Questions about Senhai, Iron Triangle and AKG Headphones

Iron Triangle is suitable for this song in Asia. ES55 is fully realized in the middle and high notes, and the sound field is wide. It is the consistent style of the Iron Triangle, and the bass of the ES55 is also good. It can come out, no, it's stuffy and bloated. If you want clear music, you can consider medium and high frequency headphones. ES55 is discontinued now, which may be more expensive, close to 700. Not bad, really good, FC707400. It is also an old iron, and it is also relatively balanced. Nice shape, too. Senhai emphasizes low audio and is suitable for European and American music. On the internet, I saw that Senhai's HD series will make a few noises when playing high notes. Senhai is really good at bass and is a world-class earphone manufacturer, but I don't like low audio in Europe and America very much, otherwise I will definitely love it.
