Which headphones have the best noise cancellation (active+passive)?

Question

Headphones

It is necessary to remove the noise from the road (tram + traffic). Price up to 20,000 rubles.

Answer 1

Get Bose .
Only it will be necessary to get used to active noise reduction a little, because it feels like I'm deaf.

Answer 2

Before using noise canceling headphones, but open type (plugs, small cups), look towards completely closed headphones. For example, I use Sennheiser HD 598 - external noise is almost inaudible.
