Bowers & Wilkins Say….
PX headphones are high performance over-ear units that provide the highest quality personal audio experience combined with the convenience of wireless operation and the serenity of noise-cancellation
PX headphones can play music streamed wirelessly from your mobile phone, tablet or computer via Bluetooth, or conventionally connected by a jack cable to a suitable headphone output. PX headphones can also play audio via a USB connection from a computer, and can be used for wireless telephony.
PX headphone Real World Listening features include Environment Filter and Voice Pass-through. Environment Filter noise-cancellation is optional and can be simply enabled or disabled via a button on the headphones. The Voice Pass-through feature enables external sounds, such as conversation or safety announcements, to be heard clearly without any need to remove the headphones. Environment Filter and Voice Pass-through are enabled via the Headphone iOS and Android app available. The app also enables certain headphone characteristics to be adjusted.
PX headphones incorporate a rechargeable battery pack. When fully charged and depending on the degree of Bluetooth, Environment Filter and Voice Pass-through use, the battery pack can provide up to 22 hours use at average volume levels.
