Adaptive Noise Cancelling Headphones
Adaptive technology adjusts the strength of cancellation based on the level and type of the surrounding noise. Basically noise cancellation is high (stronger) when background noise is loud, and the opposite – the amount of noise cancellation is small when background noise is low.
Additionally, can active noise-cancelling cause headaches?
Of the 34 who said they had used noise-cancelling headphones, 18 (52 percent) said they had experienced some level of discomfort—which they described as a pain in their ears, a feeling that their ears needed to pop, dizziness, headaches, or nausea.

What is Active Noise Cancellation?

Which type of noise cancellation is best?
Feedforward Active Noise Cancellation –
Here, the mic is outside the ear cup and hears the outside noise before you can. It then processes the intrusive noise to create the anti-noise waves to cancel or neutralise the former so you can enjoy the sound.
