My MINT condition and 3 week old PSB M4U 2 portable headphones with noise cancelling functionality. I have far too many headphones and with my recent purchase of the Sennheiser Momentum's I think I'm good on that front.
They are the black headphones and again, I would rate them 10/10. They work very well with the Noise Cancelling Circuitry on, but work slightly better without the NC on. So they are very versatile...on a flight, the NC really helps and while around the house, you can turn it off and still enjoy a very neutral/natural headphone.
I wrote a comparative review of several portable headphones that I've owned here and the PSB's scored very highly and are the most versatile headphones of the bunch due to the noise cancellation + ability to not require this functionality when in a quiet environment:
Price: $300 + shipping (Canada / US ONLY).
Absolutely everything that came with them!
Please review my feedback and buy with complete confidence.
