Model overview based on user reviews
The A4Tech Bloody G521 headphones are a great budget choice for gamers, offering excellent backlight and ingenious volume control. Users appreciate the long cable and loud sound with 7.1 support, although the bass is best at maximum volume. The headphones are comfortable with an auto-adjusting headband, but some users experience discomfort after extended use. While the microphone is good, it lacks a mute button, and the headphones do not have a removable cable or software support. Despite minor issues like rustling sounds at high volumes, which were resolved under warranty, the headphones are recommended for their price, especially if purchased with a guarantee. Overall, they are praised for their sound quality and durability over time.

I ordered it at DNS, it arrived, the packaging is good, the backlight is excellent, the volume control is something ingenious, well, the microphone is good, not to say excellent. There are no cons, especially for 2 k the backlight is excellent, the volume control is something ingenious The microphone is good, not great Rodion Mamonov: use A4Tech Bloody G521 less than month |
It's been a couple of months since I bought them, I used them every day, and they haven't changed their appearance during this time, they still look and sound just as good. They sit comfortably on the head and do not put pressure. They don't make my ears sweat. The headband adjusts automatically which is a plus. no |
