The 1More SonoFlow Pro HQ51 is a folding over-ear wireless ANC headphone rated for up to 100 hours with ANC off and 65 with it on, and it adds LDAC over Bluetooth 5.4 in a 246g build. It's for commuters and travelers who want hybrid noise cancelling and days of listening between charges.
Who the 1More SonoFlow Pro HQ51 is for
Commuters and frequent flyers: QuietMax hybrid ANC dulls transit chatter and traffic noise, and 1MORE rates it at up to 65 hours with ANC on.
Android phones with LDAC: LDAC is supported alongside AAC and SBC; an iPhone can't use LDAC and connects over AAC instead.
Laptop-and-phone multitaskers: Two-device connection keeps a laptop and a phone paired at the same time; switch it on in the app first.
Travelers who want a wired backup: A 2.5mm-to-3.5mm cable for wired listening and a hard carry case come in the box.
Skip it if: you need flagship-level noise cancelling or a premium build; reviewers place its ANC below flagship models, and the body is plastic.

1More SonoFlow Pro HQ51 vs similar options
vs 1More SonoFlow HC905: The original SonoFlow keeps LDAC and multipoint but is rated 70h with ANC off and 50h with it on, versus 100h and 65h here; pick it if you prefer a bassier tuning.
vs FiiO Snowsky Anytime: A lighter 155g on-ear with ANC, a transparency mode and a sub-60ms game mode, but no LDAC and up to 58h with ANC off; choose the HQ51 for over-ear isolation, LDAC and longer battery.
