Mid-forward, neutral-bass sound signature. Not very versatile across genres. Clean mids and forward vocals. Light bass impact, upper mids can get intense, and average detail.

The open back nature of this iem is compelling!

The TANCHJIM x Effect Audio Force employs a dual dynamic driver configuration, pairing a 10mm titanium-coated bass driver with an 8.2mm beryllium-coated mid-high driver. This setup, managed through Tanchjim's HPFD-Seg crossover technology, aims for cohesive integration, delivering impactful low-end while maintaining clarity in vocals and treble. The notable open-back design incorporates a pressure-relief nozzle to minimize listening fatigue, though isolation remains surprisingly effective despite the acoustic vents.

Tonally, the Force leans toward a balanced signature with a mild bass emphasis, avoiding excessive warmth while retaining texture in kick drums and basslines. Treble extension is smooth and non-fatiguing, though some may find airiness slightly reserved compared to brighter tunings. The standout inclusion is the Type-C DSP cable, enabling deep customization via Tanchjim's app—including parametric EQ and Harman target presets—which significantly refines the stock tuning for personal preference.

Technically, the open-back architecture contributes to an expansive soundstage with precise imaging, excelling in complex tracks where instrument separation matters. While dynamics are competent, micro-detail retrieval doesn’t quite match elite hybrid or EST-equipped IEMs in its price tier. The co-engineered Effect Audio cable and ergonomic resin shells ensure long-wearing comfort, rounding out a package that prioritizes refinement over raw resolution.

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.
