Battery performance is another major advantage, with up to 13 hours of single playback and 52 hours combined with the charging case. Bluetooth 6.0, Dual Connection, dual-mic call noise reduction, wireless charging, IPX5 protection, and QCY App customization further enhance everyday usability.

17×12mm Driver with Bass Enhancement
The QCY Crossky R70 incorporates a large 17×12mm acoustic driver designed to deliver powerful, detailed sound from its open-ear construction. QCY complements the driver with a dedicated Bass Enhancement Algorithm and Dynamic EQ, helping strengthen low-frequency reproduction while maintaining clarity and balance across the rest of the audio spectrum. This combination provides punchy bass, natural midrange, and detailed high frequencies, making the R70 suitable for music, movies, podcasts, workouts, and everyday entertainment without requiring an in-ear seal.
Hi-Res Wireless Audio with LDAC
For listeners who prioritize wireless audio quality, the Crossky R70 carries Hi-Res Wireless certification and supports the premium LDAC codec alongside SBC. LDAC supports high-bandwidth Bluetooth audio transmission of up to 990kbps under suitable conditions, allowing compatible devices and high-quality audio sources to retain significantly more musical information than conventional Bluetooth audio. Combined with the R70’s large driver and Dynamic EQ processing, this technology helps deliver greater detail, clarity, and dynamics while maintaining the comfort and environmental awareness of an open-ear design.
Secure 36° Open-Ear Comfort
The Crossky R70 is designed for extended wear with a carefully engineered 36° stability angle that helps keep the headphones securely positioned during everyday movement and exercise. Its ear hooks use an ultra-soft Ni-Ti memory alloy wrapped in a soft silicone finish, allowing the structure to adapt comfortably around the user’s ears. Because the R70 uses an open-ear configuration rather than sealing the ear canal, listeners can continue hearing important environmental sounds, making it particularly practical for running, commuting, workouts, work, and outdoor activities.
52-Hour Battery & Wireless Charging
Battery endurance is one of the standout strengths of the QCY Crossky R70. Each earbud contains a 60mAh battery and provides up to approximately 13 hours of single playback, while the charging case incorporates a 580mAh battery that extends total listening time to as much as 52 hours. This extended runtime makes the R70 suitable for users who prefer less frequent charging. In addition to conventional USB Type-C charging, the Crossky R70 also supports wireless charging, adding greater convenience to its everyday charging experience.
Bluetooth 6.0 & Dual-Mic Clear Calls
Modern Bluetooth 6.0 connectivity provides stable wireless performance with an operating range of up to approximately 10 meters under suitable conditions. The Crossky R70 also supports Dual Connection, allowing it to remain connected to two compatible devices and switch between them conveniently. For voice communication, a dual-microphone noise-reduction system with beamforming technology is designed to prioritize the user’s voice while reducing distracting wind and environmental noise, helping maintain clearer conversations during calls at home, work, or outdoors.
QCY App, Focus Mode & IPX5 Protection
The Crossky R70 works with the QCY App, giving users access to preset and custom EQ settings, touch-control customization, battery information, Find My Earbuds, firmware upgrades, and Focus Mode. A particularly distinctive feature is the built-in White Noise Playlist, which provides calming nature-inspired sounds for concentration, relaxation, or sleep. For active everyday use, an IPX5 water-resistance rating helps protect the headphones against sweat and rain, making the R70 a versatile option for workouts and outdoor activities.
