Binary Dynaquattro Reviews
It has great tuning, but lack serverly in some areas. Very fun. Jaytiss Youtube Channel
Shines when driven properly. Excellent bass, vocal-forward tuning, and natural timbre. Hard to drive, could use more treble extension.Gizaudio Axel original ranking

Natural vocals, good treble extension, bass is tight and more resolving vs 61t and Davinci. Overall very well balanced and clean. There are some small peaks at 8-10k and 15-20K which can be an issue on some songs, and there is masking around 4-8k region, but overall, solid all-rounder. Jays Audio 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.
