By aspect — in detail
Broadly agreed to be tuned accurately to the Harman 2018 over-ear target — a neutral, reference-leaning balance that most call natural and versatile, with a slight lift of energy up top that makes the E3 a touch brighter and livelier than dead-neutral (and than the pricier STEALTH). Measurements corroborate the target; the main nuance is that the treble tilt is exactly what the treble camps below argue about.
“E3 follows in the footsteps of Stealth and Expanse with a tuning that sticks close to the classic Harman Target.”
Bloom Audio
“The headphone sounds accurate while being very enjoyable.”
Audio Science Review (amirm)
Measured
Voiced to the Harman 2018 over-ear target: ASR found it “complies a bit better than Stealth” and TechPowerUp used the full Harman 2018 target as its reference. The E3 presents a flat ~27 Ω / ~90 dB/mW load, so source impedance won't shift the response. kuulokenurkka notes the E3 “deviates slightly” from the pair's near-perfect balance “by adding a touch of energy and liveliness to the reproduction with its brighter high frequencies.”
A genuine fault line — over quantity, not quality. Nearly everyone agrees the low end is tight, textured, fast and well-controlled. They split on whether there's enough of it: one camp hears class-leading, actually-dynamic closed-back bass (TechPowerUp even finds the sub-bass shelf a shade much); another hears it as rounded and modest next to dynamic headphones, light on slam and rumble, and dependent on a perfect seal or a little EQ. Not a basshead's headphone out of the box.
Measured
The Harman bass shelf is there on the graph — TechPowerUp thought the sub-bass “might be a bit too much,” while kuulokenurkka concedes “the low frequencies can sometimes sound a bit light compared to dynamic headphone models.” The split tracks something physical: an owner in the official thread reports “the lack of bass and some bass distortion when EQ'd,” and DCA itself says the E3's AMTS was retuned to “reduce sensitivity to seal for a more consistent bass experience” — so how much bass you get depends on fit and, for some, a small bass shelf in EQ.
Where it splits
Tight, textured and genuinely dynamic — even class-leading for a closed-back.60%
“The E3 does bass better than any other closed-back set I've listened to date. It is accurate, it is engaging, and it is also actually dynamic too.”
TechPowerUp (VSG)
Modest in quantity and slam — rounded and light next to dynamics, seal-/EQ-dependent.40%
“If you like powerful bass, then you are not in the right place here.”

A quiet strength almost no one disputes. The midrange is repeatedly called natural, detailed and well-articulated, with vocals cleanly placed and busy passages staying uncongested. The only recurring caveat is that the brighter top end can push some female vocals or upper harmonics forward for sensitive listeners.
“Both headphones reproduce mid-frequencies extremely naturally and faithfully to recordings.”
kuulokenurkka
“A great amount of midrange detail comes across as incredibly lush and expressive through the E3.”
MajorHiFi (Alex Schiffer)
Measured
headphonecheck found the mids “very perceptible and differentiated,” revealing detail other headphones conceal; kuulokenurkka notes the flip side of the brighter tuning is that “aggressive” or sharply produced female vocals can occasionally sound a touch unpleasant.
The central argument, and a physical one. Measurements show an elevated upper treble (a 6 kHz peak and extra air), so nearly everyone hears the E3 as leaning bright — but they split on whether that reads as a smooth, refined, 'correctly bright' top end or as a peak that can turn peaky, metallic or fatiguing. The tell is that ear-pad position matters enormously: owners report that shifting the cups down and forward drops the treble by several dB and transforms it, so seating and individual ear shape make the same headphone land very differently.
Measured
The elevation is real: TechPowerUp measured “a 6 kHz peak” plus added air at 12–13 kHz, and both ASR and kuulokenurkka hear the E3 as a bit brighter than the STEALTH. But TechPowerUp also flags that the “sound presentation can be quite dependent on ear pad positioning,” and an owner confirmed it dramatically — moving the cups down and forward “can reduce treble response by 3-5 db” and, in their words, made “all the unpleasant sibilance” go away.
⚠ vs. listeners — The upper-treble lift is measured and consistent, but whether it fatigues is highly variable — the same tuning is “almost perfectly smooth” to one reviewer and a 12–13 kHz presence that “kept irking” another, a divide most attribute to ear-pad seating and individual HRTF rather than to unit variation.
Where it splits
Smooth, refined and 'correctly bright' — clean and non-fatiguing.60%
“both headphones offer almost perfectly smooth and coherent treble reproduction, which many other manufacturers can only dream of”
kuulokenurkka
A lift that can read peaky or metallic — overly emphasized for some.40%
“Upper mids and air region may come off overly emphasized for some”

Soundstage
Strong consensus · 8 srcThe most agreed-upon strength, and unusually so for a closed-back. Across editorial, measurement and community sources the E3 is described as open, wide, spacious and three-dimensional — several reviewers say it sounds more like an open-back than a sealed one, and it's repeatedly named among the best closed-back stages available. No real dissent.
“E3 surpasses expectations for a closed-back headphone in the width and height of the stage.”
Bloom Audio
“The soundstage was vast and three-dimensional.”
Enjoy the Music (Gary Alan Barker)
Measured
There's no stage 'measurement,' but the read is near-universal: TechPowerUp calls it “a soundstage rivaling some open-back sets in depth and height,” Headfonics “more spacious sounding than any regular closed-back planar,” and MajorHiFi “one of the best closed-back soundstages you can get.” The AMTS-plus-sealed-cup design is credited for the open presentation.
Rated a strength, with a nuance. Most reviewers hear precise placement and clean separation within that big stage, and the excellent channel matching underwrites it. The one recurring caveat is that a couple of listeners find the image slightly diffuse — immersive and enveloping rather than pinpoint.
“The E3 also has precise imaging in a wide cone in front of your head”
TechPowerUp (VSG)
“You don’t get precise positioning, but the sonic environment does a phenomenal job of immersing you in its layered performance anyway.”
MajorHiFi (Alex Schiffer)
Measured
TechPowerUp's channel matching “easily exceeds the industry standard of +/-3 dB variance,” which helps place instruments precisely; Bloom Audio agrees the image is “well constructed, with a great sense of position and separation,” while noting instruments can be “somewhat diffuse.”
Detail
Strong consensus · 6 srcConsistently praised. Reviewers call the E3 highly resolving and transparent — fine detail is easy to hear, textures come through cleanly, and it's frequently floated as a mixing/mastering-capable tool. One of the least-disputed technical strengths.
“The detail was exquisite and palpable.”
Enjoy the Music (Gary Alan Barker)
“excellent detail retrieval”
TechPowerUp (VSG)
Measured
ASR measured “some distortion at low frequencies” that “quiets down quite well,” with distortion “very low where our hearing is most sensitive (2 to 5 kHz)” and “very clean” group delay — a clean measured basis for the resolution reviewers hear.
Mostly a strength, with one measured caveat. Reviewers hear real speed, punch and macro-dynamic swing — one likens the lower-register articulation to electrostatics. The dissent is that the E3 has limited headroom: one measured review found it best at quiet-to-moderate levels because it can distort when pushed loud, which lines up with the reports of distortion under heavy bass EQ.
“The speed and articulation, especially in the lower registers really do rival electrostatic headphones.”
Enjoy the Music (Gary Alan Barker)
“In terms of dynamics, the E3 were more for quiet to moderate listening.”
headphonecheck.com (Carsten Kaiser)
Measured
headphonecheck measured a low max SPL (91.15 dB, “among the quieter models available”) and noted that above a moderate level the E3 “could lead to distortion that is widely distributed across the frequency spectrum”; that ceiling, plus an owner's “bass distortion when EQ'd,” is the physical basis for the split — driven cleanly and not overloaded, most hear it as highly dynamic.
Comfort
Strong consensus · 7 srcA near-unanimous strength. Large, deep cups, soft pads and good weight distribution let most reviewers wear the E3 for hours — several rank it among the most comfortable closed-backs they've used. The caveats are minor: at ~455 g it isn't featherweight, DCA deliberately raised the clamp over older models (measured contact pressure is fairly high, though the pads mask it), and a couple of listeners feel the clamp on the jaw after a couple of hours.
“These approach the Meze ELITE in how comfortable they are for me, which is saying something for a closed-back set.”
TechPowerUp (VSG)
“the E3 is a very comfortable headphone on the head with excellent pressure and weight distribution.”
Headfonics (Marcus)
Measured
About 455 g without the cable. headphonecheck measured a high average contact pressure (~793 g) but found the soft pads keep it “comfortable to wear even during longer listening sessions”; kuulokenurkka, who welcomes the firmer clamp, still notes the pads “start to feel a bit uncomfortable on the jawline after a couple of hours of use.”
Widely praised as premium and tightly made — a foldable metal chassis with Gorilla-Glass cup plates, quality pads and DCA's VIVO cable, packing into a compact case. The recurring gripe is cosmetic rather than structural: the glossy cup finish looks smart but scratches and shows fingerprints easily.
“excellent workmanship that makes a high-quality package thanks to the cable”
headphonecheck.com (Carsten Kaiser)
“It brings a gloss to the earcups makes the E3 stand out from every other headphone in this price range, but I can see it being easy to scratch if you’re not careful.”
MajorHiFi (Alex Schiffer)
Measured
A foldable metal build with Gorilla-Glass-plated cups and DCA's signature VIVO cable, packing into an included case at ~455 g; reviewers consistently rate the materials and assembly high, with the glossy finish the main practical caveat.
Isolation
Contested · 5 srcA real split for a sealed headphone. Most reviewers find the passive isolation decent to good (especially against lower-frequency noise), but one measured review found it surprisingly weak for a closed-back, and the ported design leaks audibly outward — so it's not the pick for a quiet commute or a shared room where leakage matters.
Measured
It's a ported closed-back: kuulokenurkka notes it “leak[s] sound outwards through these holes” enough that someone nearby could make out vocals, while TechPowerUp and Headfonics still found the inward isolation useful (Headfonics: better at “blocking lower-frequency background noise”). headphonecheck is the outlier that measured the overall isolation as surprisingly low.
Where it splits
Decent-to-good passive isolation for a closed-back.65%
“The closed-back isolation is quite significant across the entire frequency response.”
TechPowerUp (VSG)
Surprisingly weak isolation, and it leaks outward through the ports.35%
“Both the acoustic isolation from the outside and the attenuation of external noise were surprisingly low with these headphones, considering that they are a closed model.”
headphonecheck.com (Carsten Kaiser)
Mostly rated highly — several reviewers frame the E3 as flagship-grade sound and tech at roughly half the STEALTH's price, and one calls it outright the best value in headphones. But there's a real skeptical minority who find it hard to justify given its modest bass slam, limited loudness and distortion headroom — and the recent rise from the $1,999.99 launch price to $2,299.99 direct sharpens that objection.
Measured
Launched at $1,999.99 (the figure every review quotes; ASR framed it as “half of Stealth” and “even a more exciting development”) and now listed at $2,299.99 on Dan Clark Audio's store. A r/headphones owner captured the skeptic's view even at the lower price: “very hard to justify the $2000 asking price.”
Where it splits
Class-leading value — flagship tech and sound at roughly half the STEALTH's cost.70%
“There is nothing else in my collection here which comes remotely close to offering the E3's level of user experience for the money.”
TechPowerUp (VSG)
Hard to justify at the price given restrained volume and distortion.30%
“I was not entirely happy with the price-performance ratio due to its very restrained volume and the distortion that quickly occurred.”
