Babe wake up, SERAPHIM just DROPPED

ZiiGaat x Jay Audio Seraphim — Review Summary

Sound and tuning

• Designed as a clear, dynamic, textured all-rounder, aiming to combine musical impact and contrast with natural timbre and flagship-level finesse.
• Carries over some of the Storm’s clear, textured treble, while smoothing its peaks to reduce brightness and fatigue. It also adds more low-end dynamics.
• Bass is intended to be punchy, rumbly, and impactful, while remaining clean and distinct from the mids.
• The frequency response includes a deliberate dip around 300 Hz. The reviewer says it helps preserve clarity, air, separation, and texture. More bass below that region and added lower mids above 500 Hz are intended to keep drums and sub-bass impactful, and male vocals natural rather than thin.
• Upper mids are restrained from roughly 2–8 kHz to reduce vocal shout and fatigue. Smoother treble peaks, along with added air and extension, are intended to keep the sound open and detailed without excessive brightness.
• Vocals and bass are described as fairly balanced, with a slight emphasis toward sub-bass. The reviewer particularly recommends the Seraphim for female vocals.
• Male vocals sound natural but are not especially thick, husky, or warm.
• The reviewer intends the IEM to work well across genres while retaining a distinctive, engaging character. Their listening target was around 75 dB, depending on the track and listener, for long-term hearing health.

Design, drivers, and comfort

• Uses a dual PLT dynamic-driver isobaric bass setup and three Knowles balanced-armature drivers for mids and highs. The reviewer credits the Knowles drivers with reliable quality control, detail, and characteristic texture and timbre.
• Larger vents create a semi-open-back design, intended to reduce pressure buildup and the congested, “in-your-head” sensation while providing a greater sense of space.
• The aluminum faceplate’s curved design is described as resembling an angel’s wing, matching the Seraphim name. The reviewer considers it ZiiGaat’s best-looking IEM to date.
• Includes a silver cable described as sturdy, lightweight, comfortable, and easy to wear. The reviewer prefers its thinner, lighter construction.
• The reviewer plans to hand-sign up to 2,000 units, as many as they can manage.

Tips and sound adjustments

The reviewer says tip choice makes the Seraphim adaptable:

• Stock black and clear ZiiGaat tips: balanced sound.
• Divinus Velvet regular: more bass.
• Tangzu Senkai (regular or wide) or Kiwi Ears Flow: smoother sound.
• Softears Ultra Clear Titanium or Tri-Clear: more upper mids, treble air, and extension.
• AZLA SednaEarfit XELASTEC: smooths the upper mids for a particularly smooth presentation, but reduces some texture.

Comparisons

• Storm: The Seraphim aims to retain the Storm’s clear, textured treble while making it smoother and less in-your-face, and adding more low-end dynamics.
• Estrela: The Estrela is the brighter, more aggressive, and more colorful choice, with deeper rumble and more treble energy and air. The Seraphim is more balanced and natural while retaining clarity and texture. The reviewer still considers the Estrela a strong technical IEM in the under-$300–$400 range, but personally leans toward the Seraphim, including for its appearance.
• Variations: The reviewer uses its mid-bass scoop to explain why a dip can be problematic when there is insufficient mid-bass. They argue that the Seraphim’s bass quantity and lower-mid tuning avoid that issue.
• Harman 2019 target: The Seraphim is described as having a gradual vocal rise from around 500 Hz to 3 kHz rather than following that target.

Pros and limitations

Pros

• Clear, textured presentation with punchy, separated bass.
• More controlled, less fatiguing treble than the Storm.
• Natural vocal timbre and particularly pleasing female vocals.
• Semi-open vents intended to improve comfort and perceived space.
• Attractive design, lightweight cable, and flexibility through tip rolling.

Limitations

• Its 300 Hz scoop may look concerning to some listeners, though the reviewer considers it intentional and beneficial.
• Male vocals are natural but not especially thick or warm.
• The softened upper mids and treble may not suit listeners seeking a brighter, more aggressive presentation; the reviewer suggests the Estrela for that preference.
• The reviewer emphasizes that the tuning is subjective and may not suit everyone.

Verdict

The reviewer’s overall view is strongly positive: the Seraphim is presented as a polished, natural-sounding all-rounder that pairs textured clarity with engaging bass and smoother treble. It may suit listeners who want balance and detail without the Storm’s more prominent treble peaks, especially fans of female vocals. No numerical score or price is given.

Reviewer’s stated future plan

The reviewer describes the Seraphim as a “forever improving” IEM and plans to use community feedback and EQ suggestions to inform a possible future revision. All product impressions and comparisons above come from the single reviewer/designer; no other speakers provide a separate assessment.
