1 device. 3 surround sound technologies. 7 I/O connectors. Your all-in-one audio upgrade starts here with Sound Blaster X4.


#TeamSpeakers or #TeamHeadphones? Why not both? The Sound Blaster X4 supports up to 7.1 discrete and virtual audio channels, so you won't have to compromise on the way you enjoy your audio. It is also capable of incredible sound performance—acoustics depth and detail—giving a new lease of life to your headphones and speakers.

Also, it offers not just one, but three different surround sound delivery options. Feel free to discover the unique characteristics of each surround option, try them out on different types of media content, and maybe—relive that favorite piece of yours in a whole new light.

Super X-Fi Headphone Holography

More than just surround technology, Super X-Fi is our award-winning audio technology that captures the listening experience of a high-end multi-speaker system in a professional studio to recreates the same expansive experience in headphones. Without missing out on audio cues and immersive ambient effects, you'll be able to hear the details effortlessly from your headphones—especially spoken dialogs in shows—with natural and lifelike soundstage that's deeply immersive and highly realistic, akin to the movie theaters.

Once set up, simply toggle Super X-Fi on and off using the SXFI button located on the device itself.

Sound Blaster Surround Virtualization

We've been in this space for a long time—more than 30 years to boot. With our renowned Surround Virtualization technology, expect top-tier surround processing made possible through our highly optimized algorithms. To put it simply, these algorithms intelligently identify and enhance the spatial information of the incoming audio, and optimize it for the chosen output format, drawing you to where the action is for a complete and immersive auditory experience.

Dolby Digital Live

For Windows users, the Sound Blaster X4 also features Dolby Digital Live for convenient encoding of any audio sources to multi-channel surround sound in real-time, all while transmitting data using only a single optical cable solution for decoding in a home theater system.

Hear Where They Are

Raise your KDR even further in FPS games with an unfair advantage over your opponents! The Sound Blaster X4 is equipped with both SXFI BATTLE Mode and Scout Mode, so you can choose* the best weapon for your victory.

SXFI Battle Mode

Hear your surroundings in games, just like how you would in real life. SXFI BATTLE Mode is the first and only sound mode that allows you to hear not only the directionality of where the gunshots are coming from, but distance as well—so you can accurately pinpoint your enemies' locations to the millimeter.

Combined with the hyper-realistic Super X-Fi audio and its unprecedented level of audio clarity and depth, gain the extra edge in first-person shooter games that's not just accurate, but immersive too.

Scout Mode

If you've been with us throughout our Sound Blaster journey, you'd know. Scout Mode is one of our trademark sound modes that focuses on detection through enhanced audio cues, highlighting each and every in-game detail that could make or break the game.

Whether it's the sound of your enemies' gun reload or a slight ruffle in the grass, Scout Mode is sure to bring the cues right to your ears. Detect your enemies' slightest movement before even seeing them on screen!

Communicate Smarter with SmartComms Kit

Skip the unnecessary microphone controls, focus on your online meetings, and sound clear in them without the annoying background noise!

Developed to solve common pain points that you face on conference apps, our SmartComms Kit simplifies the way you communicate online via a suite of smart communication features.


Mute and Unmute Yourself Automatically

Get unmuted as you speak and mute your microphone automatically without lifting a finger.

Our VoiceDetect feature controls your mute status by voice detection and frees up your hands—and mind—so you can focus on other important things, like a brainstorming session for the next product launch.


Two-way Noise Cancellation*

Remove unwanted noisy distractions from both ends of a conference call in real time.

NoiseClean-in detects static background noises coming from other users in your voice call, and suppresses the noise while retaining the vocals and spoken dialogs so you can hear them clearly. Put simply, NoiseClean-in cleans up the noises detected from your incoming audio so that their voices are better heard.

NoiseClean-out does the same—but for your own background noise. Now, no one needs to be asked to “go on mute” anymore.

Sound Clearer with CrystalVoice Technology

Improve your voice clarity and be heard clearly with our CrystalVoice technology! The annoying echoes that interfere with your conversations are now a thing of the past with CrystalVoice's Acoustic Echo Cancellation that removes these echoes that goes on a parroting loop.

At the same time, activate Smart Volume inside the software to speak normally without having to shout or whisper—Smart Volume automatically adjusts the loudness of your voice to maintain a consistent volume throughout the conversation, no matter where your microphone (both external and on headset) is angled towards.

There's also the Microphone Equalizer that compensates for your headset's built-in microphone, or your external microphone—whether it is to reduce the harshness of your tonality or to increase the mids for vocal clarity—so you'll sound much clearer and natural to others.

When you're down for some fun, Voice Morph changes your voice into different characters and accents with a list of tuned profiles. Download our Creative app on your Windows PC or Mac to access the CrystalVoice feature!

Connect Everything

You asked, we've listened: The optical-in port is now on the Sound Blaster X4.

With the Sound Blaster X4 and its 7 I/O connectors, it's now much easier to connect multiple audio devices! From external microphones and headsets, to platforms like your PC, Mac, gaming consoles, and even your multi-channel speaker systems—this practically converts your desktop setup into an audio hub.

Speaker Systems:

Breathe new life into your surround speaker system! The line-out ports consisting of Front, Side, Rear, and Center / Sub ports allow you to connect your 2.1, 5.1, and even 7.1 speakers for outstanding audio clarity. Coupled with 7.1 discrete and virtual support, refresh your same old speakers with a new sound identity.

PS4™ (with voice chat), Blu-ray, Set-top boxes, TV, mobile devices:

Chat in-game with your teammates on PS4 and enjoy the Sound Blaster X4's enhanced audio delivery at the same time with the newly added optical-in port! It's also compatible with your Blu-ray players, set-top boxes, and even TV. You can also connect the Sound Blaster X4 to your PS5™ via a HDMI to optical converter (not included) for enhanced audio during your gameplay!

The very same port also acts as a line-in port that will work with your mobile devices or audio players for high-quality audio without fuss.

AV receiver:

Easily connect your Sound Blaster X4 to your AV receiver and your prized surround system using the optical-out port for an enhanced listening experience.

Powering the Sound Blaster X4:

The USB-C port makes it easy for you to power up the device right on your desktop once the connection is made. And when connected to platforms like PC and Mac, the USB-C connection is used for both power and audio, making it super convenient (with less mess) to set up.

External mics and headsets / headphones with mic:

Located on the front of the Sound Blaster X4 for easy access to the microphone and headset ports, simply plug in your preferred choice and get started. Need your team to hear you better? You can further adjust your microphone's gain and volume boost via the Acoustic Engine module of the Creative app. The Sound Blaster X4 is also a headphone amplifier that's capable of driving studio-grade headphones of up to 600Ω with ease.

Direct Mic Mute Button

With a direct microphone mute button on the Sound Blaster X4,  you don't have to scramble to unmute yourself in-app during a conference call, or while in-game. All it takes is a single button press, and that's it.

Audio Balance

Easily control the volume levels between two audio sources with the Audio Balance feature on your PC, Mac, PS5, or PS4!

After a one-time setup, you'll be able to adjust the volume mix on the volume control knob by turning the knob left to right, and vice versa—perfect for use during conference calls while listening to music or podcasts, or while communicating in-game with teammates.

Personalize Everything

Plus, there are loads of customizable settings for the Sound Blaster X4 on the Creative app. The best part? You can choose to tweak each and every element, or switch them off completely.

The Sound Blaster Quality

As it always is with any of our Sound Blaster products, our unwavering Sound Blaster promise—audio quality. The Sound Blaster X4 features 114 dB audio clarity with high-resolution 192 kHz / 24-bit playback for detailed audio that's well balanced and accurate. The extra power from the built-in amplifier also means you'll get a volume boost from the get go.
