Speak-to-Chat
Listening to music or podcasts with ANC turned on can offer you a quiet and personal experience in public, but what if you need to have a quick conversation? Without the need of switching modes and adjusting volume levels, Speak-to-Chat does it all automatically. All you have to do is talk. Built-in microphones detect that you’re speaking and automatically let ambient sound in and lowers playback volume. When you’re done with your conversation, the earbuds can detect this, too, reversing the volume and ANC changes back to where they were.
Precise Voice Pickup
When making hands-free calls, being heard and hearing others is essential but difficult when out on the street or in a noisy area. To fix this, Sony incorporates beamforming microphones and a bone conduction sensor. The mics focus their pickup pattern directly at your voice, while the sensor picks up the bone vibrations made in your mouth as you talk. This helps to ensure your voice is all that your listeners hear. When it comes to hearing others, you can activate noise cancellation during a mobile call to block surrounding audio.
Adaptive Sound Control
When enabled, the earbuds can learn the locations you frequently visit and how you listen at each location. Then when you revisit those locations, it can automatically adjust your audio as needed.
Long Battery Life
On a full charge, the earbuds can run for up to 8 hours in ANC mode. A charging case is included that features its own battery for an additional 16 hours of power. Simply place your earbuds inside and close the case to begin recharging them.
Quick Charge
In a rush? A quick 5-minute recharge in the case gives the earbuds up to 1 hour of playback time.
Google & Swift Pairing
Say goodbye to complex and annoying pairing processes with Google Fast Pair and Swift Pair. Google Fast Pair immediately pairs the earbuds to a compatible nearby Android device when the case is opened. A single tap on the notification is all you need to do in order to finalize the pairing process. Swift Pair helps you pair the earbuds to Windows 10 laptops, desktops, and tablets, offering you pop-up guidance through the process.
High-Quality Audio
In addition to support for Hi-Res Wireless Audio and the LDAC codec, the 6mm drivers can utilize DSEE Extreme, which upscales compressed files in real time for better overall audio reproduction.
Google or Alexa
Need to interact with your mobile device’s digital assistant to get information, manage playback, set reminders, and more? Simply say “Hey Google” or “Alexa” to activate them via voice command.
Find if Lost
If you misplace the earbuds, you can ring them remotely or view their last known location on a map, thanks to Google Fast Pair, which is supported on Android devices.
Auto Pause/Play
The WF-1000XM4 true wireless earbuds can detect when they are in or out of your ears. When taken out, they automatically pause your music, resuming it when the earbuds are placed back in your ears.
