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
Sivga SV351 (2024) against HiFiMAN HE 1000 Stealth (2023). These are 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.

What reviewers said
HiFiMAN HE 1000 Stealth
The HiFiMAN HE 1000 Stealth is a wired, open-back planar magnetic flagship that delivers a neutral, highly detailed sound signature. It's easier to drive than typical planars thanks to its 32-ohm impedance and 93 dB sensitivity, yet still rewards quality amplification. With its relatively lightweight build for a large headphone and detachable balanced cable, it offers strong technical performance and comfort, though its size and price may not suit everyone.
- Pro:Refined, neutral sound with excellent detail
- Pro:Easier to drive than most planar headphones
- Pro:Comfortable for its large over-ear design
- Con:Still relatively heavy at 458 grams
- Con:Large fit may be awkward for smaller heads
