Great Clarity, exceedingly tip sensitive. Jaytiss Youtube Channel
Beautiful timbre and treble Bass can use a bit more...volume Tim Tuned Youtube Channel
Smooth, detailed, and vocal-centric sound. Cohesive, vocal-focused tuning with dynamic bass, smooth extended treble, and excellent detail. Could use more sub-bass.Gizaudio Axel original ranking

Just buy Fission. A cleaner/less warm LM, smoother EA1000 (fermats a little more resolving), very balanced, clean, and neutral sound. Very tough competition. Jays Audio Youtube Channel
One of the more balanced sounding Tanchjim iems, vocal centric Quantity in the bass region, more noticeably the subbass
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. Previously Owned
Japanese flavor of tuning (mid-bass and upper-mid focus) finally done justice. Strong technical chops and slightly forward. Precogvision Youtube Channel
Kiwi Ears Septet Reviews
Bright-leaning with slight warmness - has an unique sparkly/lush, airy, and spacious sound. Great tech for the price, treble is not overly harsh or peaky (at mid volume), pretty smooth with the extra mid-bass balancing out the treble boost. Vocals are pushed back/not fully extended and not as prominent. Mid-volume set, doesn't scale well. Gets spicy with energetic genres past mid-volume. Great for instrumentals, acoustics, indie, classical, etc. Jays Audio Youtube Channel
A unique open back iem. Jaytiss Youtube Channel

The Kiwi Ears Septet delivers a neutral-bright sound signature characterized by clear vocals and a notably forward treble that enhances detail retrieval, particularly in female vocals and acoustic instruments. Its bass response is neutral and controlled, lacking the weight of closed-back designs but offering tight, fast decay. While this tuning excels with well-recorded tracks, it can become fatiguing with bright or poorly mastered material due to its upper-midrange and treble emphasis. The open-back design contributes to an airy presentation, though it reduces isolation significantly.
Technically, the Septet showcases a wide soundstage with precise imaging and strong microdynamics, allowing subtle instrumental textures to shine. Its seven-driver quadbrid configuration (dynamic, balanced armature, planar, and piezoelectric) integrates cohesively through a sophisticated 5-way crossover. However, the low sensitivity (95dB) demands powerful sources to avoid dynamic compression, and the open-back design makes it less suitable for noisy environments despite its comfortable fit.
