How does the High-End Sound Tuning mode lift the audio performance of the MOMENTUM True Wireless 2 to its highest level?
Answer: The High-End Sound Tuning utilizes Digital Signal Processing (DSP) to provide a refined pure audio experience. Combined with the high-quality Bluetooth codecs aptX and AAC, the High-End Sound Tuning lifts the audio performance of the MOMENTUM True Wireless 2 to its highest level. This tuning mode can be activated by the Sennheiser Smart Control app.
- Cleaner Bass: MOMENTUM True Wireless 2 standard audio tuning is more in line with mainstream expectations of bass merging with the mids, making the headphones sound slower and less dynamic for some well recorded music. The High-End Sound Tuning resolves this issue by striking a delicate balance between punchy and impactful bass and clear mids.
- More present upper mids/low treble: The standard tuning is slightly dark and relaxing for less listening fatigue. The High-End Sound Tuning makes voices far more vibrant and life-like.
- Equalization of masking treble peaks: The MOMENTUM True Wireless 2 utilizes Sennheiser’s powerful 7mm dynamic driver, presenting a punchy bass and lowest-in-class distortion. The High-End Sound Tuning prevents unwanted peaks from natural resonances in the ear canal, elevating it to have the cleanest treble reproduction.
Can I use the MOMENTUM True Wireless 2 without the Sennheiser Smart Control app?
Answer: Yes, you can use the MOMENTUM True Wireless 2 without the Sennheiser Smart Control app for music listening, phone calls and voice assistant access. The Smart Control app further enhances this experience by adding several additional personalization options such as adjusting the audio EQ, customizing the touch controls and selecting the voice prompt language. The Smart Control app also enables you to receive the latest firmware updates.
Are the batteries replaceable?

What should I check if I can’t hear anything when using the earbuds?
Answer: Make sure that the earbuds are charged and connected to your Bluetooth device. Check in the Bluetooth settings of your connected device has media and calls connection activated. The left earbud can only be used when the right earbud is also used as the right earbud controls the
Bluetooth transmission. Additionally, make sure the earbuds are inserted into your ears correctly. Increase the volume on your Bluetooth device and on the earbuds by pressing on the right earbud’s touch pad until you hear the voice prompt “Volume max”.
What should I check if I can’t pair the earbuds with my Bluetooth device?
Answer: If Bluetooth pairing does not work, proceed in the following order:

Are there reasons why the earbuds may not recharge as usual?
Answer: Ensure that the charging contacts of the earbuds and the charging case are clean. If charging is still not possible, perform a reset and a factory reset of the earbuds.
How can I adjust the earbuds to a comfortable volume or make them louder?
Answer: For some Android smartphones there is a separate volume control for the Bluetooth headset and for the Android smartphone. Ensure that both volume controls are set to max. To increase volume, tap and hold the touchpad of the right earbud until you hear the voice prompt “Volume max”. Now increase the smartphone’s volume to maximum volume.
For smartphones that feature “absolute volume control” such as the Apple iPhone, there is only one volume control available, so you can either use the smartphone’s or MOMENTUM True Wireless 2 volume control. With a few smartphones “absolute volume control” is not available by default but can be activated within the development options.
Furthermore, you might not be able to perceive the full volume of the MOMENTUM True Wireless 2 because the earphones currently do not fit correctly. Please use the appropriate size of ear adapters so they fit snugly in your ear canal and completely seal your ears. For best results, follow the guidance in the quick guide on how best to place the earbuds into your ears.
My ANC (Active Noise Cancellation) performance seems to have only limited effect?
Answer: MOMENTUM True Wireless 2 blocks out ambient noise thanks to its ANC (Active Noise Cancellation) feature which works in combination with its excellent passive noise attenuation and perfect fit in the ear canal. The MOMENTUM True Wireless 2 has integrated a single-mic feed-forward ANC system per earbud side. This technology enables ANC without negative impact on sound performance (i.e. no additional noise floor is introduced by the ANC system), nor discomfort (i.e. no ear pressure is introduced by ANC system). In case you experience only limited ANC performance, consider
that ANC technology can only reduce ambient noise in low frequency range <1 kHz, e.g. engine sounds. The MOMENTUM True Wireless 2’s excellent passive noise isolation additionally reduced significantly ambient noise in higher frequency ranges.
To achieve best possible sound isolation and ANC performance, it is important to choose the ear adapters that best fits your ears.
During the OTA firmware update an error occurred?
Answer: In case you experience any issues during the OTA firmware update of your MOMENTUM True Wireless 2, please follow the following steps:
- Insert both earbuds into the charging case for at least 10 seconds
- Take the earbuds out of the charging case and connect them again to the Sennheiser Smart Control app
- Repeat the OTA FW update or follow the instruction of the app
Why do I see only one battery level for both earbuds in the Sennheiser Smart Control app?
Answer: The battery level indicator always shows the remaining battery life of the earbud side with less power.
Examples:
- If left earbud has 50% battery level and right earbud has 80% battery level, it indicates 50% battery level.
- If left earbud has 90% battery level and right earbud has 20% battery level, it indicates 20% battery level.
- If only right earbud is in use and left earbud remains in the charging case, it indicates the right earbud battery level.
When watching video or gaming on my device is there a recommended way to ensure the sound is in sync with the visuals?
Answer: Perfect synchronization of sound and image is dependent on the Bluetooth technology being used by your Bluetooth device. For best results make sure you are using a Bluetooth device which fully supports Audio Video Distribution Transport Protocol (AVDTP) 1.3 or higher. Thus, depending on the Bluetooth device or the mobile app the audio/video synchronization experience may vary. It is recommended to use always the latest software for your Bluetooth device or the mobile apps.
How can I ensure the best fit for the earbuds?
Answer: It’s always best to test the supplied ear adapters to find the size that suits you best and delivers the best sound quality. The MOMENTUM True Wireless 2 packaging includes four different ear adapter sizes (XS, S, M, L). Also try to twist the earbuds into your ear as described in the quick guide until you find a comfortable position.
Why is it vital to stay in my device’s range to prevent sound drop-outs?
Answer: Make sure that the earbuds are within the transmission range of the Bluetooth device. Since the right earbud establishes the connection to the smartphone, the transmission can be more reliable when your Bluetooth device is placed on the right side of your body.
What should I consider if I have issues connecting my smartphone with the Smart Control app?
Answer: A very small number of smartphone models may have issues connecting the Smart Control app to the MOMENTUM True Wireless 2. Future app and firmware updates will improve on potential limitations of this nature.
You may try to turn off and turn on the Bluetooth function on your smartphone to reset the Bluetooth module or reboot the smartphone.
You may also try the following: Go to the smartphone’s security and location settings and turn “use location” off and on again, even if the location service is already turned on. This is because some Android models require that the location service is activated when using Bluetooth Low Energy connection, even when the location information is not used. Sennheiser does not use or store location information of the user for other reasons.
You may try to perform a factory reset of the MOMENTUM True Wireless 2. Disconnect the MOMENTUM True Wireless 2 after the factory reset, i.e. remove entries MOMENTUM TW 2 (and LE-MOMENTUM TW 2 if available) in the Bluetooth settings of your smartphone and pair MOMENTUM True Wireless 2 again.
How do I ensure my voice is picked up clearly during phone calls?
Answer: If you find that your voice can’t be heard well by the other party on a phone call, you may wish to check the following: During phone calls, ensure that the earbuds are inserted corrected into the ear-canal and then rotate them slightly. Ideally rotate the earbud so that the Sennheiser logo is in a horizontal position as this ensures the correct beamforming angle for voice pickup. Please also check that the microphone opening is not blocked by the ear itself. Additionally, wind may sometimes impact the quality of the phone call.
