The QCY ANC H4 wireless headphones deliver Hi-Res certified sound with 40 mm transducers, active noise cancellation (ANC) and long battery life. They support both wireless (Bluetooth 5.1) and wired (3.5 mm) connections, offer dual-microphone calling with ENC, and can be customized via the QCY App. The foldable black design and soft protein-leather earcups provide comfortable wear for extended listening sessions.

Dual microphones with ENC improve voice clarity during calls, and the headphones support simultaneous connection to two devices.
