphones, you need to have the free Sennheiser Smart Control app installed on your smartphone. Download the app from the Apple App Store or Google Play and install it on your smartphone. Alternatively, you can use your smartphone to scan the following QR code or to call up the following Internet site: www.sennheiser-hearing.com/smartcontrol.

• Connect your smartphone to the headphones via Bluetooth (> 15).
• Start the Smart Control app.
• Follow the instructions in the app. The Smart Control app recognizes the headphones and activates all available settings and functions.

Switching the headphones on

Automatic switch-on

• When the headphones are in the supplied carry case: take out the headphones from the carry case. One LED flashes white 3x. The headphones automatically switch on.
• Put on the headphones. You hear a sound signal. If Bluetooth is activated on the headphones and a paired device is available, you hear the voice prompt “Connected”. If Bluetooth is deactivated on the headphones (> 35), you only hear a sound signal. The active noise cancellation ANC may be activated (> 26).

Manual switch-on

• Press the multi-function button for 3 seconds. One LED flashes white 3x. You hear a sound signal. If Bluetooth is activated on the headphones and a paired device is available, the LED lights up white, and you hear the voice prompt “Connected”. If Bluetooth is deactivated on the headphones (> 35), you only hear a sound signal. The active noise cancellation may be activated (> 26).

Switching the headphones off

Automatic switch-off

After taking off the headphones, they automatically switch off after 15 minutes. You can adjust the time span using the Smart Control app (> 19). After being placed in the supplied carry case, the headphones immediately switch off automatically.

Manual switch-off

• Press the multi-function button for 3 seconds. You hear a sound signal. One LED flashes red 3x. The headphones switch off.

Putting the headphones on and adjusting the headband

For good sound quality, the best possible noise cancellation, and the best possible wearing comfort, the headband can be adjusted to properly fit your head.

• Wear the headphones so that the headband runs over the top of your head. The markings for the right side (R) and for the left side (L) can be found on the inside of the ear cups.
• Move the ear cups up or down the headband slider until:
• your ears are comfortably covered by the ear pads,
• you feel even, gentle pressure around your ears,
• A snug fit of the headband on the head is ensured. For optimal sound quality, the ear pads must surround your ears.

Information on active noise cancellation ANC

Due to its closed design, the headphones offer effective passive isolation from ambient noise. In addition, the headphones have an active noise cancellation (ANC) function, which allows you to reduce ambient noise to a minimum. Even when ANC is activated, your headphones’ sound quality is always at its best. You can activate or deactivate ANC when the headphones are connected to your audio source via Bluetooth or via the audio cable/USB cable (provided that the battery is sufficiently charged).

If you want to create a quiet space in a noisy environment, you can simply use the headphones – without connected cables and without Bluetooth devices – as noise protection by using ANC (> 26). With the Smart Control app, you can select different ANC modes that provide the optimal settings for your application/situation.

Notes on active noise cancellation

• Continuous and low-frequency noise, such as motor or fan noise, is particularly well suppressed.
• Speech or high-frequency noise is significantly reduced, but can remain perceptible.
• In very quiet environments, slight noise may occur. In this case, deactivate ANC.
• If an unusual (whistling or beeping) noise occurs, take the headphones off and put them on again. Make sure that the ear cups fit properly around your ears.
• To avoid loud, unusual (whistling or beeping) noise and to ensure proper noise cancellation, do not cover the microphone openings of the active noise cancellation circuitry located on the outside of the ear cups.

Information on the Transparency Mode – Hearing ambient sounds or conversations

With the Transparency Mode activated, you can hear ambient sounds or communicate without having to remove the headphones. This allows you to hear, e.g., announcements in the train or aircraft, or to have short conversations. The Transparency Mode optimally complements the active noise cancellation ANC.

Via the adjustable intensity of the Transparency Mode and the active noise cancellation ANC, you can determine how much ambient noise reaches your ears or whether you want to listen exclusively to your music (ANC at full intensity). If you use the Transparency Mode at full intensity, disturbing sounds, e.g., low-frequency noise such as aircraft noise, are always suppressed so that you can stay relaxed and in touch with your surroundings.

Switching between the active noise cancellation ANC and the Transparency Mode

You can use the gesture control on the touchpad to switch between the active noise cancellation ANC and the Transparency Mode, e.g., if you want to transition from ambient awareness to idle mode as quickly as possible. This function is not available during an active call, see: > 29.

• To switch between the modes, tap the touch pad 2x.

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 headphones, leave the Bluetooth transmission range of the smartphone, the sound quality deteriorates increasingly until you hear the voice prompt “Lost connection” and the connection breaks down completely. If you immediately re-enter the Bluetooth transmission range, the connection is automatically re-established.

Resetting the headphones

If the function of the headphones is disturbed, perform a reset. Individual settings, such as the pairing settings, are not deleted.

• Press the multi-function button for 20 seconds. You hear a short confirmation sound.

Deleting the Bluetooth pairing list of the headphones

You can delete the Bluetooth pairing list using the Smart Control app. Follow the instructions in the app.

Resetting the headphones to the factory default settings

To be able to reset the headphones to the factory default settings, you require the Smart Control app (> 19).

• Switch on the headphones (> 19) and connect them to a Bluetooth device on which the Smart Control app is available.
• Select the “Factory default settings” function in the app settings.
• Follow the instructions in the app.
