QCY Crossky C50i Earbuds (Gray)

The gray QCY Crossky C50i are wireless open-ear earbuds equipped with 12-millimeter composite drivers, LDAC codec support, and Hi-Res Audio Wireless certification. The model uses Bluetooth 6.0, a 4-microphone system—2 in each earbud—dual-device pairing, a 45-ms low-latency mode, and IPX5-rated sweat and splash resistance. The earbuds offer up to 8 hours of playback on a single charge, and with the charging case, battery life can reach up to 42 hours, making them suitable for music, calls, computer work, and everyday activities.

C-Bridge design that fits comfortably in the ear

The Crossky C50i features an open-ear design with a flexible C-Bridge that wraps around the ear without needing to be inserted deep into the ear canal. Inside, an ultra-thin, 0.5-millimeter frame made of shape-memory alloy is used, and the elongated, contoured bridge helps maintain a stable and comfortable fit. This design also helps you stay aware of ambient sounds, which can be useful while walking, working, or exercising.

12-millimeter drivers and Hi-Res Audio

Sound reproduction is handled by 12-millimeter composite drivers, designed to deliver clear bass, articulate mids, and detailed highs. Support for the LDAC codec allows for audio transmission at rates of up to 990 kb/s on compatible devices, and Hi-Res Audio Wireless certification confirms support for high-quality wireless audio. As a result, these earbuds are ideal not only for podcasts and calls but also for listening to music where clear detail is important.

4-Microphone Call System

The QCY Crossky C50i features a 4-microphone system—two in each earbud—which supports clearer calls. The microphones are angled at approximately 30° to better align with the natural position of the earbuds on the ear and more effectively capture the user’s voice. This design makes it easier to make phone calls and engage in online conversations both at home and on the go.

Up to 42 hours of battery life and connection to two devices

On a single charge, the earbuds can last up to 8 hours, while with the charging case, the total battery life is up to 42 hours. Each earbud has a 40 mAh battery, and the case is equipped with a 500 mAh battery and a USB-C port for charging. The Dual Connection feature allows you to connect the Crossky C50i to two devices simultaneously and conveniently switch between them, for example, while using a smartphone and a laptop. The QCY Audio app lets you check the battery level, use preset equalizer settings or your own EQ, customize control functions, update the software, and locate your earbuds.

Low latency, IPX5, and physical buttons

The low-latency mode, with a latency of approximately 45 ms, helps minimize the delay between video and audio when watching videos or playing games. IPX5-rated water resistance protects against sweat and splashes, making the earbuds well-suited for workouts as well. Controls are handled via physical buttons that let you manage playback, skip tracks, answer and end calls, launch the voice assistant, and activate game mode. The gray version of the Crossky C50i features a rounded charging case with a glossy, mirror-like finish and a decorative IMF ring, which gives the entire design a distinctive look.
