If you lift one of the ear-cups for a brief chat or hang them around your neck, the music will automatically pause, then resume when you're ready to start listening again. The PX are instinctively in tune with the listener, and a dream to use. Premium Bowers & Wilkins Sound Quality Bowers & Wilkins are widely renowned for delivering supreme sound quality. Angled drive units within the ear-cups ensure an immersive, expansive sound-scape of lush but powerful bass, and exceptionally detailed mids and trebles. Bluetooth supports aptX HD for 24-bit high resolution streaming, to ensure the best possible wireless connection. And they upscale the digital signal to 768Hz for even further detail enhancement. Adaptive Noise Cancelling With adaptive noise cancelling you can shut out the noisy distractions of the outside world and get beautifully immersed in your music. Ambient sound is effectively blocked without affecting the listening experience. A choice of three modes lets you select the best level of noise cancellation for your situation. 'Flight' blocks out engine noise and minimises cabin sounds, 'City' reduces external noise but keeps you aware of your surroundings, while 'Office' limits background chatter and office noise but tunes into nearby discussions. Switch easily between modes with the PX app on your smart device (available on iOS and Android). Premium Design The PX will keep you immersed in premium Bowers & Wilkins sound quality for 22 hours off a single charge. Their construction is premium too. Lightweight materials and real leather enhance comfort and durability. Ergonomically designed ear-cups provide a superior acoustic seal, and they fold flat for easy storage. This is a beautifully designed and powerfully intuitive audio companion.
