Both headphones receive Bluetooth signals with aptX HD and are equipped with individually adjustable, active noise cancelling. When an ear pad is lifted or the entire headset is placed around the neck, music playback stops automatically. The PX7, which weighs 302 grams, uses carbon fiber components and metal as well as genuine leather. The On-ear model is even lighter at 254 grams. The battery life of the top model is 30 hours, slightly longer than that of the PX5 (25 hours). Both are available in "Space Grey", the PX5 additionally in blue and the Px7 in silver. Also new from B&W: two wireless in-ears with silicone neckband and magnetic earplugs: The PI3 (200 Euro) and – available next year – the PI4 with adaptive active noise cancelling.
