Wireless Earbuds with Bluetooth 6.0

These No Sew PC-02 earbuds use Bluetooth 6.0 with a Lanshun 5756C chipset for a stable connection up to 15 meters. The open-ear clip design keeps the ear canal unobstructed so users stay aware of their surroundings. Each bud weighs very little and the case shows remaining power on a digital display.

Suited for open-ear listening

Commuters, runners and office workers who want to hear ambient sound while taking calls or streaming audio will appreciate the MEMS microphone and dual-pairing support. Buyers who require active noise cancellation, a wired connection option or more than five hours of continuous playtime per charge should consider different designs.

Five-hour single-charge playback with 400 mAh case

Each earbud delivers up to five hours of playback at 70 % volume and the 400 mAh charging case provides 30-plus hours of total usage. This runtime figure is the key spec to check against daily listening habits before purchase.

Questions about this item

How do I choose between the earbuds and the charging case for battery life?

Each earbud gives up to 5 hours of playback at 70% volume. The 400 mAh case adds multiple full charges for a total of 30+ hours, and its digital display shows the remaining power.

What does the 5-hour playback figure mean in daily use?

At 70% volume you can expect about 5 hours per charge. The case recharges the earbuds several times, so you can go through a full day or more without plugging in.

What does Bluetooth 6.0 actually cap in practice?

The Bluetooth 6.0 link with the Lanshun 5756C chipset keeps a stable connection up to 15 metres and provides ultra-low power consumption for longer battery life.
