FAQs
Are these earbuds suitable for intense workouts or running?
Yes, with their IPX4 splash resistance, they can handle sweat and light rain. The lightweight, ergonomic design is also intended to provide a comfortable and secure fit during movement.
How do I know if the earbuds are fully charged?
The charging case typically has LED indicators that show the charge status of both the case and the earbuds. Refer to the specific LED patterns described in your product's quick start guide for detailed information.
Can I use just one earbud at a time?
Yes, you can typically use either the left or right earbud independently for calls or mono listening, while the other remains in the charging case.
Do these earbuds have active noise cancellation (ANC)?
No, these earbuds feature an 'open-ear' design, which prioritizes situational awareness rather than active noise cancellation. They are designed to let you hear your surroundings while enjoying your audio.
What is the range for Bluetooth connectivity?
The typical Bluetooth range for these earbuds is up to 10 meters (33 feet) in an open environment, though this can be affected by obstacles and interference.
How do I clean the ear tips?
Gently wipe the ear tips with a soft, slightly damp cloth. Ensure they are completely dry before placing them back on the earbuds or in the charging case.
Is there a companion app for these earbuds?
Info needed: Please check the product packaging or Sennheiser's official website for information on a dedicated companion app for additional features and customization.
Troubleshooting
Earbuds won't turn on or charge.
Ensure both the charging case and earbuds are fully charged. Connect the USB-C cable to the case and a power source. Check the charging indicator lights. If issues persist, try a different charging cable or power adapter.
Cannot pair the earbuds with my device.
Make sure the earbuds are in pairing mode (flashing LED). Turn off Bluetooth on other nearby devices that might be trying to connect. Forget the earbuds from your device's Bluetooth history and try pairing again. Ensure the earbuds are sufficiently charged.
Only one earbud is playing audio.
Place both earbuds back into the charging case, close it for a few seconds, then open it again. This often re-syncs them. Ensure both earbuds are clean and have proper contact with the charging pins. Check your device's audio balance settings.
Poor sound quality or intermittent connection.
Ensure there are no physical obstructions between your device and the earbuds. Move closer to your device. Avoid strong Wi-Fi or other Bluetooth interference. Restart your device and the earbuds (by placing them in the case and taking them out).
Touch controls are unresponsive.
Ensure your fingers are clean and dry when using the touch controls. Try resetting the earbuds by placing them in the charging case and closing it for 10 seconds. If custom controls were set, check the Sennheiser app (if applicable) for settings.
