The short version

What to know.

A ~$380–400 hybrid IEM (one 9.2 mm LSR dynamic driver plus three Sonion balanced armatures) that is Elysian's first affordable set, tuned safer and more neutral than the brand's flagship house sound. Thirty-seven measurement rigs agree on its shape: a deep sub-bass shelf with a comparatively lean mid-bass, an early, modest ear-gain peak, a presence peak near 4.7 kHz and a relaxed 5.5–7 kHz band. Sources broadly agree on its strengths — class-leading sub-bass extension, high resolution and precise imaging, a clean midrange with vocals (especially female) as a highlight, a wide if shallow stage, a premium shell and an excellent stock cable. They split on five axes: bass (lean mid-bass vs big, punchy low end), treble (smooth and safe vs bright and energetic, occasionally hot), dynamics (blunted and 'too safe' vs lively and hard-hitting), fit (comfortable vs a short, wide nozzle that won't hold a seal) and value (a lot of Elysian for the money vs a brand premium in a crowded bracket). Seal and fit sit under most of it: a shallow or broken seal is exactly what 'lean and dry' sounds like, and a higher-impedance source adds bass. Critics also note the retail tuning is tamer than the brighter pre-production unit shown at CanJam. Head-Fi's 42 member reviews average 4.3 of 5; Amazon's small owner set averages 3.8.

About this product

The base Elysian Acoustic Labs Pilgrim (often written simply 'Elysian Pilgrim', sometimes 'Pilgrim OG'): a hybrid with one 9.2 mm LSR dynamic driver, one Sonion 2300 balanced armature for the mids and two Sonion E50s for the highs via a 3-way crossover, on Pentaconn Ear connectors. Not the $799 Effect Audio x Elysian 'Pilgrim: Noir' — a darker, warmer tune with a different driver split (two BAs for the mids, a Knowles tweeter), a 4-way crossover and an Eros S cable. The base Pilgrim is itself manufactured by Effect Audio.

The Elysian Acoustic Labs Pilgrim is the Malaysian boutique's first genuinely affordable in-ear monitor. Elysian built its name on pricey, lavishly-tuned flagships like the Annihilator and DIVA; the Pilgrim, launched in spring 2024 at $399, brings the house name down-market, still tuned by founder Lee Quan Min and built around a single 9.2 mm LSR dynamic driver for the lows and three Sonion balanced armatures for the mids and highs. It ships on Pentaconn Ear connectors and is manufactured by Effect Audio, which also co-makes the pricier, darker Pilgrim: Noir.

It arrived heavily hyped as 'Elysian for the masses', and two years on it has one of the most thoroughly measured and argued-over records in its class — nearly forty measurement rigs, dozens of Head-Fi reviews, a long owners' thread. The measurements agree closely; the listeners do not. They split over whether the low end is lean or plentiful, whether the treble is smooth and safe or bright and energetic, whether the fit is comfortable or maddening, and whether $400 buys a bargain or the Elysian name. Much of that, it turns out, traces to one thing: the seal.

A good fit for

Detail and imaging seekers who want a resolving, technical set with a deep sub-bass lift rather than a warm mid-bass
Vocal lovers — especially of female vocals — who want clean, clear, forward voices
Listeners sensitive to 3–8 kHz glare who still want a crisp, detailed top end (with the right tips)
People willing to tip-roll (or add an O-ring) to get a deep, stable seal — that is where its bass and dynamics arrive
Anyone curious about the Elysian sound who can't stretch to the Diva, Gaea or Annihilator

Think twice if

You want a thick, warm, hard-hitting mid-bass — the low end is sub-bass-first and several call it lean
You want an exciting, colourful 'wow' tune — a sizeable camp finds it safe, dry or boring
Your ears don't suit short or wide nozzles — the fit and seal are the most common owner complaint
You swap cables often or baby nothing — Pentaconn Ear cables are scarce, and the polished faceplate scratches easily
You're value-shopping at full $400 — several critics rate it closer to a $200–300 set against today's rivals

6 / 12topics divide opinion

6 Mostly agree6 Divided opinions

Common ground7

Class-leading sub-bass extension and rumble — deep, textured and fast; every measurement rig shows it sitting well above the mid-bass.
Highly resolving for the price, with precise imaging and easy separation.
A clean, clear midrange with vocals (especially female) as a highlight — lean in the lower mids.
A wide, open stage for an IEM, though front-to-back depth is shallow.
A coherent, neutral-leaning tune that is safer and less intense than Elysian's flagship house sound.
A premium metal build and an excellent stock cable — offset by a scratch-prone polished faceplate and scarce Pentaconn Ear cables.
Easy to drive (9 Ω) but sensitive to seal, tips and source: a higher-impedance source adds bass, and a poor seal takes it away.

Points of contention6

Bass: a lean mid-bass and modest quantity vs a big, punchy low end — largely a matter of seal.
Treble: smooth, controlled and non-fatiguing (some say short on air) vs bright and energetic, occasionally hot or sibilant on the wrong tips or source.
Dynamics: blunted and 'too safe' vs weighty and lively once it seals.
Fit: light and comfortable vs a short, wide nozzle that won't hold a seal or a sharp faceplate edge.
Isolation: better than expected vs average-to-below for a heavily vented shell.
Value: a lot of Elysian for the money vs a brand-name premium in a crowded $400 bracket.

A balanced, neutral-leaning signature with a sub-bass lift — tuned safer and more mid-centric than Elysian's flagship house sound. Reviewers agree it is coherent and clean but reach for different labels (neutral and mid-centric, W-shaped, mildly U- or V-shaped, 'neutral-bright'), which reflects both its unusual shape — an early ear gain and a relaxed upper midrange — and how much it moves with tips and seal.

“safer with tonality and thus misses out on the Elysian U-shaped house sound many adore”
VSG, TechPowerUp

“very neutral and mid-centric tuning”
Nealz, mobileaudiophile.com

“the Pilgrim maintains the Elysian w-shaped sound signature”
Berkhan, Headfonia

“The Pilgrim is more of a forward tuning, without becoming overly bright”
Acho, achoreviews.com

Measured

Thirty-seven squig.link rigs (36 IEC-711-class, one B&K 5128) agree to within about a decibel up to 4 kHz: a sub-bass shelf about +9 dB at 20 Hz that is flat by 200 Hz, an early ear-gain peak at 2.5–2.7 kHz (~+7 dB, 3–6 dB under the Harman IE 2019 target through 4 kHz), a presence peak near 4.7 kHz and a band 4.6–5.9 dB under target from 5.5 to 7 kHz. headphones.com's own 711 graph reads the same shape as 'a pronounced 1.5 kHz hump and significantly relaxed 3 - 4 kHz region'.

Band: opinion spread · Dot: weighted average

Sources split: a majority hear a smooth, controlled, non-fatiguing top end — a few wishing for more air and sparkle — while a sizeable minority hear it as bright and energetic, a thrill to some and hot, grainy or sibilant for others on the wrong tips or source. The rigs show why both are right: a real presence peak near 4.7 kHz, then a relaxed 5.5–7 kHz band and a polite 10 kHz. The retail tune is also tamer than the pre-production unit shown at CanJam, which two critics miss.

Measured

Every rig shows a presence peak at 4.6–4.8 kHz (median +6.7 dB re 500 Hz), followed by a band 4.6–5.9 dB under Harman from 5.5 to 7 kHz and ~2 dB under at 10 kHz. Rigs diverge by 6–8 dB above 8 kHz, and tip swaps alone move the 8–10 kHz octave by 2–5 dB. Super* Review's CanJam NYC 2024 pre-production trace is about 3 dB hotter at 6–8 kHz and 5 dB hotter at 12–15 kHz than his retail sample.

vs. listeners — The graph supports both camps at once: the 4.7 kHz peak supplies the 'bite' and 'brightness' the second camp reacts to (and wide-bore tips, a shallow seal or a bright source push it forward), while the dip behind it and the modest 10 kHz are why most hear it as smooth and some as short on air. Critics who heard the prototype call the retail tune 'nerfed'.

Where it splits

Smooth, controlled and non-fatiguing — well extended but polite, with some finding it short on air and sparkle.55%

“It handles complex tracks well enough and is not going to be fatiguing, but that also means the Pilgrim misses out on the sparkle and air in the treble”
VSG, TechPowerUp

Bright and energetic — plenty of air and bite, exciting to some, hot or fatiguing to others depending on tips and source.45%

“a strong brilliance region spike gives the Pilgrim plenty of air and shimmer but at the expense of listening fatigue”
Thomas, Headfonics

What to keep in mind 6

This is a read of where opinion sits as of September 2026, two years after launch; the sub-$400 IEM field has moved a lot since, and newer rivals keep shifting the value math.
How the bass, dynamics and treble land depends heavily on fit: the nozzle is short and wide, and a shallow or broken seal makes it sound lean and dry, so your experience may differ from any single impression.
Tips and source matter more than usual. Tip changes mostly move the top octave, while a source with higher output impedance measurably adds bass — pair it thoughtfully.
The retail tuning is a little tamer than the pre-production unit some reviewers first heard at shows, so early show impressions may not match what ships.
Most enthusiast reviews came from loaned tour units; owner ratings are few and skew toward people who chose to buy it, and Head-Fi's member scores (4.3 of 5) are an enthusiast set rather than a random sample.
Measurement rigs agree closely up to about 4 kHz but read the upper treble quite differently, so treat any single graph's top octave with care.
