It has many features: - A control button to quickly turn the microphone on and off. - A volume control button. - A light in the color shown in the pictures when connected via USB cable. - You can adjust the size significantly, making it larger or smaller depending on your preference. - The sponge is comfortable, soft, and not hard, and the material covering it is of excellent quality and practical if you take care of it. - Finally, and most importantly, its noise isolation is excellent because the sponge surrounds your ear and blocks outside sounds—can't get clearer than that. - The microphone sound is extremely clear, meaning the headset is great for gamers, immersing you in another world. As for why I'm selling it, I don't use it much since I rarely play games. I originally bought it for noise isolation and the microphone, but I no longer need them.
