Open-Ear Design for Awareness

The No Sew Q77 open-ear headphones use air conduction technology to rest outside the ear canal. Each earbud weighs 6.9g and uses liquid silicone for a pressure-free fit. This design suits runners, office workers and anyone who must hear ambient sound while listening.

50-Hour Total Playtime with Case

A single charge provides 8 hours of continuous use and the LED charging case extends total playtime to 50 hours. USB-C fast charging reduces downtime between sessions. The 14.2mm racetrack drivers and composite diaphragm deliver balanced stereo output with passive noise cancellation throughout the day.

Check Bluetooth Version and Fit Preference

Verify that your source device supports Bluetooth 5.4 for stable pairing. The open-ear earhooks do not seal the canal, so buyers who want full isolation or in-ear tips should consider a different style. The package includes the earbuds, a charging case, a cable and a user manual.

Questions about this item

How much power does the Q77 draw during all-day listening sessions?

Each earbud runs for 8 hours on a single charge and the LED charging case extends total playtime to 50 hours, with USB-C fast charging to top up quickly between uses.

What does the Q77 need from my device to start playing audio?

A source that supports Bluetooth 5.4 is required; the earbuds have no wired jack and ship with a charging cable and LED case but no separate transmitter.

Will the open-ear design of the Q77 let me hear my older wired headphones if I keep them nearby?

The open-ear fit leaves the ear canal unblocked so ambient sound passes through naturally, allowing you to stay aware of surroundings while the Q77 plays.
