The KZ AN01 Bluetooth Module is a cutting-edge wireless upgrade for audiophiles and gamers who want to liberate their wired in-ear monitors (IEMs) without sacrificing sound quality. Designed as earhook-style adapters, these modules combine Bluetooth 5.4, Active Noise Cancellation (ANC), LDAC HD audio, and ultra-low gaming latency—making them a versatile choice for music, calls, and competitive gaming.
Let’s dive into the features, performance, and ideal use cases for the KZ AN01.
Key Features of the KZ AN01 Bluetooth Module
1. Bluetooth 5.4 with LDAC & aptX Support
The KZ AN01 leverages Bluetooth 5.4 for stable, low-latency connectivity. It also supports LDAC and aptX codecs, ensuring high-resolution audio streaming (up to 990kbps) for lossless music playback. This makes it ideal for HiFi enthusiasts who demand studio-grade sound from their IEMs.
2. Active Noise Cancellation (ANC) & 4-Mic ENC
- Hybrid ANC reduces ambient noise by up to 25dB, perfect for commuting or noisy environments.
- Quad-mic ENC (Environmental Noise Cancellation) ensures crystal-clear calls by isolating voice from background chatter.
3. Ultra-Low Latency Gaming Mode (40ms)
For gamers, the AN01 offers a dedicated low-latency mode (40ms), syncing audio seamlessly with on-screen action—critical for FPS, MOBA, and rhythm games.
4. 40-Hour Playback & Fast Charging
- 6-hour battery life per charge (earhooks alone).
- The charging case extends usage to 40+ hours, with USB-C fast charging.
5. Universal Compatibility with KZ/CCA IEMs
The AN01’s 2-pin (0.75mm) connectors work with popular KZ and CCA models like:
- KZ ZS10 Pro, ZSN Pro X, DQS, ZAR
- CCA CRA, C12, C10 Pro
Simply detach your IEM’s wired cable and snap on the AN01 for instant wireless freedom.
Performance & Sound Quality
Audio Fidelity
- The LDAC codec delivers near-lossless audio, preserving details in highs and mids.
- Bass response remains tight and punchy, thanks to the dedicated DAC amplification.
ANC Effectiveness
While not as powerful as premium over-ear ANC headphones, the AN01’s hybrid ANC effectively cancels low-frequency hums (e.g., airplane engines, AC noise).
Gaming & Latency
In gaming mode, latency drops to 40ms, eliminating noticeable audio lag—comparable to wired setups. Ideal for mobile gaming (CoD Mobile, PUBG).
