True wireless earbuds for everyday listening

The kurdene S8-V9I are true wireless earbuds built for music and calls. Weighing 3.8g each, they sit inside the ear canal with three sizes of silicone tips. Bluetooth 5.3 handles the connection to iOS and Android devices. A charging case stores and powers the buds between uses.

Bluetooth 5.3 range and battery limits

The wireless link works up to 10m in open space. Each charge gives 4.5 hours of playback, and the case adds enough reserve for roughly 30 hours total. Recharging the case takes about 1 hours from a standard 5V USB source. Fast chargers are not required and should be avoided.

10mm drivers set the sound signature

A 10mm dynamic driver in each bud produces a frequency response of 20Hz-20KHz at 16 ohms impedance. The manufacturer highlights boosted bass output from the driver size. Buyers who want a neutral reference tuning or larger soundstage may prefer a different acoustic design.
