Assuming by "iPhone" you are asking if the headphones work on iPhone the answer is not after 6

Noise camcelling is a commonly misused term. Noise "cancelation" would imply that the headphones had a built in external mictophone to read ambient noises or tones and then would use "anti-noise" to counteract them. These are not noise cancelling. HOWEVER they are great for noise isolation, (the headphones create a seal that physically blocks out external noise)

Q: do they fall out during physical activity?

I think all plugs fall out while exersize, but these hold very good. But still, they will fall down after some time like all the others..
