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 Sivga Lyrebird is 4 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 4 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said

HZSOUND Heart Mirror Pro

This wired IEM features a single 10 mm carbon nanotube dynamic driver and a detachable 0.78 mm 2-pin cable, housed in a compact shell. It delivers a warm, bass-forward sound signature, making it a more consumer-friendly tuning than its predecessor, ideal for casual listening across genres.

Pro:Warm, engaging bass response
Pro:Detachable standard 2-pin cable
Pro:Compact and comfortable fit

Con:No noise cancellation
Con:Bass may overpower detail for some

Sivga Lyrebird

The Sivga Lyrebird is a wired quad-driver hybrid IEM that impresses with its detailed, energetic sound, wide soundstage, and comfortable, well-built design, making it a strong option for audiophiles and gamers alike. However, its 4.4mm balanced connection requires an adapter or dedicated amp for most users, and its tuning may not suit heavier music genres. Despite a few technical caveats, it offers excellent separation, smooth treble, and solid value at its price point.

Pro:Excellent sound separation and imaging
Pro:Comfortable, premium build quality
Pro:Wide soundstage with smooth treble

Con:4.4mm balanced plug limits compatibility
Con:Needs a capable amp or adapter to sound best
Con:Sub-bass depth could be stronger
