What reviewers said
KZ ZVX Pro
The KZ ZVX Pro is a budget-friendly wired IEM built with a sturdy all-metal shell and a detachable cable for easy upgrades. It delivers punchy, textured bass with solid extension, along with good imaging and soundstage for its price, though its tuning leans slightly away from neutral and has a notable peak around 8 kHz. Passive isolation is just average, making it less ideal for noisy environments.

- Pro:Good imaging and soundstage for the price
- Pro:Durable all-metal construction
- Con:Minor 8 kHz peak can add brightness
- Con:Tuning is not perfectly neutral

Sivga SM100
The Sivga SM100 is a budget-friendly single-dynamic-driver IEM that punches above its price class with an open, cohesive sound signature. It delivers impressive detail retrieval and well-controlled bass for the cost, though it does compromise on sub-bass depth and top-end airiness. Overall, it's a solid pick for listeners who value clarity and balance over extreme extension.

- Pro:Balanced, cohesive tuning with controlled bass
- Pro:Lightweight and comfortable with detachable cable
- Con:Sub-bass extension is limited
- Con:Treble rolls off noticeably in the upper frequencies
