Built for Active Listeners

Kurdene S8 Pro in-ear earbuds weigh 3.8 g and use Bluetooth 5.3 for a stable wireless link. The ergonomic shape, tested on 1,000+ ears, stays secure during sports, gym sessions or daily commutes. Three silicone tip sizes help seal out ambient noise for immersive audio.

10 mm Drivers Deliver Deep Bass

Oversized 10 mm drivers produce powerful low-end response while maintaining 16 Ω impedance and 40 dB sensitivity. Sound-isolation ear coupling blocks external sound so bass detail remains clear without raising volume. The result is a balanced signature suited to bass-heavy playlists and podcasts alike.

Four-and-a-Half Hours of Continuous Play

Each charge provides 4.5 hours of operating time at typical listening levels. The case recharges the buds in 1 hour using a standard 5 V USB source. Touch controls keep interaction light so the fit stays comfortable through extended workouts or long calls.

Questions about this item

How loud will the 40 dB sensitivity sound with a typical phone output?

The 40 dB sensitivity means the earbuds reach moderate volume from a standard phone jack; you will not need maximum phone volume for comfortable listening.

What does Bluetooth 5.3 actually limit in daily use?

Bluetooth 5.3 caps the connection to the standard Bluetooth audio bit-rate and range; it does not add proprietary codecs or extend range beyond the specification.

Will the 3.8 g weight and 10 mm driver fit small ears without falling out?

At 3.8 g each bud is very light, and the 10 mm driver sits in a compact shell; three silicone tip sizes are included to seal different ear canals securely.
