Sennheiser PXC 550-II Overview
Designed for all-day use, the PXC 550-II Wireless Active Noise-Canceling Over-Ear Headphones from Sennheiser provide you with up to 30 hours of battery life, padded earcups and headband, and easy access to your smartphone. The PXC 550-II headphones have an integrated voice assistant button that connects you to your phone's digital assistant, such as Google Assistant, Siri, or Alexa. Once connected, a beamforming 3-microphone array helps to focus onto your voice for clearer commands, questions, and hands-free conversations.

The Smart Control app also features a built-in equalizer to optimize sound quality for your audio content.
