The Monster AC601 is a clip-on open-ear wireless earbud that hooks over the ear so the ear canal stays open. It uses Bluetooth 5.4, an ENC noise-canceling mic for calls, and Monster rates total playtime at 40 hours with fast charging. It suits runners, cyclists and commuters who want to hear traffic and surroundings, and it competes with open-ear clips like the Shokz OpenFit and Bose Ultra Open on comfort and awareness rather than bass or isolation. The 4.8 rating from 60 buyers is a small sample, so treat it as early signal.
