Venerable audio brand Denon, founded in 1910 and now owned by health-and-audio-device maker Masimo, introduced its first sets of wireless noise-cancelling earbuds with audio personalization Tuesday — Denon PerL and PerL Pro featuring Masimo AAT.

AAT stands for “adaptive acoustic technology,” something Masimo enhanced when it absorbed Australian sound-personalization innovator Nura months ago. Hear that, AirPods Pro 2?

A judge in Washington, D.C., ruled Tuesday that Apple infringes on one of medical device maker Masimo’s patents for light-based pulse oximetry sensor functionality and components used in Apple Watch 6 onward. The sensor measures blood oxygen levels.

Next the U.S. International Trade Commission (ITC) will decide whether to ban imports of Apple Watches that include the sensor, Masimo said.

In a statement, Apple disputed the ruling.
