As far as noise reduction in headphones is concerned, Bowers & Wilkins did not find anything so far. With the PX, this changes. With the new OnEar headphones, B & W is relying on the tried and tested design, which has been presented in various models in recent years and has been developed step by step. The PX seems the next step in this evolution.
The biggest question, of course, is: How well does noise reduction work with OnEar design? Libratone is pursuing a similar concept with the Q Adapt – quite recently also tailored to the new pixel smartphone from Google. As a rule, however, manufacturers have opted for a closed-loop design for noise canceling. At the PX, B & W implements three different levels of noise reduction, or defines three scenarios for which headphones are optimized: aircraft, road and office. These preferences can be applied and changed in an app. When the noise reduction in wireless mode is activated, the PX should last 22 hours without an ANC being 29. With audio cables, the ambient noise will be turned off for 33 hours. If you do not use the cable for this feature, the headphones have to be plugged into the socket after 50 hours. B & W installed a plug in one of the earcups for this purpose in the USB type C format.
Bluetooth 4.1 with aptX HD is also supported. Thus, music is amplified to 768 kHz: for better sound. The PX is priced at the upper end of the scale: 399 euros. Available is the new headphones in space gray and gold.
