Cooler Master Gaming CH321, Headset, Head-band, Gaming, Black, Binaural, 2.3 m
A Durable, Reliable Daily Driver
The CH321 combines comfort and durability into a daily driver that's built for PCs and consoles alike.

A suspension headband and padded ear cups provide lightweight comfort and premium sound isolation, while hi-fi drivers offer a level-up in audio, and the PVC cable prevents bends and kinks.

Add to that some understated styling and an RGB logo, and you have a headset that looks as good as it performs.

Lasting Comfort
A flexible suspension headband and plush PU leather ear cups ensure pain-free marathon sessions with incredible sound isolation through the whole battle.

Solid Sound
An onboard sound card plus 50mm Neodymium drivers on the CH321 offers top-tier sound typically found in more premium headsets.

Crystal-clear Communication
High-quality mic amplifies your voice while reducing background noise for significantly improved clarity.

Multi-platform Compatibility
An onboard sound card plus 50mm Neodymium drivers offer top-tier sound typically found in more premium headsets.

Premium Styling Without The Premium
An understated, minimalist design combined with a classy RGB logo makes the CH321 look like a pro-grade upgrade without the pro-grade price tag.

Bluetooth Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

Ear coupling Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes. The second type is actually inserted directly into the ear canal and offers some external noise suppression.
