Duncan Bosworth, Vice President, Product Line Management, Consumer Business Unit at Analog Devices said, “ADI’s power supply solution offers the lowest power consumption by far for this type of technology. And, the overall playback path offers the lowest power implementation. The combination enabled Bowers & Wilkins to develop a brand new noise-canceling headphone platform with multiple levels of ANC, some of the longest playtime available, and all while further improving the Bowers & Wilkins sound all music and movie lovers can appreciate.
“Our PX5 adaptive noise-canceling headphones offer 25 hours of playtime on one battery charge. And the PX7 headphones offer 30 hours of playtime,” said Ron Vitale, Sr. Director, Headphone Product and Portfolio Management, Bower & Wilkins. “What stands out here is our practical ability to hit these performance levels at extremely low power. It’s our mixed-signal and domain knowledge that lets us be so efficient,” said Duncan Bosworth.
Rajeev Morajkar, ADI said, “The underlying digital technology opens the door to the sheer number of features and capabilities this type of noise-canceling and noise filtering can achieve. Not just the quintessential noise-canceling “‘drowning stuff out’” other competitors can produce, but the ability to customize sound extensively.” For example, the system can “listen in” and try to figure out if you in a meeting room, in an airplane, or walking around a mall and adjust the parameters. As both a listener or manufacturer, it allows you to adjust how aggressively it does that and let voices through.
