Ultra-Discreet Earbuds for Sleep and Work

The CNBRO SK19 earbuds are an ultra-compact in-ear model designed to sit almost flush with the ear canal. Their low-profile shape targets side sleepers and professionals who need audio that stays hidden during calls or rest. Balanced armature drivers deliver sound across a 20 Hz to 20,000 Hz range with 10 ohm impedance.

Four-Hour Buds with Twenty-Hour Case

Each charge provides 4 hours of continuous playback from the buds themselves. The charging case holds an additional 20 hours, reaching a combined 24 hours before you need a wall outlet. Bluetooth 5.3 handles the wireless link, and the case recharges fully in about an hour. Sound isolation passively reduces background noise without active circuitry.

Tiny IPX-Rated Shells with Touch Controls

The plastic earpieces measure 3.23 cm by 1.61 cm by 4.2 cm and carry a water-resistant rating for sweat or light rain. Touch surfaces on the buds manage volume and playback directly, removing the need to reach for a phone. A built-in microphone supports calls, and the package includes a single pair of ear cushions for fit adjustment.
