The 1More SonoFlow HC905s is an over-ear ANC wireless headphone, a refresh of the original SonoFlow HC905, with 40 mm dynamic drivers and hybrid active noise cancelling in a closed-back design. Commuters, travelers and open-office workers get quieter, cable-free listening suited to long sessions.
Who the 1More SonoFlow HC905s is for
Commuters and flyers: Hybrid ANC takes the edge off engine rumble on trains and planes, so music and podcasts don't have to compete with it.
Open-office workers: Steady background hum such as HVAC is reduced, so music is easier to focus on, and with no cable there is nothing to snag on the desk.
Long listening sessions: Over-ear cups surround the ear rather than pressing on it, a fit suited to extended wear.
Skip it if: you need flagship-grade noise cancelling: the HC905-family ANC handles airplane rumble and HVAC hum well, but voices and clatter still get through.
