PXC 550-II Wireless Active Noise-Canceling Over-Ear Headphones
Product Description
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.
Featuring active noise-canceling technology, the PXC 550-II headphones will filter out ambient noises and sounds that can distract you from your favorite music or an important conversation. The degree of noise cancellation can be customized via the Sennheiser Smart Control app for iOS and Android devices, so you can tone it down or activate Transparent Hearing to get back in touch with your surroundings when needed. The Smart Control app also features a built-in equalizer to optimize sound quality for your audio content.
