The Cooler Master CH351 uses an over-ear fit and tips the scale at 328 g, making it a moderately sized closed-back headset. It comes with a detachable cable, which adds a degree of convenience when switching between wired and wireless use or replacing a worn cable. Stereo speakers are included, while the headset does not support RGB lighting, cannot be folded for compact storage, and the cable itself is not tangle-free.
The CH351 is equipped with two 50 mm neodymium drivers covering a full 20 Hz to 20,000 Hz frequency range, with an impedance of 32 Ohms and a sound pressure level of 100 dB/mW. It includes both active noise cancellation (ANC) and passive noise reduction, helping to limit unwanted ambient sound from either direction. The headset also supports virtual surround sound and spatial audio, rounding out a sound profile designed for immersive gaming and media use.
The CH351 features a single removable noise-canceling microphone with a frequency response spanning 100 Hz to 8,000 Hz and a sensitivity of -40dBV/Pa. Its detachable design means it can be taken off entirely when not needed, and a built-in mute function provides quick control over audio input during use.
The CH351 runs on a built-in rechargeable battery rated for 30 hours of use, and a battery level indicator lets users keep track of remaining charge at a glance. The battery is not removable, so recharging in place is the only option when it runs low.
The CH351 supports four connection methods — 3.5mm, USB, 2.4GHz wireless, and Bluetooth 5.4 — and is compatible with PlayStation, Xbox, PC, and Nintendo Switch. Wireless Bluetooth reach extends up to 20 m, and the headset charges and connects via USB Type-C. NFC pairing is not supported, so Bluetooth devices need to be paired through the standard process.
The CH351 includes an on-device control panel for quick adjustments and supports multipoint connectivity across up to three devices simultaneously, making it easy to stay connected to multiple sources at once. It can be used as a headset for voice calls and communication, though it lacks an in-line control panel and has no vibration function. A travel bag is not included in the package, and the headset comes with a 2-year warranty.
