Design and features

The SXFI TRIO is a really handsome set of earphones. I appreciate that they’re not very large, despite the 10mm drivers in them, and the mini-amp embedded in the control stick keeps things compact.

They’re all black, except for the magnetic drivers on the outside of the earpieces. The cable is double wrapped in copper and kevlar and feels extremely durable. They have a premium look and feel.

The rubber earbud tips are firmly rooted in place, it takes some doing to get them off and attache replacement tips.

There is a mic located on the right wire, and the control “stick”, I’d call it, is located just below where the left and right wires join. On this stick is the SXFI on/off button, volume controls, and a play/answer button. There is also a tiny LED light that glows green and orange if the SXFI effect is turned on or off, respectively.


Normally, the only setup you’d have to do with the pair of earbuds is taking them out of the package, maybe swapping earbud tips, and plugging them in. Boom, all set.

The SXFI TRIO comes with 6 earbud tip sizes to ensure a secure fit. A good seal is imperative with earbuds to make the best use of the natural acoustics of your ears. I really appreciate the TRIOs come with twice as many earbud tips as a normal pair would… instead of small, medium and large, you get a full array of sizes from 10mm to 16mm diameters. I ended up being good with 13mm.

Wouldn’t you know it that despite the granularity in tip sizes, my ears are a size in between 13mm and 14mm, but the smaller size still provided a good seal and didn’t hurt after an hour.

The TRIO has a USB-C connector, which limits the number of devices it can connect to. I could use them with my MacBook Pro, iPad Pro and Nintendo Switch, but not my iPhone.

It’s worth mentioning that the number of non-iPhone smartphones these headphones work with seems small. Maybe the Google Pixel series. It doesn’t seem compatible with micro USB phones, anyway, according to the site.

As mentioned directly on Creative’s website:

  • The SXFI TRIO has been designed to work with fully compliant USB-C Android phones, for example, the Google Pixel series. Some phones display partial compatibility with the SXFI TRIO, and may have limited mic functionality.
  • Most Samsung phones implemented their USB-C differently from the Android standard, and thus exhibits mic compatibility issues. The music playback function is not affected.
  • The SXFI TRIO is not compatible with iPhones and older USB Micro-B phones.

Provided you have something you can actually use with the headphones, great! We can get to the last step in the process.

Creative makes a smartphone app that scans your ears that head to calibrate the audio, customized to your face and ear shape. I haven’t the slightest clue how this works, or if it does anything at all. According to Creative’s site:

… complex algorithms and computationally intensive techniques to custom fit audio, for every individual, through a sophisticated Head and Ear-Mapping process.

I have to assume it does something, but it sounds so farfetched, and there was nothing on the site that says how or why it works, so I’m a little skeptical.

Not sure about all that.

Pro tip: you might want to get someone else to help you with this process, as you have to take a picture of the sides of your head, lining up an overlay of an ear with your own.

I managed to do it, and running the iPhone app on an iPad Pro, no less, because I didn’t have a phone with a USB-C connection. I’m a little confused why there even was an iPhone app, unless you can get some sort of USB-C to Lightning adapter. I don’t see how you’d connect the TRIO.

After the photos were snapped and the analysis was complete, the TRIO updated itself through the app, installed the latest firmware, and saved the settings in the earphones themselves. That’s awesome. Because I don’t want to have to do that setup ever again.


Finally, we get to what really matters in any set of earphones. How do they sound? And what’s up with this Super X-Fi technology, anyway?

Creative SXFI Trio USB C Earbuds 005

First off, these TRIO headphones really trick your brain into hearing an expanse of sound. Typically, earbuds sound a little bassy, and have what almost feels like a claustrophobic sound. They’re close and personal and sort of feel like listening to a radio in a closet.

The TRIOs sound like listening in a concert hall.

I imagine that’s why they put that button on the control stick that switches the X-Fi on and off. It’s a pure gimmick to flip back and forth between “normal” and X-Fi modes, just to hear how much more open and airy it feels. I imagine it has something to do with how the earphones mix and balance the channels and frequencies, but honestly, it’s really something to hear, the difference between these and, say, my AirPods Pro.

And if you’re listening to media that utilizes 7.1 surround sound, that’s exactly what these little TRIOs were made for. Throw on an action scene from a recent Star Wars or Marvel movie, and the TRIOs do a great job of throwing the sound all around you, not just left and right channels, but front, back and center as well.

If you have access to an equalizer in the app you’re using, it’s worth messing with the settings a bit to find that sweet spot for the type of music you’re listening to. Boosting the bass a bit would be my suggestion, as X-Fi mode seems to lean away from the low end sounds to ensure the spatial effect isn’t weakened.

Bass is usually a bit weak on earbuds, anyway, to keep the drivers down to a manageable size and weight.

One thing that I wish I could have changed was the wire. Let’s face it, with the explosion of Bluetooth 5 earphones and the ubiquitous AirPods, having to deal with a wire again felt just plain awful. I get that they’re necessary to drive that much power to the amplifier and all… but it actually made me glad that I couldn’t use the TRIOs with my iPhone, and instead had to be fitted to a more permanent device like a laptop or my Switch.

Speaking of which, I played through several games, and they all sounded great. I decided to plow through a couple levels of violent rhythm game, Thumper, which relies heavily on sound, and the driving, pounding soundtrack engulfed my mind.

Every test I threw at it … video streaming, music apps, gaming … everything felt wide and atmospheric. It’s a wonderful little engineering trick, but it really does present layers of depth, and amazingly well for such a tiny package.

What I like

  • Full-surround sound in a tiny package
  • Very clear, sharp spacial sound
  • Settings saved to the headphone memory after initial setup

What needs to be improved

  • Not compatible with many phones
  • The “ear mapping” seems pretty bogus

Final thoughts

The Creative SXFI TRIO presents a pleasing pastiche of expansive audio space. It’s an interesting illusion, an impressionist painting version of surround sound, that comes close enough to a full 7.1 audio system in a tiny, portable package. If you’re looking for some fantastic-sounding earbuds and have the devices to handle it, these TRIOs come highly recommended.

    1. I used the headphones on some Zoom and Microsoft Teams video calls and the party on the other end had no issues hearing me. The sound on my end was good. It was pretty quiet around me during the call.

      I didn’t get a chance to see how they worked on the go, however, because my iPhone doesn’t support USB-C connection… so I can’t speak to whether or not the mic picks up a lot of ambient noise.

  2. I know this is an old article, but i wanted to jump in just to assure you that the head/ear mapping does indeed do something. I’ll try to keep this as short as I can. Even though we have only two ears, we can still determine if a sound is coming from in front of is or behind, as well as above and from various angles in between. This is possible because of the shape of our ears and the path sound takes before it reaches our actual ear-holes. Our brain detects the subtle differences in timing and frequency response in order for us to perceive sound in three dimensions. This effect can be reproduced for headphones or earphones via a process called Head Response Transfer Function, or HRTF. This has been implemented before by various manufacturers, usually in stand-alone or inline amps/processors, based on a generic “typical ear” model. Of course, the quality of the effect varied, depending on how closely your ears matched the model, and how well your headphones or earbuds frequency response curve matched the model.
    What Creative has done is to attempt to improve on generic HRTF profiling by personalizing it to the exact shape, size, and structure of the actual listeners ear, as well as the distance between them. In this particular product, additional accuracy is achieved my “marrying the processor to s specific earbud’s characteristics. They actually make a standalone inline version that can be used with any headphones, along with profiles that can be loaded to match quite a long list of popular models.
    No whether or not you find the effect realistic nor enjoyable is a matter of opinion, but rest assured the ear mapping really is doing something, and the results really are improved after mapping (which you might have noticed if you skipped mapping and tried them as-is before completing the mapping step.

    1. That’s really interesting, thanks for the comprehensive explanation! I figured in-ear headphones would sound the same to everyone, that the inner ear would be shaped more or less the same for everyone as opposed to the outer ear, which is extremely unique for everyone. There must be some correlation between the inner and outer ear shape.

      I haven’t checked to see if there was a difference in pre and post ear scan settings. I’m going to guess I wouldn’t be able to tell the difference, anyway, I don’t have audiophile level hearing.
