These are just impressions of notable IEMs done over a few rock and metal songs which are the staple of my library. Such short auditions over multiple IEMs are bound to be plagued with inaccuracies. In my experience, an audition over the same product within a week (without ear fatigue) may change my mind completely. But hey, Canjam is precisely all about this very experience, noisy show floor included. You won’t find highly descriptive jargony audio terminology here and I’ll just be painting these impressions with broad strokes based on how I
felt. Enjoy!

FIR Audio
I don’t know why I skipped out on Fir Audio last year but I’m so glad I gave the Frontier series a go this year. I’ve seen a few negative impressions from reviewers who I actively follow calling these mediocre or outright bad. I guess we all lookout for different things in our music.
The Frontier series was probably the highlight of my trip this year. Kinetic Bass is no joke, I hesitate to label the massive bass boost we
visually see on graphs “bloat”. The bass contributes more to its impactful and explosive presentation which seriously took me aback on first listen.
Allow me to harken back to a few years ago (2018) when Fir Audio released their M series 3D printed prototypes for auditioning at a Singapore audio store Music Sanctuary (now closed down), I was wholly impressed by its huge open sound from the entry level M2 up to the flagship M5; I’ve never heard anything like it before and I believed that
that was it – e*dg*m*. But alas, when the tunings on the demo units were finalized, the whole series merely sounded unimpressive and mediocre. What had happened to their magic sauce?
Well I’m glad to say that said sauce makes a comeback with their Open Acoustics. It complements Kinetic Bass well, giving all that bass goodness
room to breathe and create this expansive stage.
All members of the Frontier Series have this massive open perceived stage to my ears that none of the other IEMs I’ve listened to this Canjam can even compete with. Of the 3 members, I’d rank the Krypton 5 > Xenon 6 > Neon 4 based on personal taste, here’s why.
Krypton 5: My favorite of the trio; I’ve seen this labelled as the least detailed of the bunch but not to me hahaha. The Krypton 5 and Neon 4 do have similar bass, and somewhat similar treble presentations but the crucial difference lies in their midranges. The Neon 4 has some “honk” in the vocals which may contribute to a sense of richness to some ears. For me, I found myself struggling to “hear through” the honk after a few songs. Enter the Krypton 5: Essentially “fixes” the Neon 4’s mids which made it easier for me to immerse myself in all my favorite tunes.
Xenon 6: Turns that magical boom boom bass up to 11. Too much?
Yes. Enjoyable?
Hell yea. I’d consider this a guilty pleasure. I sense some brain burn-in might be indicated for this level of bass impact. My heart lies with the Krypton 5 likely because the vocals don’t sound as coloured as the Xenon 6 (or Neon 4) for a daily driver IEM.
Neon 4: Covered in the KR5 write-up above, just a snap for your viewing pleasure.
Radon 6: Of course, I tried this fella too. Despite AB-ing with the KR5, I didn’t have enough time to think up of a comprehensive overview of why I’d pick this over the KR5. In essence, it just sounded more “mature” and refined in terms of tonal quality and better-defined separation. It achieves this whilst retaining all the good stuff which made the Frontier Series so attractive to me.
Subtonic
Shoutout to the members of Subtonic! What a friendly bunch. Let’s cut to the chase, the STORM
STORM: Coming from the Fir Audio booth not too long before, SLAM woofers had like… no impact on me. However I stuck with it and it took 1 and a half songs for what the team had been working so hard on to finally sink in. If I could describe the STORM in a single word, it would be “
effortless”.
Simply put, it is probably the pinnacle of raw detail among all IEMs I’ve heard. I suspect the toned-down upper midrange (relative to Harman) contributed to this feeling of immense “
effortless” precision. It didn’t try to blow me away on first listen with forwardness in mids or artificial sharpening with elevated upper mids just south of being strident. I only began to appreciate the STORM for what it was when using my mind’s eye to appreciate that all components of the mix were so damn well separated and well-defined. Just a solid reference grade IEM.
The inaccessibility of the STORM pricewise (for me) makes it just “an experience”.
This or the Radon 6/Krypton 5 you ask? Fir Audio takes a W here. It’s way easier to immerse myself with em furries especially with live performance recordings. The STORM’s massive price tag is almost fivefold more expensive than the amazing Symphonium Helios, only for that last ~15-20% of detail.
On that note, @SymphoniumAudio please give us a more ergonomic Helios & Triton. The STORM is pretty big but it’s way more comfortable. This leads me to believe that the Helios’s size isn’t as much of an issue as shape (for my ears anyway), but I digress.
Nightjar Singularity (prototype): Bassy single DD with fair detail all-around. At this price I think I would top up a little more for an IER Z1R
Nightjar Project Bass (prototype): AKA “Duality” as coined by the community. Chang let me use it with an impedence adaptor which increased the bass and wowza, that was a lot of bass. Not something I would ever purchase for myself but this and the Singularity does the whole basshead signature heaps better than the Maestro/Scarlet Mini. As compared to Fir’s Kinetic Bass, the lack of that open staging Fir Audio achieves makes the overwhelming bass feel a little suffocating; I literally found myself holding my breath at times
64 Audio
64 Audio U4s: I couldn’t pass up the chance to give this
spanking fresh new release a go. Bass only had a modest amount of impact and sounded fairly dry. Quite an inoffensive sound with a relatively reserved upper midrange. The M20 module sounded a little muddy while the M12 cleaned up the signature yet managed to sound balanced. Bass texture also improved with the M12 due to increased control reducing bloat. It goes without saying that I largely preferred the M12 over the M20.
The U4s is not a bad choice with the added benefit of their pressure-relieving technology which I’m quite into. I foresee this growing on me with future listening; this calls for another audition when I’m fresh in a quiet environment.
Fatfreq
Fatfreq Scarlet Mini (and Maestro Mini): Just “okay” sounding. Mids and highs sounded two-dimensional and compressed while its purported big bass merely clouded over the mix. I’d easily choose the Symphonium Meteor over this.
Elysian
Elysian Diva (middle setting): The infamously elusive Diva which made its debut in Canjam SG 2022 makes a return in a new UIEM form factor with a metal spout. Still sounds pretty good with decent technical chops but I think I now prefer the Gaea.
Elysian X Effect Audio Gaea: Next to the Gaea, the Diva sounds a little limp in the bass. The Gaea wholly embraces Elysian’s “exciting V-shape” house sound in a much smaller form factor. I think it’s a tough fight between the Gaea and Helios but previous auditions tell me that the Gaea may get fatiguing for my ears after a few songs despite the initial thrill. Quite the matter of taste here.
Elysian prototype: This pic is just an Annihilator dressed in silver, the actual prototype was dressed in iconic Annihilator gold. Through the clear acrylic body, a custom DD with a matching gold casing was visible among the array of various drivers used. The result? A pleasant warm sound somewhat reminiscent of the Oriolus Szalayi… didn’t make any notable impression for an Elysian IEM (take with several grains of salt, I only listened to 2 songs). Lee tells me that it is meant to be aggressive but perhaps my ears were just too tired in addition to the conducive show floor environment - it just didn’t impress at all. I preferred the Diva and Gaea over this prototype.
Softears
Softears Studio4: Decent 4BA setup with a relaxed yet balanced presentation. It didn’t strike me as particularly impressive though, imaging and separation could be more well-defined even for this pricing. I’d rather top up a little more for something more exciting and “ear-catching” like the Moondrop Variations.
Symphonium Audio
You might have noticed that I have mentioned Symphonium Audio a few times over the course of this writeup. No pictures but they deserve a special mention for their class-leading performance and build quality topped off with
reasonable pricing in today’s market. Their lineup has easily attained a benchmark status whenever I test something new.
I was disappointed to see that neither of the two new IEMs teased on their Instagram made an appearance. I’ll be keeping a close lookout this 2023!
