Sony WH-1000XM4 Wireless Noise Cancelling Over-Ear Headphones

Discover how the WH-1000XM4 headphones blend Sony's most advanced noise cancelling with exceptional sound quality and a range of smart features for an unrivaled listening experience.

Industry-leading noise cancelation

Industry-leading noise cancellation technology means you hear every word, note, and tune with incredible clarity, no matter your environment. These noise cancelling headphones feature additional microphones that assist in isolating sound for a reduction of even more high and mid-frequency sounds.

The technology that makes it happen

Dual noise sensor technology, featuring two microphones on each earcup, captures ambient noise and passes the data to the HD Noise Cancelling Processor QN1. Using a new algorithm, the HD Noise Cancelling Processor QN1 then applies noise cancelling 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.

Optimizing noise cancelling

To maximize noise cancelling performance, the WH-1000XM4 headphones incorporate two technologies: Personal Noise Cancelling Optimizer, designed specifically for you, and Atmospheric Pressure Optimizing, designed specifically for air travel.

Ambient Sound Control

Adjust ambient sound with the Sony | Headphones Connect app to cancel noise while still allowing essential sounds, like overhead announcements, through when you're listening on the move.

Wireless freedom, premium sound

LDAC transmits approximately three times more data (at the maximum transfer rate of 990 kbps) than conventional BLUETOOTH® audio, allowing you to enjoy High-Resolution Audio content in exceptional quality, as close as possible to that of a dedicated wired connection.

Sound you can believe in

A built-in analog amplifier integrated in the HD Noise Cancelling Processor QN1 realizes an unmatched 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 perfect for handling heavy beats and can reproduce a full range of frequencies up to 40 kHz.

Real-time restoration of all your compressed files

Using Edge-AI (Artificial Intelligence) co-developed with Sony Music Studios Tokyo, 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.

Smart listening technology to enhance your listening

The WH-1000XM4 headphones use an array of smart technologies to create a seamless, hands-free listening experience. For example, simply start speaking to automatically pause your music in Speak-to-Chat, or enjoy adaptive playback thanks to the proximity sensor and two acceleration sensors that detect whether your headphones are being worn or not.

For everyday convenience, just Speak-to-Chat

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 your headphones and advanced audio signal processing to recognize and react to your voice. And once your chat is over, your music starts playing again automatically.

Adaptive Sound Control automatically adjusts to whatever you do

Adaptive Sound Control is a smart function that senses where you are and what you're doing, then adjusts ambient sound settings for the ideal listening experience.

Headphones that react to you

Proximity sensor and two acceleration sensors in your headphones can detect whether you're wearing them or not, then adapt playback accordingly to help save battery power.

Wear all day in total comfort

WH-1000XM4 headphones blend sophisticated style with exceptional comfort. Super-soft, pressure-relieving earpads in foamed urethane evenly distribute pressure and increase ear/pad contact for a stable fit. And with a lighter-weight design, you'll barely notice you're wearing them.

All day power and quick charging

With a huge 30 hours of battery life, you'll have enough power even for long trips. And if you need to top up in a hurry, you can get 5 hours' worth of charge after just 10 minutes with the optional AC adapter.

Effortless operation

From controlling your music to accessing your voice assistant or making hands-free calls—with the WH-1000XM4, it couldn't be easier.



iFi Audio Go blu Portable Bluetooth DAC/Headphone Amp

Super light. Super sound.

iFi Audio's new GO blu, portable HD DAC/amp, is diminutive enough to take with you wherever you go! It gives you the best sound from wired but the convenience of wireless as you no longer need to have a cable connection to your smartphone.

Whether you're exercising at the gym with your Apple watch clocking your every step or catching up on your MacBook at your favorite coffee shop, the GO blu is the perfect companion.

It pairs wirelessly with your source device via Bluetooth with no need to worry about whether you’ve got the right cable for your Android or Apple device. Just pair … and GO!

Superior sound, unbound.

Wireless headphones or earphones of any kind integrate Bluetooth processing, D/A conversion, and amplification onto one, standard 'off the shelf' chip. There is a ceiling to the sound quality that can be achieved.

Pair the GO blu to your Apple/Android. Connect your favorite corded headphones to the GO blu and then tuck it away –  it’s so petite it will slip into your running gear or suit pocket. It’s also gorgeous enough to show off by leaving it on the table at your favorite coffee shop!

Go blu. Go beyond.

With its lightweight, soft-touch polymer enclosure (great for Bluetooth reception, unlike signal-blocking metal), copper-colored trim, and ChronoDial watch crown-style control, the GO blu is a pleasure to use wherever you go.

iFi has even incorporated a high-quality chip-based (CMOS-MEMS) microphone, enabling hands-free calls, voice chat for gaming, and access to voice assistants such as Apple Siri and Google Assistant.

HD Bluetooth 5.1

The way iFi implements Bluetooth is anything but 'run of the mill' and despite its diminutive size, the GO blu is no exception.

The use of Qualcomm’s latest four-core QCC5100 Bluetooth processing chip ensures that every current high-definition Bluetooth audio format is supported.
