Generation & platform

Same generation

Letshuoer S12 Ultra (2025) against DUNU KIMA 2 (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.
