The Pursuit of Neutrality and Detail

The 7Hz Salnotes Zero garnered significant attention for bringing a relatively balanced and detailed sound signature to the ultra-budget market. It utilizes a 10mm dynamic driver with a metal composite diaphragm, aiming for clarity and precision.

Sound Signature: Neutral-Bright Clarity

The Zero is often described as having a neutral-bright tuning. This means it strives for accuracy across the frequency spectrum but with a slight emphasis on the upper midrange and treble frequencies. This tuning can enhance the perception of detail, instrument separation, and airiness in recordings. Some reviewers note it offers a slightly wider soundstage compared to the Wan'er.

Frequency Breakdown

Bass: The bass response is generally considered clean and present but relatively lean or subdued. While it provides some warmth and avoids boominess, it lacks the deep sub-bass rumble and mid-bass impact that some listeners associate with a fully natural or engaging low-end. This makes it accurate for certain genres but potentially unsatisfying for bass-heavy music.
Mids: The midrange is clear and renders vocals and instruments with good detail. However, compared to warmer IEMs, it might sound slightly less full-bodied or emotionally engaging for some. Its neutrality here is a strength for monitoring but less so for relaxed listening compared to the Wan'er.
Treble: This is where the Zero can be divisive. It offers good extension and detail, contributing to its clarity. However, many reviews point out potential peaks in the upper treble region, leading to brightness, occasional sibilance (harsh 's' sounds), and listening fatigue for sensitive users or on poorly mastered tracks. This potential harshness detracts from a purely "natural" presentation for many.

Naturalness Assessment

The Zero's pursuit of neutrality can be interpreted as a form of naturalness, aiming for accurate reproduction. Its strength lies in clarity and detail retrieval at its price point. However, the lean bass and potentially sharp treble mean it might not sound "natural" in the sense of being effortlessly realistic or relaxing for extended periods. It's often better suited for analytical listening or specific genres where its clarity shines, rather than providing an organically warm, lifelike timbre across all music.

Sound Signature: Warm-Neutral Cohesion

The Wan'er 2 offers a warm-neutral sound signature. This implies a base of neutrality but with added warmth, particularly in the bass and lower midrange, creating a more inviting and smoother listening experience. It prioritizes balance and avoids sharp peaks, aiming for a sound that's easy to listen to for long sessions.

Frequency Breakdown

Bass: The bass is warmer and has more presence than the Zero, particularly in the mid-bass region. It provides a satisfying rumble and impact without becoming boomy or bleeding into the mids. This contributes to a fuller, more grounded sound that many find more natural and engaging for a wider variety of music genres.
Mids: This is widely regarded as the Wan'er 2's strongest suit. The midrange is forward, smooth, and excels at reproducing vocals (both male and female) and instruments with a natural, realistic timbre. Vocals sound intimate and clear without harshness, contributing significantly to its overall perceived naturalness.
Treble: The treble is present and offers sufficient detail but is notably smoother and better controlled than the Zero's. It avoids the sibilance and fatigue-inducing peaks that can plague the Zero, opting for a gentle roll-off that retains airiness without becoming harsh. This smoothness is key to its non-fatiguing, natural character.

Naturalness Assessment

The Tangzu Wan'er 2 generally scores higher in perceived naturalness for most listeners. Its combination of balanced warmth, excellent vocal timbre, smooth treble, and cohesive presentation creates a sound that is both engaging and easy on the ears. It mimics the pleasing tonality of live music or well-mastered studio recordings more effectively for relaxed listening, avoiding the analytical edge or potential harshness of the Zero. It's often described as sounding "right" or organic.
