Open-Ear Bluetooth 5.4 Headphones

The kurdene OWS9I-Black are open-ear wireless headphones that rest on top of the ears instead of sealing the canal. They use Bluetooth 5.4 for a stable connection up to 10 metres and deliver audio through 16.1 mm diaphragm drivers with 32 ohm impedance and 88 dB sensitivity.

Suited for outdoor awareness, not isolation seekers

Runners, cyclists and commuters who need to hear traffic or announcements will benefit from the open design and 12-hour single-charge battery. The charging case adds 48 hours for 60 hours total. Buyers who want active noise cancellation or full bass immersion should look at closed-back or in-ear models instead.

Bluetooth 5.4 with 10-metre range

The headphones connect via Bluetooth 5.4 and maintain a reliable link up to 10 metres. This single spec decides whether the wireless freedom matches your phone, laptop or tablet usage.

Questions about this item

What does Bluetooth 5.4 limit in practice?

Bluetooth 5.4 provides a stable connection up to 10 metres or 33 feet with faster data transfer for audio and video sync.

What does the open-ear design need to fit securely?

Soft silicone ear hooks rest on top of the ears for a snug, pressure-free fit without entering the ear canal.

How are the headphones charged, and what step is often missed?

Place the earbuds in the included charging case; the case itself must be charged separately to provide the additional 48 hours of playtime.
