Audionotions 7 Reviewer Score
Yes, it's expensive for a single DD imaging and separation is top tier with very good layering - frankly, I haven't heard many sets near this price that have done the same. There is a bit of subbass roll off but midbass hits hard. It's on the brighter side but never becomes shouty or sibilant. Timbre is good with vocals a bit forward in the mix. Tuning nozzles are a gimmick - they all sound the same. A better Kato in every way. I had a lot of trouble with fit on with this set - did not have the same problem with Hana 2021.

Smooth, detailed, and vocal-centric sound. Cohesive, vocal-focused tuning with dynamic bass, smooth extended treble, and excellent detail. Could use more sub-bass.

Just buy Fission. A cleaner/less warm LM, smoother EA1000 (fermats a little more resolving), very balanced, clean, and neutral sound. Very tough competition.

Japanese flavor of tuning (mid-bass and upper-mid focus) finally done justice. Strong technical chops and slightly forward.

Average Technical Grade

A-

Bass is strong and well-defined, delivering slam with admirable control. Electronic drops hit with authority.
Mids A-
It delivers an excellent midrange that feels vibrant and true to life. It balances clarity with natural smoothness.
Treble A-
Highs feel superbly executed, revealing micro-detail without hint of sibilance. Highs stay smooth even at volume.
Dynamics B
The performance feels robust, with satisfying punch and natural transitions. Nuances are easy to follow.
Soundstage A-
The stage stretches in every direction, carving out clear three-dimensional pockets for each player. Placement accuracy impresses from the start.

Finer gestures snap into focus without sounding clinical or forced. Layering holds strong across genres.
Imaging B+

Average Technical & Tuning Grades

Average Tunign Grade

C+
  • Expect a friendly tonal balance that could use polish but remains inviting. Great for casual listening, less so for purists.

Average Technical Grade

C-
  • Even moderate complexity exposes the limited resolution and narrow sense of space. Technical fans will find it lacking.
Mids C+
Expect a competent midrange that keeps vocals grounded and instruments clear. Tone is acceptable across multiple genres.
Treble C-
The top end sounds acceptable but lacks the smoothness of higher tiers. Air is hinted at more than delivered.
Dynamics C+
It offers fair punch and contrast, though micro-dynamics could be sharper. Impact is satisfying for day-to-day use.
Soundstage C+
It pushes sound outward confidently while leaving height development as an unfinished idea. Height remains subtle but detectable.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.
