Take the next step in truly wireless noise-canceling performance and exceptional sound quality. The new Integrated Processor V1 delivers unmatched performance while using even less power. Adding in drastically enhanced call quality, IPX4 water resistance, and up to 24 hours of battery life with wireless charging, the Sony WF1000XM4B Truly Wireless Earbuds are unlike any other before them. They feature intuitive touch control settings for example, tap on the left earbud to change from Noise Canceling to Ambient Sound and long tap for Quick Attention, or double tap on the right to skip to the next track. What's more, you can assign your own functions to each earbud using the Headphones Connect app. Get hands-free help. Just say "Hey Google" or "Alexa" to activate your preferred voice assistant. You can manage your day and even control your headphones with commands like "Turn off noise cancellation". As soon as you speak to someone, Speak-to-Chat automatically pauses the music and lets in ambient sound so you can conduct a conversation, handy if you want to keep your headphones on, or if your hands are full. And once your chat is over, your music starts playing again automatically. Speak-to-Chat uses an acceleration sensor to recognize and react to your voice. It is based on Precise Voice Pickup Technology, which combines four microphones and sensors with advanced audio signal processing. Beamforming microphones are calibrated to only pick up sounds from your mouth. With an improved signal-to-noise ratio theyll catch every word, even when theres a lot of noise around you.
