Hi guys, so I have never bought noise cancelling headphones before and I am not a music/gaming enthusiast so I do not understand the sound related jargons hence I am having trouble deciding what headphones would be best for me.

My sole requirement is noise cancellation, as I might be moving to hostel soon and need something to be able to study around noisy roommates. So do they really work as advertised, like complete silence, won't be able to hear even if someone was shouting in my ear? Cause that would be ideal.

My budget is 10k but would prefer as cheap as possible. As someone who has been using free earphones my entire life and been content with them, the only justification for spending that much would be if there is complete noise cancellation, like absolute blank. So please give recommendations if such a beast exists as I am a complete noob and don't trust amazon reviews for splurging this much on something like headphones.
