Less treble than the E4000 for a slightly different flavour.

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.

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.
