Bests & Worsts Reviews from Amazon

* * * PLEASE READ ALL * * * First of all I'm a headphone collector. I have multiple high end examples of open backs, closed backs, several DAC & amp setups and wireless headphones. Note that I have the well regarded Sony 1000x wireless ANC headphones sitting right here to compare with the PX. Now should you buy these B&W PX Wireless ANC (Active Noise Canceling) headphones?..... Maybe, depends on your priorities. 1. Sound Quality Potential: The PX were designed to sound their best with the ANC off. I have to say they sound wonderful with ANC off. They are possibly the BEST sounding wireless headphones on the market (with ANC off). They also have very strong isolation, naturally with their closed-back design and tightly sealing leather ear cups. 2. Active Noise Canceling: The PX have 3 ANC modes: Office, City, Flight. - Office mode is the lightest ANC and sounds pretty great. In the mobile app you can customize whether or not you want to pass-through the voices of people near you. Office mode works great in the office, coffee shop, or at home. I've been using Office mode when ever I'm not in a quiet listening situation. In Office mode the PX blocks out a lot (slight ANC+good seal/isolation) and still sounds better than my Sony 1000x. - City mode and Flight mode are much stronger amounts of ANC and these modes prioritize the noise cancelling over the sound quality. These modes do not sound as good. Sitting here at my desk they sound pretty awful but what would be the point of playing these headphones in FLIGHT mode while not on a plane? ***UPDATE*** I've taken a trip with the PX now. Office mode is perfect for around the airport. The Flight mode is good on the plane. It's not as effective at canceling the plane noise as the QC35 or 1000x but better than over-ear cans without ANC. 3. Wireless Features: I love that the PX turn on automatically when you take them out of your bag and put them on. I love that the PX pause automatically when you take them off (to talk to someone) and resume playing instantly when you put them back on. I also like the actual buttons on the PX for next, back and volume up/down. Comparatively the Sony 1000x and B&O H9 have complex touch/swipe controls that I have found to be a hot mess. BT range is great and battery life is fantastic. 4. Comfort: The Sony 1000x and Bose offerings might be slightly more comfortable for all-day wearing. I do not mind the weight, ear cups or headband of the B&W PX. I also own the B&W P7 and P9 units and can tell you they get more comfortable over time. Conclusions: If your priority is music sound quality in wireless headphones for home, office, library, while also occasionally needing ANC... BUY THESE. If you prioritize noise canceling above all else because you fly all the time, work at the airport, or mow lawns professionally maybe you should buy the Sony 1000x or Bose QuietComfort 35. For me these are what I want in wireless cans and will sell the 1000x.
