Effect Audio - CODE Series - CODE 24
I’m not here to persuade the unpersuadable. Cables have been one of my more recent obsessions within the audio hobby. For me, cables are a fine tuning tool. A link in a chain that can ultimately enhance or impair a particular set up. So with that out of the way, let’s get it.
Nothing Is What it Seems
Say what you want about the CODE series, because I’ve likely said the same thing. I was first introduced to this cable through a Head-Fi prototype tour sponsored by Effect Audio. The prototype cables were bare-bones. No termination hardware, no y-splitter, and no ear hooks. To be completely honest, I wrangled with these puppies for about an hour and shipped them off the follow day. No ear hooks on a CODE series cable should be a crime. Following this initial impression, I had no interest in further testing the CODE 24 or 24C.
Fast forward to CanJam NY. Day 2, I was committed to sampling some new cables and what better way to start the day than by visiting a fellow head-fier and friend
@Sebastien Chiu. Instead of starting from the bottom-tier products and working up, I prefer to do the opposite. Set expectations high and work down. This strategy typically allows me to save a few precious minutes at each booth since cable performance typically degrades pretty quickly with price. Since I already own, or have owned, quite a few EA cables, there were only a handful on my list to try. Centurion I Chiron I Cleo II Octa. While all 3 did impress me, I would need a lengthier, more controlled atmosphere to truly evaluate. They just weren’t what I was looking for based on first impressions. Starting to lose faith, I thought why not and went in for the CODE 24.
Instantly, this was something I really jived with. A significant sub-bass boost that was well controlled, impactful, and didn’t bleed into the lower mid’s. The Mid-range remained neutral, maintaining the exceptionally natural timbre of my beloved NGaudio Khaos. A healthy boost of air, stage and imaging. Was this the same cable I previously heard? Did I make a mistake writing this cable off? After a couple tracks, I was sold and immediately emailed Andrew over at MusicTeck to put in my order.
If I’ve learned anything over the last two years when it comes to cables, my sonic preference almost always leans to a solid core structure. Why? Great question because I absolutely despise the ergonomics of them BUT sonically, they just really do something for me.

Physical Analysis
Cable Aesthetics and Functionality
So let’s talk about the cable itself. Like all recent CODE series releases, ergonomics remain sub-par. But I can confidently say the CODE 24 is much improved over the CODE 23. I do the majority of my listening at a table or stationary position so this is less of an issue for me. For testing purposes, I did sport the CODE 24 out on a few walks with the pups and with the assistance of the stock Y-split slider, or what EA refers to as the ‘gem’, I had no issues of dislodged IEM’s or moments of despair. Is it perfect? Far from it, but it’s manageable. I also want to point out the improved Y-splitter design over the CODE 23. The slider is almost fully concealed within the outer chassis when not in use and is much more satisfying to adjust.
The cable and hardware is finished in a deep ‘cosmic’ blue, complimented by a tasteful dose of golden accents. Though I typically prefer a more neutral look, this cable is absolutely stunning with the right IEM pairing. If you’re like me, aesthetics play a significant role when selecting a permanent pair up with a set of my IEM’s in my collection.
I purchased my CODE 24 with a permanent Pentaconn 4.4mm termination based on preference but it should be noted that the default cable is equipped with TermX. Like all other current EA offerings, this cable has ConX for adaptability. You will receive a basic set by default, but are able to add additional connectors if needed. I personally hesitate purchasing any cable without swappable IEM connectors anymore. Mainly due to a revolving door of new IEM’s showing up on my doorstep.
There is No Sound in Space
Impressions from Earth
This cable has been ‘burned in’ for roughly 100 hours. Sources include the Sony WM1ZM2 and Shanling M9+. IEM’s used include Oriolus Monachaa/ Elysian Annihilator/ AME Raven. My music selection for this review varies widely, including but not limited too Daft Punk, 3LAU, GoGo Penguin, Glass Beams, Hans Zimmer, The Black Keys, Glass Animals, Microwave, Northlane, Erra, Ingested, Knocked Loose, Hollow Front,
Bass - Immediately, I notice a significant boost in quality, quantity and impact. Not quite to CODE 23 levels, but there is an unquestionable improvement to the low end with the CODE 24. The low boost manages to fall off just shy of the mid-bass region maintaining a notable delineation. The biggest problem I’ve had in the past with pure silver cables is the mid-bass boost muddying the mix. Not here. Granted this is a hybrid, but I felt it should be noted to alleviate any potential concerns.
Mids - Lower mid’s remained exceptionally neutral, maintaining the natural timbre of all IEM’s tested. The upper mid’s however do get a little treatment here, specifically in clarity and overall spaciousness. Vocals come through with more authority and weight without being pushed forward in the mix. This is a massive plus in my book, as I typically prefer vocals to remain slightly recessed in the overall mix. Lastly, I’d like to highlight the overall smoothness in the upper-mid range presentation. The CODE 24 allows for a highly musical experience without sacrificing resolution.
Treble - There are some audible enhancements to the treble region as well, though nothing transformative. What I found to be most impressive was the overall improvement in imaging and instrumental separation. In addition, the high end of the spectrum receives a tasteful injection of sparkle without introducing any sibilance or unnatural peaks.
Techs - The most consistent improvement I noticed throughout my testing was a natural growth in stage width. This boost allowed for a greater sense of space between tracks and an overall improvement in resolution and detail retrieval. I wouldn’t say the CODE 24 increases or emphasizes micro/ macro details, but rather allows for more information to come through with the growth in stage.
Comparisons
Effect Audio CODE 23 - For those unfamiliar, the CODE 23 is the pure copper variant in the CODE series sporting a $599 price tag. First and foremost, ergonomics are greatly improved over the 23. I also prefer the 24’s new slider and hardware design. I do find the CODE 24 a bit more picky in pairing. Sonically, the CODE 23’s sub bass presentation and dynamic performance takes the cake. While the CODE 24 is no slouch in either department, it provides an overall smoother, more relaxed presentation. I do prefer the CODE 24’s influence over the treble region, adding that extra sparkle and air within the mix. From a strictly sonic perspective, both are fantastic choices for the price.
Effect Audio Fusion 1 - While the Fusion 1 may not live under the CODE series umbrella, it does have an undeniable resemblance in cable geometry. Instead of pure copper or silver-plated copper, the Fusion 1 is constructed of gold plated silver litz, pure silver litz and pure copper litz. The Fusion 1 is also the most expensive of the bunch, carrying a $999 price tag. Ergonomics between these two cables are pretty darn comparable. Aesthetically, I think the Fusion sports a more sophisticated look that’s easier to match with IEM’s if that’s important to you. Starting with the low end, the Fusion 1 tends to tighten up the low end resulting in a more controlled, punchy presentation compared to the CODE 24’s overall boombastic boost to this region. I also sense a richer, ever so slightly forward presentation to the mid-range with the Fusion. Both cables display exceptional clarity and air. Technicality improvements are pretty consistent between the two.
Eletech Perseus - I think these cables display a lot of the same enhancements, but the Perseus’s improvements are just a bit more subtle. The Perseus has great sub bass depth and texture, just with less quantity. Mids seem slightly recessed on the CODE 24, but I attribute this to its explosive sub-bass and modest treble ‘coloration’. Both cables provide a substantial boost to overall staging. Again, I wouldn’t call one better than the other. My choice between the two would strictly come down to the IEM I was pairing it with.
Verdict (With a Grain of Cosmic Dust)
Conclusion
If there’s anything I’ve learned in this hobby, it’s not to buy a product solely based off hype. Too many times have I been disappointed with a product praised by the community. Do your research! I also recognize that demoing products is not always an option so there is that. Bottom line, take my impressions with a grain of salt. The music I listen too, or what a demand from my gear may significantly differ from you. Theres plenty of people that will claim this cable is trash and that’s OK. I don’t require public validation and neither should you. Enjoy what you enjoy! For me, I love having this cable in my arsenal. It’s aesthetically unique, versatile, well constructed and provides a specific set of tricks I can use to fine tune sets in my collection to my preference.
