The tuning of the Iron Triangle is a bit distorted, which is not suitable for listening to Joker Xue. Akg headphones are not that cheap. I have ie60, which is very popular, especially for male voices. That is, ie60 is a headset released on 20 12, and the headphone cable is not very good. Especially in winter, the wires will freeze hard and break easily. If you are from the south, it's no problem, ie60.
