Move between low-latency 2.4 GHz wireless, Bluetooth 5.4, and wired USB Type-C audio without changing headsets. Cooler Master CH-351-MC, sold as the CH351 Macaron, combines 50 mm drivers with built-in 3D surround sound for game audio, voice chat, films, and general desktop listening. One headset can serve systems using USB Type-C audio and devices connected through Bluetooth or the 2.4 GHz wireless link. Bluetooth pairing supports up to three devices, with a button control for switching among paired connections. The 2.4 GHz wireless connection supports transmission distances up to 20 m, while the internal battery provides up to 30 hours of wireless operation. Built-in sidetone provides real-time voice monitoring, allowing users to hear their own microphone level during team communication and disable the function when it is not needed. An adjustable boom microphone uses a unidirectional pickup pattern for focused voice capture and noise isolation. The Y-frame construction is shaped for a secure fit, reduced sound leakage, and passive noise isolation around the ears. The boom microphone, cable, and ear pads are removable, allowing damaged or worn components to be changed without replacing the complete headset. This combination of three connection methods, multi-device Bluetooth pairing, removable parts, and sidetone monitoring distinguishes the Macaron configuration for users who move between gaming and general audio devices.
