Anyone have a decibel reduction by frequency similar to what is shown here? https://cdn.thewirecutter.com/wp-...=570&dpr=2 In general saying "has ANC" tells you nothing. They should post an expected noise reduction for at least the most effective use case such as an aircraft engine noise. Yes I know its only 20$ but no one wants crap for 20$ even if it is only 20$

I doubt you'll find any kind of decibel rating for these. I tried searching and don't see any.

And I don't generally see dB posted as a spec by the heaphone makers. Even the best like Bose or Sony don't have that kind of dB figure their tech specs.

Rtings.com has 700+ headphone reviews and for ANC they do have isolation testing and include a dB reduction. No Rosewill parts on their lists though.
