**Notes on Buds 2a alternative**: The Buds 2a offers similar core experience at a lower price point (~$29–$39) with 12.4mm driver, ~42dB ANC, and ~35 hours total battery, but fewer mics, no LDAC or in-ear detection, and slightly less refined ANC/sound per reviews. It suits ultra-budget buyers but has fewer long-term reports.
