Generation & platform
The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?
Same generation
The Kiwi Ears Belle is 5 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price. For 5 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said
HZSOUND HEART MIRROR
The HZSOUND Heart Mirror is a budget-friendly wired IEM that delivers a neutral-bright sound signature, prioritizing vocal clarity and natural timbre over booming bass. It offers solid build quality and a mature, reference-leaning tuning that appeals to listeners wanting a balanced, monitoring-style experience rather than a V-shaped, fun-oriented response. The main drawback is that achieving an optimal fit and seal may require experimenting with different ear tips. Overall, it stands out as a strong value pick for those who favor clean, articulate sound over bass-heavy presentation.
- Pro:Clear and articulate vocal reproduction
- Pro:Natural timbre with a clean, balanced presentation
- Pro:Excellent value for a reference-style tuning
- Con:Fit and seal can be finicky, needing tip rolling
- Con:Not for bass lovers seeking a fun, V-shaped sound
- Con:Neutral-bright tuning may come off as lean to some listeners
Kiwi Ears Belle
The Kiwi Ears Belle is a budget-friendly wired IEM that prioritizes a warm, bass-rich, and vocal-forward sound signature over analytical precision. It offers a comfortable, compact fit and solid build quality, making it a low-risk pick for everyday listening, though it trades some treble detail for a smooth, forgiving presentation. Its performance and included accessories make it feel more premium than its modest price suggests.
- Pro:Warm, engaging bass response
- Pro:Clean and vocal-forward midrange
- Pro:Comfortable, compact shell for long sessions
- Con:Treble extension is restrained, limiting air and sparkle
- Con:Soundstage depth and layering are only average
- Con:Not for listeners seeking high detail or analytical tuning
