In addition, it also comes with greater connectivity options compared to its predecessor (it is compatible with PC, Mac, PS4 / PS5, Switch and even with iOS and Android smartphones) and with very easy-to-use physical controls to control everything.

Of course, Creative has integrated its proprietary technology Super X-Fi, capable of recreating a soundstage of a high-quality surround sound system on headphones, customizing the audio experience to the shape and size of the user’s ears. This technology creates a more natural audio experience, according to Creative, allowing them to enjoy better immersive audio, greater depth of sound, and ultimately greater immersion. According to the manufacturer, it is as if the user were in the cinema, in the middle of the battlefield of the games, or in a concert.

This USB DAC also incorporates the renowned technology Surround Virtualization, developed for more than 30 years by the audio experts of the brand, one of the star characteristics of this new model. This technology significantly improves the spatial information of the audio and optimizes it to offer the user a much more immersive experience that offers up to 7.1 independent or virtual audio channels depending on the user makes the relevant connections.

Users using this external sound card on a Windows PC can enjoy the Dolby Digital Live audio codec, which transforms audio content to this multi-channel surround audio standard in real time. It also comes equipped with the ability to support studio-quality headphones with up to 600 ohms and 114 dB for crystal-clear reproduction with up to 24-bit 192 KHz frequency response.

Communications, its strong point

With the new SmartComms Kit, the Sound Blaster X4 doubles as a versatile sound card that can offer users a simple and smart way to communicate over the Internet. For example, with your function Voice Detect The microphone will automatically mute when it detects that the user is quiet to completely eliminate background noise and will re-activate when it detects that they are speaking, all with near-zero latency. There is no need to press buttons to mute the microphone since the device does it automatically, but it still incorporates a physical button for it.

As if this were not enough, it also incorporates a bi-directional noise cancellation function, which eliminates unwanted background noise to avoid annoyance in online communications. It works on both ends: NoiseCliean-in for incoming audio and NoiseClean-out for outgoing audio, offering the clearest possible communication in the industry.


On the other hand, it also has the technology CrystalVoice which enhances the voice for recordings and conversations so that the human voice will be much clearer and, true to its name, crystal clear. For users looking to explore additional and curious options, it also has the technology Voice Morph which is nothing more than a modulator that allows changing the user’s voice with a list of predefined profiles (for example, to have the voice of a squirrel, of a woman when you are a man or a man when you are a woman).

All these features are accessible through Creative’s complete control software, available for both PC and Mac as well as mobile devices and that you can download for free from its website.
