kurdene OWS9I open-ear headphones

The kurdene OWS9I-Black are open-ear Bluetooth 5.4 headphones that rest on top of the ears with soft silicone hooks. They suit runners, commuters and office workers who want situational awareness while listening. The 16.1 mm diaphragm drivers deliver deep bass, crisp mids and clear treble for music and calls.

12-hour battery and Bluetooth 5.4 link

Each charge provides 12 hours of continuous playtime and the case adds 48 hours for 60 hours total. Bluetooth 5.4 gives a stable connection up to 33 feet with faster data transfer. The headphones draw minimal power and produce no audible fan noise because they have no active cooling.

Touch controls and secure fit

Multifunction and volume touch zones on each earbud handle playback, calls and voice assistants without reaching for a phone. The open-ear coupling and ear hooks stay in place during workouts while leaving the ear canal open. Built-in microphones with 88 dB SNR isolate speech for clear calls in meetings or outdoors.

Questions about this item

How do I pair these Bluetooth 5.4 open-ear headphones, and what step do people often miss?

Enable Bluetooth on your device, open the charging case to enter pairing mode, then select "kurdene OWS9I" from the list; the step many miss is removing the protective film from the earbud charging contacts before the first use.

What maintenance will the 16.1 mm drivers and ear hooks need over time?

Wipe the open-ear drivers and silicone ear hooks with a dry, soft cloth after each workout to prevent sweat buildup; the case provides 48 hours of extra charge, so recharge it weekly to keep the 60-hour total playtime available.

Which limit appears first during a long run — battery, range, or heat?

The 12-hour single-charge battery limit arrives before the 10-meter Bluetooth range or thermal throttling; the charging case adds 48 hours for a 60-hour total.
