DSEE Extreme Audio Upscaling
No matter where you go, the silver Sony WH-1000XM4 Wireless Noise-Canceling
Over-Ear Headphones deliver pristine sound quality while automatically adjusting
ambient sound according to your activity and registered locations, leaving your
hands and mind free from the hassle of changing settings just to hear what you
want to hear.Plus, the headphones detect when you’re wearing them and start and
stop your audio for you.
Noise cancellation is accomplished with Sony’s dedicated HD Noise-Canceling QN1
processor and Sense Engine. Sense Engine is designed to automatically adjust the
level of ambient sound based on your environment. If quick communication is
needed, simply speak to chat without audio playing or just cover the right
earcup with your hand to monitor the outside world.
When it comes to what you do hear, the WH-1000XM4 headphones use DSEE Extreme
audio upscaling to perform genre- and instrument-based optimization of the
sound, and they support LDAC, AAC, and SBC codecs. When used with a compatible
source device, LDAC transmits approximately three times more data, up to 990
kb/s, compared to conventional Bluetooth. This is meant to make your
high-resolution audio content sound even better when it’s played back through
the 1.57″ drivers with LCP diaphragms (liquid crystal polymer).
Whether you’re looking for peace and quiet while working from home or you want
an ideal pair of headphones for traveling, Sony crafted the noise-canceling
WH-1000XM4 to be both convenient and comfortable, thanks to the soft,
pressure-relieving earpads and the lightweight design.
High-Tech Noise Cancellation
Dual noise sensor technology, featuring two microphones on each earcup, captures
ambient noise and passes the data to the HD Noise Canceling Processor QN1. Using
a new algorithm, the HD Noise-Canceling Processor QN1 then applies noise
cancellation processing in real time to a range of acoustic environments.
Working together with a new Bluetooth Audio SoC (system on chip), it senses and
adjusts to music and noise signals, as well as acoustic characteristics between
the driver unit and ears, at over 700 times per second.
Adaptive Sound Control
Adaptive Sound Control is a smart function that can learn to recognize locations
you frequently visit, such as your workplace or favorite café, and tailor sound
for the ideal listening experience. In addition, it automatically detects what
you’re up to—walking, waiting or traveling—then adjusts ambient sound settings
to suit the situation.
Optimized Noise Canceling
The WH-1000XM4 headphones incorporate two technologies to maximize
noise-canceling performance. Unique Atmospheric Pressure Optimizing delivers
optimal sound at high altitude, while Personal Noise Cancellation Optimizer
analyzes unique sonic characteristics caused by head size, glasses, and hair,
then tailors sound to you.
A proximity sensor in the WH-1000XM4 headphones can detect whether you’re
wearing them or not, then adapt playback accordingly to help save battery power.
Take off your headphones and the music pauses automatically. Put the headphones
back on and the music automatically resumes.
As soon as you speak to someone, Speak-to-Chat automatically stops the music and
lets in ambient sound so you can conduct a conversation—handy if you want to
keep your headphones on or your hands are full. Based on Precise Voice Pickup
Technology, this smart feature uses five microphones built into the headphones
and advanced audio signal processing to recognize and react to your voice. Once
your chat is over, your music starts playing again automatically.
Regardless of the level of noise-cancelation, the Quick Attention features lets
you quickly hear your environment, whether it’s to hear an emergency
announcement or have a quick conversation. Simply place your hand over the
housing of the right earcup to quiet things down so you can hear.
Sony Headphones Connect App
Adjust ambient sound with the Sony | Headphones Connect app to cancel noise
while still allowing essential sounds, like transport announcements, through
when you’re listening on the move. Ambient Sound Control lets you adjust the
volume of background sound and gives you the option to allow voices alone to be
heard. Meanwhile the Equalizer lets you customize sound levels to suit your
Voice Assistant Integration
When the WH-1000XM4 headphones are paired with your smartphone, you can use them
to access the phone’s voice assistant. Ask it questions and have it perform
tasks just like you would normally do; enjoy entertainment, connect with
friends, get information, listen to music and notifications, set reminders, and
Conversation flows freely with easy, hands-free calling. Leave your phone where
it is, just speak with a double tap. Thanks to Precise Voice Pickup Technology,
which combines five built-in microphones with advanced audio signal processing,
WH-1000XM4 delivers clearer voice quality to the other person on the phone.
A built-in analog amplifier integrated in the HD Noise-Canceling Processor QN1
realizes a pristine signal-to-noise ratio for low distortion and exceptional
sound quality for portable devices. Powerful 1.57″ drivers with liquid crystal
polymer (LCP) diaphragms make the headphones ideal for handling heavy beats, and
they can also reproduce a full range of frequencies up to 40 kHz.
DSEE Extreme Audio Upscaling
Using Edge-AI (Artificial Intelligence) co-developed with Sony Music
Entertainment, DSEE Extreme (Digital Sound Enhancement Engine) upscales
compressed digital music files in real time. Dynamically recognizing
instrumentation, musical genres, and individual elements of each song, such as
vocals or interludes, it restores the high-range sound lost in compression for a
richer, more complete listening experience.
For total convenience, WH-1000XM4 headphones can be paired with two Bluetooth
devices at the same time. When a call comes in, your headphones know which
device is ringing and connect to the right one automatically. You’ll also be
able to quickly and smoothly switch your headphones to either of the two devices
at the touch of a button.
Battery Life: Up to 30 hours of playback with active noise cancellation
Quick Charge: With just 10 minutes of charging via an AC adapter (not included),
