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. |
