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 Letshuoer S12 Ultra is 6 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 6 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said

1MORE H1001

The 1MORE H1001 is a wired hybrid in-ear monitor that pairs a dynamic driver with two balanced armatures for a lively, V-shaped sound with pronounced bass. Its all-metal build, Kevlar-reinforced cable, and comfortable fit make it a durable choice, while the inline remote works with both Android and iOS devices. Though it was once a standout value around $100, newer models have since raised the bar in this price range.
