I feel a little alone here..... I owned the P7W and loved it. I am always moving my gear around and buying and selling to try to find the perfect “all in one portable.” I’ve tried many sets in this price range including the following: Momentum wireless, momentum 2, beats studio 2, the B&W P7W, B&W PX, Oppo pm-3, Plantronics backbeat sense, Beyerdynamic T51i, beyerdynamic DT770 80 ohm, master dynamic mh40, bang and olufsen wireless not noise canceling...can’t remeber the model, the Bose always gave me headaches from pressure of the NC, and the 1000xm2. can’t think of the rest....there’s been more.
My favorites on sound qaulity alone are the B&W P7W, and the Beyerdynamic DT770 80ohm. I wish beyer would make a wireless version of the dt 770. I think that would fit my perfect idea of a headphone.
One thing I always do to make sure my headphones are accurate is to watch movies on them. If a door shutting doesn’t sound like a door shutting then they are junk to me. It’s easier to forgive a headphone when listening to music, but when I’m watching movies if voices or sound effects are off then I can easily separate the good from the bad.
For now the B&W P7W are my idea of the best wireless headphone available...
