3. What your headphones can do

Your Jabra headphones let you do all this:

Listen to music with or without the noise cancellation feature

Enjoy a quiet environment thanks to the noise cancellation feature

How does Active Noise Cancellation work?

Active Noise Cancelling headphones are comprised of three parts: the microphone, which measures the ambient noise, the speaker, and between the two, the noise cancellation electronics which measures noise and generates the ‘anti-noise’ response.

Anti-noise is an inverted copy of the noise itself. When anti-noise is combined with the original sound disturbance it results in a lower level of noise perceived by our ears.
