QCY Crossky C30S Open Ear Earbuds Review: Comfort, LDAC Sound, and Long Battery Life















The QCY Crossky C30S open ear earbuds are designed for users who want to stay aware of their surroundings without sacrificing sound quality. Unlike traditional in-ear earbuds, the Crossky C30S use an open-ear clip-on design that sits comfortably outside the ear canal. With features like Bluetooth 6.0, LDAC Hi-Res audio, deep bass, long battery life, and an ultra-light build, these earbuds are clearly aimed at runners, gym users, and anyone who values comfort during long listening sessions.

QCY Crossky C30S Earbuds Features

Comfortable and Secure Open-Ear Clip Design

Comfort is the core strength of the QCY Crossky C30S. Each earbud weighs less than 5 grams and uses an ergonomic anti-Z-shaped ear clip that gently wraps around the ear. The nickel-titanium alloy frame automatically adapts to different ear shapes, ensuring a stable yet pressure-free fit. This design makes the earbuds ideal for workouts, running, cycling, or extended daily use without ear fatigue.

Hi-Res Audio with LDAC and 10.8mm Dual-Magnet Drivers

Despite their open-ear design, the Crossky C30S deliver impressive sound quality. They feature 10.8mm dual-magnet drivers paired with a carbon fiber diaphragm, producing deep bass, clear mids, and crisp highs. With Hi-Res Audio and LDAC certification, the earbuds support high-quality wireless audio up to 96kHz/24-bit. Dynamic audio tuning adjusts sound output up to 48,000 times per second, creating a more balanced and immersive 360-degree spatial sound experience.

Directional Audio with Minimal Sound Leakage

QCY uses Directional Audio 3.0 technology combined with reverse soundwave cancellation to reduce sound leakage by up to 99.5%. This helps keep your audio private even in public spaces. At the same time, AI-powered microphones and a wind-blocking structure ensure clear voice pickup during calls, making conversations sound natural and uninterrupted.

Bluetooth 6.0 with Dual Device Connectivity

With Bluetooth 6.0, the Crossky C30S offer a stable, fast, and power-efficient connection. Multipoint connectivity allows the earbuds to connect to two devices simultaneously, letting you switch between watching content on a TV and answering calls on your phone without manual reconnection. This feature adds real convenience for multitasking users.

40 Hours of Battery Life with Fast Charging

Battery life is well-suited for active lifestyles. The earbuds offer up to 6 hours of playback on a single charge, while the charging case extends total usage to around 40 hours. Fast charging via USB-C ensures that a quick 10-minute charge provides up to 1 hour of playback, perfect for last-minute workouts or quick commutes.

IPX5 Water Resistance for Sports and Outdoor Use

The QCY Crossky C30S come with an IPX5 rating, meaning they can easily handle sweat, rain, and everyday splashes. Their durable build makes them a reliable companion for outdoor activities and high-intensity workouts.
