Google "新版 IE800"就有一堆文章 不相信阿陸仔也可以用英文搜尋 headmania 裡面也有給出新舊版頻響測試連結: I have noticed that the 2013 version is different from 2012 version. It looks like the sound is quite different between the 2 models and I don’t quite appreciate how the graphs from the newer model look like. I am not sure what my review unit was, but I didn’t feel they were too bassy.
