Yanyin Canon II

The most-praised part of the set by a wide margin: deep, textured and — the recurring word — controlled, elevated well above neutral without bleeding into the mids. A minority hears it as loose or pillowy rather than tight, and several reviewers who like it still warn it is more low end than some will want.

“The bass is well-controlled and textured, without any bleed or bloat.”

Meldrick, Headfonics

“There may be some voodoo magic happening here but the bass of the Canon II is just so rich, thick, and texture while keeping it clean enough to not intrude on the midrange.”

@kesobie, Head-Fi

“Pillowy bass response. Not the most well textured DD-bass.”

@DestinoAzell, Head-Fi

Broadly loved — rich, natural, with real note weight on both male and female vocals, and no sense of the bass swamping them. Reviewers place them differently (slightly recessed, dead centre, or the star of the show), and one careful listener hears an upper-midrange imbalance that reads as glare.

“And on the Canon 2 mids are absolutely marvelous.”

Headphonesty

“The midrange is neither forward, nor recessed.”

Yagiz, Headfonia

“I hear a slight imbalance toward upper midrange, leading to occasional glares and shoutiness.”

The single biggest disagreement about this set. Roughly half the field calls it safe, dark and short on air; a smaller group calls it crisp and well-extended; a third strand hears occasional grain or roughness. Everyone agrees it is not fatiguing.

The clearest point of agreement: warm, bass-elevated, and deliberately non-shouty. The labels vary — warm-neutral, slight U, slight V, dark — but every source lands on the same side of neutral, and nobody calls it bright or aggressive.

“Warm pleasant tonality, smooth and non-fatiguing”

@baskingshark, Head-Fi

“The Canon II has a warm-neutral signature with an emphasis on the sub-bass region.”

Yagiz, Headfonia

“The Blessing 3 has a neutral sound signature, while the Canon II has a more exciting, somewhat V-shaped sound signature.”

Meldrick, Headfonics

Genuinely split down the middle. One camp calls the stage wide and expansive for the money; the other calls it average in width and rather intimate. Notably, several in the second camp single out depth and front-to-back layering as the real strength.

Widely called a strength — precise placement, clean layering, instruments easy to pick out of a mix. The dissent is narrow but specific: one reviewer finds the notes cohere rather than separate, without the hard-edged definition he looks for.

“The imaging of the Canon II is precise and coherent, with good separation and layering.”

Meldrick, Headfonics

“Excellent technicalities, especially with regard to layering and imaging”

@baskingshark, Head-Fi

“the instruments do not pop out with laser sharp definition”

@o0genesis0o, Head-Fi

Contested, and the split is about price rather than sound. Most reviewers are surprised that a tuning this warm resolves as well as it does; a real minority says that once you stop grading on the warm-tuning curve, the resolution is ordinary for $379.

Mostly praised for slam and macro-dynamic swing — the bio-diaphragm driver hits hard and stops cleanly. One reviewer hears the opposite, describing the overall transient as soft.

“Very full and expressive macro-dynamics”

Chris Love, Mobileaudiophile

“Decay is short so it has good impact and slam but it sounds tight and strong.”

Corgifall, Audio Discourse

“Overall dynamic transient is soft.”

@DestinoAzell, Head-Fi

Overwhelmingly good — a smooth unibody shell that most reviewers wear for hours without noticing, one calling it the best-fitting set he had tried in years. The nozzle is on the long side, though, and at least one careful listener could not get it to seat without pressure build-up. Fit is the one variable worth reading twice on.

Split, and the shell design explains why: it is a vented hybrid, so it blocks a fair amount but leaks more than a sealed set. Reviewers grade that same behaviour as either excellent for a universal or unremarkable, depending on what they compare it against.

A one-piece medical-resin shell with a glitter faceplate that reviewers consistently rate above its price, and one of the better stock cables in the class. The switches need the supplied pin to flip. The only durability complaints come from buyers rather than reviewers, and they are few but pointed.

“Robust build, with beautiful resin shells”

@baskingshark, Head-Fi

“The craftsmanship is impeccable, with no evident flaws.”

Yagiz, Headfonia

“But unfortunately the left IEM died inside of a yr.”

Verified buyer, Linsoul

Positive on sound, and near-unanimously grumpy about what comes in the box. Reviewer after reviewer calls the $379 performance strong and the four pairs of tips, single non-modular cable and bare accessory set thin for the tier — it is the most repeated criticism of the entire set.

“the Canon 2 seems like a no-brainer for most listeners”

Headphonesty

“Great price to performance ratio”

Yagiz, Headfonia

“The accessories are very spartan for a midFI priced IEM, and this is disappointing.”
