No Sew B15 Open-Ear Headphones Bluetooth 5.4 40H Black

Open-Ear Design & Bluetooth 5.4

These headphones use an open-ear architecture that rests outside the ear canal, eliminating pressure and heat buildup. Bluetooth 5.4 provides a stable wireless link up to 15 meters with fast auto-pairing. The 90 ohm impedance and 98 decibel sensitivity combine with active noise cancellation for clear audio in office or outdoor settings.

Suited for Awareness, Not Isolation

The open fit keeps you aware of traffic, colleagues or announcements while you listen, making it a good match for commuters, office workers and runners. Buyers who need full passive isolation for loud environments or critical studio monitoring should look at closed-back or in-ear alternatives instead.

40-Hour Total Playtime with Fast Top-Up

The buds deliver 8 hours of continuous use per charge, and the case extends total listening to 40 hours. A 10-minute USB-C charge adds roughly 1 hour of runtime, so short breaks keep you going through a work week. Heavy users who exceed 8 hours between case charges will need to plan recharge intervals.
