I already have the best ear muffers money can buy in my country, and it is still not enough. I cannot use ear plugs because of my tinnitus hearing aids. I'm in an area with a lot of noise and this is not going to change. The main issueI face is loud music. Could a noise canceling headphone provide some solace?

Using iem with ANC on the street

Hello!

I'd appreciate knowing how is it to go out on the street using an iem with ANC. Especially when you are on a sidewalk next to a heavy-traffic street or when you are on the subway for example. Does the ANC eliminate completely those types of loud sounds? Or they are still present but just not on the same level?
I ask this because I use IEM with foam ear tips but with no ANC. I feel that the foam ear tips normally makes a good seal and isolate conversations next to me or other sounds in my house. But when I go to the street in those places I mentioned the sounds are still somewhat present, although not at the same level as the music I hear. So I was thinking if I could achieve more isolation using for example a ANC iem.
Any insight would be much appreciated thank you!

One of the greatest sources of stress in my life right now is noise. This is consistent with the (presently unconfirmed) hypothesis that I'm probably on the spectrum.

I live in a very noisy neighborhood, with many sources of loud music several days a week. I use a regular headphone to try to isolate myself, but they're not always effective. I was thinking of purchasing a noise canceling headphone (NCH). I'd listen mostly to podcasts and white noise. Hence the title question: can these headphones cancel variable non-regular noises like loud music around me? And to what degree?

Product recommendations are welcomed, with a focus on great noise canceling. I have a preference for over the ear headphones, but that's not a hard requirement. Other than that I don't have any requirements.

Thanks!
