Hi TiagoZerbatto,
Thank you for reaching Microsoft Community. Apologies for the inconvenience this has caused you.
Kindly try to perform a hardware reset on the headphones then see if the same issue with the ambient noise persists. Follow these steps below: (Set up Microsoft Modern Wireless Headset - Microsoft Support)
Before you start, make sure your headset is sufficiently charged.
- Plug in your headset using the USB cable.
- Slide the Power button on to turn on your headset.
- Press and hold the Answer/end call button for more than 10 seconds. While still holding down the Answer/end call button, press and release the Bluetooth pairing button.
You'll hear a message saying your headset is on and how much battery you have left. - Release the Answer/end call button.
