Noise pollution hurts the heart

Those who are living in the noisy environments, have you tried the recent noise cancelling earphones/headphones? Do you prefer noise cancelling or adding white noise over long period of use?

Also I'm looking for noise cancellation algorithms which can add noise cancellation to any generic TWS earphones by processing through smartphone[1]. Google has added audio amplification for any TWS earphones through android as an accessibility feature, but not the noise cancellation; Is it because the latency matters for the latter more?

[1]I've added the link to it on my profile.

Noise cancelling, in order to work really well, requires extremely fast processing and microphones that are directly on the ears. And then you need earphones with very well-defined frequency characteristics - which would make any approach with generic earphones very difficult. And not only that, the exact distance between earphones and ear matters a lot - that's why high-end ANC headphones like the Sony ones include a calibration routine.

Noise cancelling doesn't do much for impact noises which seem to annoy people more.
