What these earbuds are

No Sew Mi 1 in-ear earbuds in blue use a 13 mm dynamic driver and Bluetooth 5.3 to deliver wireless stereo sound for children and adults who want a lightweight daily pair. The set includes a charging case, a USB-C cable and a user guide in a single retail box.

When the 36-hour case makes the difference

Each earbud runs for up to 6 hours on its own charge and the case adds roughly 30 more hours for a combined 36 hours of playback before you need to plug in. The case itself refills in 1.5 hours, so the jump from a single-charge pair is worth it if you regularly spend long days away from a power socket.

Check these points before ordering

The earbuds weigh 0.091 kg total and use an in-ear fit with silicone tips; verify that this style suits the intended wearer’s ears. Connection is Bluetooth 5.3 only — there is no wired jack — so confirm the source device supports that version. The touch controls handle playback and calls; no companion app is mentioned in the supplied data.
