CCA, short for Clear Concept Audio, is a Chinese HiFi audio brand based in Dongguan that specializes in budget-oriented in-ear monitors, upgrade cables, and wireless audio accessories. The company is closely tied to Knowledge Zenith (KZ) as a sister brand, sharing manufacturing, components, and design language while positioning its products with a flatter, more reference-leaning tuning aimed at musicians and audiophiles who prefer a monitor-style sound over KZ's typically V-shaped signature.

The lineup spans hybrid multi-driver IEMs, single dynamic driver models, and balanced-armature designs at accessible price points. Notable releases include the CCA C10 and C12 hybrid IEMs, the multi-BA C16 and CS16, the CRA and CRA+ single dynamic driver models that became widely recommended in budget audiophile circles, and higher-driver-count flagships such as the APEX series. The brand also sells 2-pin detachable silver and copper upgrade cables and entry-level true wireless and Bluetooth accessories.

CCA built its following largely through coverage on enthusiast communities like Head-Fi, Headphonesty, and Audiophile-ON, where its low-cost IEMs are frequently benchmarked against far more expensive monitors. The brand is distributed internationally through retailers including Linsoul, HiFiGo, KeepHiFi, and Concept Kart, alongside direct sales via Amazon and AliExpress.

CCA has 2 products cataloged on Equipboard, including Headphones & In-Ear Monitors.
