Should you buy it?
DUVA ONE are ultra-slim sleep earbuds at 3.3g each and 9.9mm thick, with 40-plus tip and wing options for side sleepers. Hybrid ANC rated up to 42dB blocks noise, and in-ear PPG and motion sensors track heart rate, HRV, movement and estimated sleep stages. Battery life is up to 16 hours, and the case supports wireless charging. They're new, so long-term comfort and app maturity are unproven.
Best for
Light sleepers who want noise blocking and sleep tracking in one
Not for
Listeners who want everyday music earbuds
