Same generation

THIEAUDIO Monarch MKIV (2025) against Ice Lab Spectrumica (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.
