There's another post about noise cancelling and ANC(Active Noise Cancelling) headphones like the Bose QC brand. ANC headphones only cut background noise, you can still hear voices such as people yelling at the tele at their sports.
I want to ask about tools/techniques to completely remove noise. When I am studying I am annoyed/triggered by talking, phone noises, and everything. I need a way to suppress all of that. I've tried simple earplugs and have some basic ear defenders but a lot f noise still leaks through, are there any better options?
