If your Sennheiser Momentum True Wireless left earbud is flashing red, it usually indicates that there is an issue with the earbud or its charging case. Here are a few possible reasons and troubleshooting steps to resolve the problem:
1. Low battery: The flashing red light can indicate a low battery level. Connect the charging case to a power source and verify if the left earbud charges properly. Make sure the earbud's charging pins are clean and properly aligned with the charging case.
2. Connection issue: Check if the left earbud is properly paired and connected to your device. Try disconnecting and reconnecting the earbud from your device's Bluetooth settings.
3. Firmware update required: Sometimes, firmware updates can help resolve issues with wireless earbuds. Ensure that you have the latest firmware version installed. You can check for firmware updates on the Sennheiser website or via the Sennheiser Smart Control app.
4. Factory reset: If the above steps don't work, you can try performing a factory reset on your earbuds. To do this, place both earbuds in the charging case and keep the lid open. Press and hold the button on the bottom of the case for about 20 seconds until the LEDs on both earbuds start flashing four times in alternating colors. Then, re-pair the earbuds with your device.
If none of these troubleshooting steps help, it is recommended to contact Sennheiser customer support for further assistance or consider getting a replacement if your earbuds are still under warranty.

There could be several reasons why your Sennheiser Momentum True Wireless 2 left earbud is not charging. Here are a few troubleshooting steps that you can try:
1. Check the charging case: Ensure that the charging case itself has enough charge by connecting it to a power source and checking if the LED indicators on the case light up. If not, charge the case first before attempting to charge the earbuds.
2. Clean the charging contacts: Sometimes, dirt or debris may accumulate on the charging contacts of both the earbud and the charging case, preventing proper charging. Gently clean the charging contacts on both the earbud and the case with a soft, dry cloth.
3. Reset the earbuds: Try resetting the earbuds by placing them inside the charging case, then pressing and holding the button on the back of the case for about 15 seconds until the LED lights on the case start flashing. This will reset the connection between the earbuds and the case.
4. Check the charging pins: Inspect the charging pins on the left earbud itself to see if they are bent, damaged, or misaligned. If so, try gently realigning them using a small, soft tool like a toothpick or a soft brush.
5. Test with a different charging cable: It's possible that the charging cable you are using is faulty. Try using a different micro USB or USB-C cable to see if the left earbud charges properly with a different cable.
If none of these steps resolve the issue, it may be a malfunction or defect with the left earbud itself. In that case, it is recommended to contact Sennheiser customer support or bring the earbuds to an authorized service center for further assistance.
