The KZ Carol has passed authoritative safety checks and obtained utility model patent certification in multiple countries, ensuring reliable quality. Additionally, it meets the IPX5 waterproof rating, making it suitable for a variety of environments, whether outdoors or indoors.
Super-Linear Wideband Driver for Professional Sound
KZ has developed and mass-produced a new generation of super-linear wide-band internal magnetic dynamic drivers. This self-developed driver features an N52 neodymium-iron-boron magnetic system and a high-tension voice coil. Whether delivering deep bass, precise midrange, or detailed high frequencies, this technology provides an outstanding and immersive listening experienc
High-Performance DSP for Superior Sound Quality
KZ's acoustics team has combined over a decade of HiFi tuning experience with a new high-quality DSP audio module, resulting in a remarkable enhancement in sound performance. After extensive fine-tuning, the KZ Carol achieves excellent tonal balance, dynamic range, and bass depth, delivering a refined and immersive listening experience.
Enhanced Deep Bass and High-Precision PCBA Technology
By precisely controlling low-frequency dynamics, this technology delivers a powerful, deep bass experience with enhanced clarity, free from muddiness. The high-precision 6-layer PCBA offers significant advantages over traditional 4-layer boards, including improved resistance to circuit interference, better heat dissipation, and enhanced electromagnetic compatibility. This advanced design ensures superior performance, reliability, and rock-solid quality.
6-Microphone Hybrid Noise-Canceling Technology
The 6-microphone hybrid noise-canceling system includes one feedforward, one feedback, and one dedicated call microphone on each side, with each microphone optimized for different frequency ranges. Unlike systems with 2 or 4 microphones, which often compromise noise cancellation or share microphones, this design ensures superior noise-canceling depth and clarity.
Dual Transmission FPS Ceramic Antenna with Bluetooth 5.4
The KZ Carol features a dual transmission FPS ceramic antenna, offering exceptional stability and strong anti-interference capabilities. Paired with Bluetooth 5.4 technology, it ensures smooth, uninterrupted communication with faster transmission speeds, lower power consumption, and enhanced interference resistance, delivering a highly stable connection even in complex environments.
Four Modes
- High-Performance Mode: Tap the left or right earbud three times to activate "High-Performance Mode," reducing latency to approximately 55 ms. This ensures seamless audio-video synchronization and precise sound localization for an immersive gaming experience.
- Transparency Mode: Press and hold the left earbud's touch control for 2 seconds to allow external sounds to be heard clearly, making conversations effortless without removing the earbuds.
- Active Noise-Canceling Mode: Press and hold the left earbud for 2 seconds again to reduce environmental noise, providing an immersive listening experience, even outdoors.
- Standard Mode: This mode offers balanced output across all frequency ranges, making it ideal for a wide variety of music genres.
AI Noise-Canceling Technology for Clear Calls
KZ Carol breaks industry limits with its 6 high-performance microphones and advanced AI neural algorithms. The acoustic chamber, designed using the Helmholtz resonance principle, effectively targets external noise and wind interference, ensuring a clean and clear voice call experience.
Battery Safety and Extended Life
The KZ Carol features a high-purity lithium cobalt oxide battery, offering high energy density, long-lasting power, and stability. With a built-in MOSFET protection IC to prevent overcharging, over-discharging, and overcurrent, it ensures safety and durability. The environmentally friendly design aligns with KZ's commitment to sustainability. The single battery life lasts approximately 7 hours, while the charging case extends the total battery life to 42 hours. Additionally, just 10 minutes of charging provides 2 hours of listening.
Tech-Themed Aesthetic with Custom Breathing Light
KZ Carol combines a transparent, tech-inspired design with its exclusive custom breathing light, powered by advanced pulse-width modulation (PWM) for enhanced performance. The visible internal components showcase meticulous craftsmanship, while intelligent algorithms monitor battery levels and modes for precise control. Even after tens of thousands of cycles, the breathing light remains as bright as ever. KZ Carol also offers three sizes of skin-friendly ear tips, ensuring a perfect fit and exceptional comfort, whether for daily commutes or intense workouts.’
Smart Dual-Connect for Seamless Device Switching
KZ Carol can connect to two devices simultaneously, whether on Android, iOS, or Windows systems. For instance, if you're watching a show on your tablet and receive a call on your phone, KZ Carol allows you to effortlessly answer the call through the earbuds, eliminating the need to manually switch between devices.
