Your phone, computer, or game console already has both of those, so why opt for an <a href=\"https:\/\/www.howtogeek.com\/710420\/what-is-an-external-dac-and-do-you-need-one-for-a-pc\/\">external DAC<\/a> and amplifier?<\/p>\n<p>Sound quality is the first answer. While any digital device with a headphone jack has a built-in DAC and headphone amp, they\u2019re not a high priority on many devices. The second is that Creative has added quite a few features here. But first, let\u2019s look at the device itself.<\/p>\n<p>The Sound Blaster X1 is small, using a similar finger-sized form factor to other portable DACs \/ <a href=\"https:\/\/www.howtogeek.com\/746779\/what-is-a-headphone-amplifier-and-do-you-need-one\/\">headphone amps<\/a>. It\u2019s a simple design with a USB-C port on one end, a 3.5mm headphone jack on the other, and the controls on the face of the unit.<\/p>\n<p>Before you plug in the included USB-C cable, the Sound Blaster X1 measure just over 2.5 inches long. Once you add the USB cable and plug in your favorite headphones, the footprint gets somewhat larger, but the size and weight of the X1 alone likely won\u2019t ever be worth thinking about.<\/p>\n<p>The onboard controls are simple. You have volume controls\u2014very handy for adjusting playback without reaching for your phone\u2014with a multifunction button in the middle. Then there\u2019s one more conspicuous button. This is the Super X-Fi button, which switches that feature on and off.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><a name=\"autotoc_anchor_1\"\/>Getting Started With the SXFI App<\/h2>\n<figure style=\"width: 1200px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-828898\" data-pagespeed-lazy-src=\"https:\/\/mailinvest.blog\/wp-content\/themes\/breek\/assets\/images\/transparent.gif\" data-lazy=\"true\" data-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2022\/08\/creative-sound-blaster-x1-app.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"Creative's SXFI app\" width=\"1200\" height=\"675\" src=\"https:\/\/mailinvest.blog\/wp-content\/themes\/breek\/assets\/images\/transparent.gif\" data-lazy=\"true\" data-src=\"\/pagespeed_static\/1.JiBnMqyl6S.gif\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\">Kris Wouk \/ How-To Geek<\/span><\/figcaption><\/figure>\n<p>You can use the Sound Blaster X1 without setting it up, but to make the most of the device, you\u2019ll want to use Creative\u2019s SXFI app (available for <a href=\"https:\/\/apps.apple.com\/us\/app\/sxfi-app\/id1323992913?at=1010l392g&amp;ct=htg828885\">iPhone<\/a>, <a href=\"https:\/\/apps.apple.com\/us\/app\/sxfi-app\/id1323992913?at=1010l392g&amp;ct=htg828885\">iPad<\/a>, and <a href=\"https:\/\/play.google.com\/store\/apps\/details?id=com.creative.apps.superxfiplayer&amp;hl=en_US&amp;gl=US\">Android<\/a>) to set it up. If you have an Android device or iPad with a USB-C port, it\u2019s best to run the software there, as you\u2019ll see shortly.<\/p>\n<p>Once you install and register with the app, it\u2019s time to take some pictures of your ears. Yes, Creative\u2019s Super X-Fi adjusts its sound based on mapping your ears and the shape of your face. It\u2019s handy if you have someone to take photos for you here, but I imagine with some time and a mirror or two, you can get through this process on your own.<\/p>\n<p>After you\u2019ve completed the ear and head mapping portion, the app asks you to select the headphones you have. Not every model of headphone is listed, and there is an emphasis on Creative\u2019s own headphones, but my <a href=\"https:\/\/www.amazon.com\/dp\/B00018MSNI\/?tag=lsmedia-11001-20\">Sennheiser HD650s<\/a> were on the list.<\/p>\n<p>At this point, assuming your device has a USB-C port, you can plug the Sound Blaster X-Fi in, and your settings will transfer onboard.

This chip is used fairly often in more budget-oriented MP3 players and digital audio players, and is fairly well regarded. To drive your headphones, the X1 uses a Ti\/Burr-Brown INA1620 dual audio operational amplifier.<\/p>\n<p>One thing that\u2019s interesting about the Sound Blaster X1, and something you won\u2019t necessarily see even in higher-priced competitors, is the headphone support. The X1 supports headphones up to 600 <a href=\"https:\/\/www.howtogeek.com\/821496\/what-is-impedance-and-sensitivity-in-headphones\/\">ohms<\/a>, meaning it can theoretically drive some headphones that are notoriously hard to power with a portable amp.<\/p>\n<p>To test this out, I chose my Sennheiser HD650s to listen first. For this portion, I listened with Super X-Fi turned off. For more about that, <a href=\"#moka_anchor_SuperXFi\">see the next section of this article<\/a>.<\/p>\n<p>It\u2019s not like if you plug the HD650s into your phone\u2019s headphone jack (assuming it has one), they won\u2019t work. They still make sound, but the maximum volume is limited, and the audio doesn\u2019t shine the way it does when the headphones are paired with a good amp.<\/p>\n<p>When I plugged in the HD650s with the Sound Blaster X1, I was surprised by the volume first. Then I noticed that the undefined low-end and muffled highs I associate with an amp struggling to drive the HD650s weren\u2019t anywhere to be found.<\/p>\n<p>Now, compared to my usual setup\u2014a <a href=\"https:\/\/www.amazon.com\/dp\/B09RCZW5WY\/?tag=lsmedia-11001-20\">Schiit Audio Modi DAC<\/a> and <a href=\"https:\/\/www.schiit.com\/products\/asgard\">Asgard headphone amp<\/a>\u2014there were differences. I noticed some more sparkle in the high end on the more expensive setup, whereas the Sound Blaster X1 still had a very slight veil over the treble.<\/p>\n<p>That said, this wasn\u2019t exactly a fair test, since I was testing the X1 against a setup around five times its price. Considering the stacked odds, the X1 held up fairly well.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><a name=\"autotoc_anchor_3\"\/><a name=\"moka_anchor_SuperXFi\"\/>Super X-Fi and the Creative App<\/h2>\n<figure style=\"width: 1200px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-828900\" data-pagespeed-lazy-src=\"https:\/\/mailinvest.blog\/wp-content\/themes\/breek\/assets\/images\/transparent.gif\" data-lazy=\"true\" data-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2022\/08\/creative-sound-blaster-x1-super-x-fi.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"Super X-Fi button on the Sound Blaster X1\" width=\"1200\" height=\"675\" src=\"https:\/\/mailinvest.blog\/wp-content\/themes\/breek\/assets\/images\/transparent.gif\" data-lazy=\"true\" data-src=\"\/pagespeed_static\/1.JiBnMqyl6S.gif\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\">Kris Wouk \/ How-To Geek<\/span><\/figcaption><\/figure>\n<p>As mentioned earlier in the article, Creative\u2019s <a href=\"https:\/\/us.creative.com\/sxfi\/\">Super X-Fi<\/a> aims to make your headphones sound less like headphones and more like speakers. Basically, using some <a href=\"https:\/\/www.howtogeek.com\/788867\/what-is-digital-signal-processing-dsp\/\">DSP<\/a> trickery to trick you into hearing more space around you. When it works, it works quite well.<\/p>\n<p>I say when it works because the first time I hit the Super X-Fi button on the X1, I thought I\u2019d hit the \u201cmake everything sound bad\u201d button. Everything was suddenly tinny and harsh, and I quickly turned the feature off. Of course, this was before I\u2019d used the SXFI app to set up the X1.<\/p>\n<p>Afterward, I still didn\u2019t like the sound of Super X-Fi for music. To me, it sounded too much like listening to music on a <a href=\"https:\/\/www.howtogeek.com\/775329\/audio-channels-how-many-do-you-need-for-a-home-theater\/\">5.1-channel home theater system<\/a>, which I\u2019m not a fan of, real speakers or fake.<\/p>\n<p>On the other hand, Super X-Fi worked great for movies and TV. I\u2019d hit the button while watching a movie on my laptop, and suddenly, it sounded like I was in a room with speakers everywhere, rather than just wearing headphones. This added dimension was especially noticeable with movies.<\/p>\n<p>If you\u2019re using the Sound Blaster X1 on Windows or macOS, make sure to download the <a href=\"https:\/\/support.creative.com\/Products\/ProductDetails.aspx?catID=1&amp;catName=Sound%20Blaster&amp;subCatID=1090&amp;prodID=23908&amp;prodName=Sound%20Blaster%20X1&amp;_ga=2.190315947.1836923717.1661463064-1780139239.1661463064\">Creative App<\/a>. This adds more features to the X1, like adjustable EQ and CrystalVoice, which can make the mic on your headphones or gaming headset sound clearer.<\/p>\n<p>Speaking of gaming, the Creative App also has numerous sound modes for gaming. This ranges from a standard \u201cGaming\u201d preset to presets for different genres and even specific games.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><a name=\"autotoc_anchor_4\"\/>Should You Buy the Creative Sound Blaster X1?<\/h2>\n<p>I honestly wasn\u2019t expecting to be as impressed with the sound of the <a href=\"https:\/\/us.creative.com\/p\/sound-blaster\/sound-blaster-x1#buy-menu\">Creative Sound Blaster X1<\/a> as I was. While it isn\u2019t necessarily meant as one, this could be a great budget pick for your first <a href=\"https:\/\/www.reviewgeek.com\/8350\/everything-you-need-for-a-mobile-audiophile-setup\/\">mobile audiophile setup<\/a>, assuming your phone or player has a USB-C port.<\/p>\n<p>The only slight issue with that is the lack of support for native 192 kHz. With more digital music stores and services offering 192 kHz files and streams, it would have been nice to see this here. That said, considering the price, some compromises are understandable, and you can still listen to higher resolution files, they\u2019re just downsampled to 96 kHz.<\/p>\n<p>The Sound Blaster X1 is the DAC \/ headphone amp equivalent of a Swiss Army knife, with features for music fans, film buffs, and gamers alike.
