Open-ear clip design for awareness

The DUCOCUB Auro 3 uses an open-ear clip form factor that rests on the ear without sealing the canal. This keeps the wearer aware of ambient sound while delivering audio. The 14.2 millimetre driver unit produces a frequency response up to 20000 hertz at 32 ohms impedance. Sensitivity is rated at 105 decibels with a matching signal-to-noise ratio of 105 decibels.

Bluetooth 5.4 connectivity and battery

Wireless connection relies on Bluetooth 5.4 for stable pairing with compatible devices. Each earbud provides up to 8 hours of operating time on a single charge. The charging case extends total playtime to 48 hours. Replenishing the case takes 1.5 hours. There is no 3.5 millimetre jack connector on the unit.

Sustained use comfort and call clarity

At 0.8 ounces the earbuds remain light enough for extended sessions without pressure buildup. The memory-steel clip flexes to individual ear shapes for a secure fit during movement. Deep Neural Network noise cancellation isolates the speaker’s voice from background sound during calls. Dual modes let the user switch between music and low-latency game settings as needed.
