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
Letshuoer S12 Ultra (2025) against TinHifi T5S (2024). 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
Letshuoer S12 Ultra
The Letshuoer S12 Ultra is a wired in-ear monitor built around a single 14.8mm planar magnetic driver housed in a lightweight aluminum shell. It delivers the signature planar sound of the S12 line—fast, detailed, and punchy—in a refreshed design aimed at hi-fi enthusiasts. With a low 16-ohm impedance, it pairs easily with most sources, though it lacks any active noise cancellation.
- Pro:Fast, detailed planar sound with strong dynamics
- Pro:Lightweight and sturdy aluminum-alloy build
- Pro:Easy to drive thanks to low impedance
- Con:No noise cancellation or isolation features
- Con:Planar timbre may not suit all listeners
- Con:Cable and accessories are basic for the price
TinHifi T5S
The TIN HiFi T5S is a wired in-ear monitor centered around a newly engineered dynamic driver with an ultra-linear diaphragm, aimed at delivering accurate, high-fidelity sound. It uses a standard 0.78mm two-pin connector and focuses purely on passive listening without any noise-canceling features.
- Pro:High-resolution dynamic driver for detailed sound
- Pro:Neutral, linear tuning suits critical listening
- Pro:Standard 2-pin cable offers easy aftermarket upgrades
- Con:No noise cancellation, so isolation depends on tips
- Con:Requires a wired source, no Bluetooth option
- Con:May lack bass punch for those who prefer warmer sound
