he Bloody G521 Gaming Headset is a wired USB headset built around virtual 7.1 surround sound, 50mm neodymium speaker units and an omni-directional noise-canceling microphone. Its suspended auto-adjusting headband, large protein-leather ear pads and 7-color breathing illumination make it a practical choice for PC gamers who want positional gaming audio, voice chat and a comfortable over-ear-style fit in one setup.

Virtual 7.1 Audio for Gaming

The Bloody G521 Virtual 7.1 Gaming Headset is designed for gamers who want more spatial information than a basic stereo gaming headset. Bloody's virtual 7.1 system is intended to create a wider directional sound field, helping make the position of footsteps, movement and other in-game audio cues easier to distinguish in compatible games and software.

For PC users, the G521 works with Bloody's CM7.1 software, which provides Smart 360 Gaming, 2.0 Audio-Enhanced Multimedia and 7.1 Surround Sound modes. This lets the headset serve both gaming and everyday multimedia use without relying on wireless connectivity or batteries.

50mm Neodymium Speaker Units

Inside each earcup is a 50mm speaker unit with a neodymium magnet. Bloody specifies a headset frequency response of 20Hz–20kHz, 105dB sensitivity and 16-ohm impedance.

Omni-Directional Noise-Canceling Microphone

For multiplayer gaming and voice communication, the G521 includes an omni-directional noise-canceling microphone. Bloody rates the microphone at 100Hz–10kHz frequency response with -45dB sensitivity.

The noise-canceling specification applies to the microphone, helping reduce unwanted surrounding sound from reaching teammates during voice chat.

Suspended Headband & Comfortable Ear Pads

Comfort is handled by an auto-adjusting suspended headband with a soft leather support section. Instead of requiring repeated manual adjustment, the suspended design is intended to adapt naturally to different head shapes.

The headset also uses large protein-leather ear pads, providing a cushioned contact area around the ears for gaming, Discord calls and longer PC sessions.

7-Color Gaming Illumination

The earcups feature a 7-color circular breathing light that adds illumination to a gaming setup while the headset is connected. Bloody specifically describes this as a seven-color breathing-light system.

This makes the G521 suitable for users who want some lighting in their gaming headset without making lighting the main reason for choosing it.

Wired USB Connectivity

The Bloody G521 uses a wired USB connection with a 2-metre cable. There is no wireless mode or battery to charge, making it suited to a fixed PC or laptop gaming setup where consistent wired connectivity is preferred.

Bloody CM7.1 Software

The G521 is supported by Bloody's CM7.1 software. Bloody provides dedicated Windows 10 and Windows 11 downloads from the G521 product page, while its CM7.1 software documentation lists support for Windows 7, Windows 8, Windows 8.1, Windows 10 and Windows 11.
