Ruth's sister TWS Bluetooth Earphone 9D Stereo V5.1 HiFi Earbud Sport

SKU CH-8YGJ-1X00C

True wireless earbuds with 10 m range, 3–4 h playtime and 40 min charge

  • Automatic pairing starts playback instantly when removed from case
  • LED digital display shows battery status at a glance
  • 10 m wireless range keeps connection stable during sport
  • 3 to 4 hours playtime supports extended workouts
  • ABS construction resists daily knocks and drops

What it is and who it suits

These true-wireless earbuds use a dynamic driver to deliver stereo sound with a frequency response of 8-25000 Hz. They pair automatically when removed from the charging case and include a smart LED display for battery status. The in-ear design targets sport and daily use.

Who should choose these and who should not

Buyers wanting automatic pairing, on-board volume and call controls, and a compact case measuring 12cm by 7.8cm by 3.5cm will find them practical. Users who need active noise cancellation or any waterproof rating should look elsewhere.

The spec that decides fit

The earbuds provide 3-4 hours of playback or talk time per charge, with the 260mAh case adding further cycles via a 40-minute recharge. If your sessions regularly exceed that window without a chance to top up, this set will not cover them.
