Rich bass with great overall tuning. Pleasant timbre. Resolution could be better. Treble could use more liveliness.

Youtube Video Summary

Single 10 mm dynamic done right. Singularity hits with that coveted one-driver cohesion: a bright, energetic top end riding on subway-tunnel bass swell that feels physical without drowning the mix. Layers stack cleanly, imaging projects like a stereo in front while ambience wraps overhead, and even on modest amps the presentation stays delicate yet weighty. On better chains (think tube or high-end portables), the staging and microtexture climb further, pointing to a legitimately kilobuck-worthy tuning and execution.

Everything around the sound? Mixed. The shell is compact but a bit boxy, fit can be finicky until the right tips are found (Dunu S&S or foam-stuffed silicones help), and the accessory spread—big case, stickers, adapters to 4.4/3.5—is fine but unexciting. The stock cable is soft yet feels mismatched: hardware sized like it’s for an 8-wire, odd strain bits, and overall not $1.3k-luxury. With the IEM sitting at roughly $1,300 bundled to a $500+ “Vanguard 2-wire,” upsell options rocket pricing to absurd heights; there’s no “no-cable” variant, which is the real gripe.

Verdict: as an IEM, it’s a knockout—cohesive, exciting, and vividly dynamic to the point of becoming a daily carry. As a total package, it’s weighed down by cable bundling shenanigans and a so-so fit. With a 43 Ω load, cable influence should be minimal anyway, so the savvy move is to buy the cheapest cable option, swap in a comfortable $50 aftermarket, and enjoy one of the better-sounding single-DDs out there.

Nightjar Singularity reviewed by Audionotions

Audionotions 7.5 Reviewer Score
I fully expected these to be an overwhelmingly bass heavy set but instead got something quite different. Singularity bass is boomy and somewhat pillowy, extending deep and with almost atmospheric levels of elevation - seriously, just look at that frequency response... Now, pillowy is something that I don't normally associate with quality bass and it goes without saying that this adjective used to describe bass also suggests a lack of impact but it does rumble and there is meat to the bass, just lacking that harder, crisper, leading edge to the attack. And this is bad right? Well, as I am finding out, not exactly. Rather than having bass be the star of the show, instead, the bass serves as a backdrop to mids and treble which take center stage. This quite possibly the most technically proficient single DD set I've heard and trades blows with the IE900, perhaps having an edge in attack and dynamics. Transients are razor sharp and notes are very well defined. Vocals and instruments stand out and apart in the mix in a way that you usually would expect only from sets with multiple BA drivers, let alone one single DD. Timbre is pretty good as well - there is a bit of brightness here but it never is sharp or jarring - it's not the most timbrally accurate I've heard but it also doesn't have anything that sticks out to me as offensive or off putting. Instead, it seems that brightness adds to the sense of technicalities. And this is all with a very significant bass backdrop that surprisingly doesn't bleed or introduce mud into the mix. My theory (and I'm definitely not an expert here) is that if the bass were to be too punchy or impactful here, it would overwhelm the entire sound signature. But that's just my theory. This is a basshead IEM for mids and treble lovers. That said, as great as this set is, I think IE900 still holds the crown of best single DD set because I'm just a sucker for tactile bass and nothing quite matches the physicality to be found on that Senny.

One of the best basses ever inside a very small and comfortable shell. The rest of the tuning is still pristine but the technicalities are bottlenecked by the single DD.

So simple and nice it's hard to not love.
Youtube Video Summary

Alien Brain arrives as a single-DD + 4BA hybrid around $1,000 with a truly peculiar shell: the rounded, “alien cortex” faceplate is magnetic, uses MMCX, and can be tricky to seat. The unboxing is lavish—two cables (including 4.4 mm), a compact magnetic leather case, a USB-C DAC/amp, foams plus “sticky” tips, cleaning tools, and extras. Fit is the hurdle; tip-rolling is essential, but once positioned correctly, comfort and seal fall into place.

Tonally, this set pursues a balanced, all-rounder tuning with a near-ideal bass shelf, lively but controlled upper mids, and sparkly yet composed treble. There’s punch and detail without drifting into fatigue; extension is strong, but staging isn’t the most expansive and note weight isn’t “thumpy”—this isn’t a bass-head cannon, more a clean, grounded presentation. The FR shows a touch of 1 kHz energy and smooth ripples through presence/air that favor natural timbre over hyper-etched brilliance, making it a long-session, non-fatiguing listen.

Versus Campfire’s own lineup, it’s far more normalized than the colorful Trifecta, better extended than the warm Axion, and closer in poise to Moon Rover but with a bit more bass and refinement. Compared to peers like Dunu Glacier or DA Mecca, Alien Brain trades V-shaped excitement for cohesive neutrality, and avoids the upper-mid glare that can scare off listeners. Net result: a strong recommendation for those who can manage the fit and want a high-end Campfire that does something new—not the classic house warmth, not sterile flatness, but a realistic, well-rounded signature with broad appeal.
