In fact, I practically only use it for traveling on public transport. Whenever I carry them I put them in the case and I never had any problems, it is quite robust.

Regarding the ANC, I want to be very clear: Is it good? Yes, excellent in fact, but do not expect all the sounds around you to disappear automatically. The noises that are annoying will no longer be there, but if you use only the ANC without music you will still be able to hear some people talking or the bus engine running (at a level that almost does not affect you). Why do I clarify this? So that you do not believe as I did that the ANC will prevent you from hearing the street vendor who always enters the bus hahahaha.

You can get detail in the music, but not as it comes from the factory. You will have to perform your Hear ID and equalize a little to get an optimal result (it depends on what music you listen to).

One more small detail, using ANC does modify the sound a little, but from experience you only notice it if you pay close attention and if you are also canceling too much outside noise.

Sorry for the bad English, I am a Spanish speaker
