Hi, Michael11111111!
Thanks for reaching out to Microsoft Community and posting your inquiry.
Surface Headphones 2 is designed to have active noise cancellation to block out external sound or be able to converse with someone without taking it off. There are several levels of noise cancellation that you can adjust. The information below is from https://support.microsoft.com/help/4469878/
| To | Do this |
|---|---|
| Increase noise cancellation | Turn the dial on the left forward to hear less sound around you. |
| Decrease noise cancellation | Turn the dial on the left backward. When you turn off noise cancellation, outside sound will be amplified. |
You can check the noise cancellation level anytime you're on your Windows 10 PC or mobile device.
On a Windows 10 PC
- Open the Surface Audio app, then select Devices > Surface Headphones.
- On the Home screen, under Noise cancellation, select the noise cancellation level you want.
On an iOS or Android device
- Open the Surface Audio app, make sure it’s connected to your Surface Headphones, and then tap Settings next to Surface Headphones.
- In Device Settings, tap Device info > Noise cancellation, and then tap a new noise cancellation level > Save.
You'll see several levels of noise cancellation in the Surface Audio app. Here's a quick summary of the different levels:
- High. You should hear little or no surrounding sound. This is the maximum noise cancellation level when it's turned on all the way.
- Medium. You'll likely hear loud noise or surrounding voices, but might not hear lower surrounding sounds, such as traffic or sound from a crowd.
- Low. You'll likely hear surrounding sound while listening to music.
- Ambient sound amplified. Noise cancellation is turned off and surrounding sound will be amplified. You'll likely hear surrounding sound while listening to music.
For the specific feature on completely turning this off with pure, unmanipulated sound, I am afraid it is not available. It's a feature that you can suggest. Kindly visit this page to be guided on how to submit your feedback via the Feedback Hup app: https://support.microsoft.com/help/4021566/
If this answers your question, please let our Community know by marking this post as an answer. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.
