If the noise cancelling performance of your Space One Pro headphones fails to meet your expectations, here are a few steps you can take to improve your experience.

1. Make sure you wear the headphones correctly, and that the left ear cup is on your left ear and the right one is on your right ear.

2. Adjust the headband to ensure the ear cups fully cover your ears. It improves the seal and active noise cancellation (ANC) performance. You're also welcome to send us a photo of yourself wearing the headphones so we can help verify if there's leakage between the ear cups and your ears.

3. Check the ANC level in the app. Higher levels mean better noise cancellation.

It's worth noting that ANC primarily targets low-frequency noise like human voices between 50 and 1.5kHz. It's less effective against high-frequency noise.

By following these steps, you should be able to improve the noise cancelling performance of your Space One Pro headphones.
