HeartField, namely the artwork from sincere heart, is currently an unfamiliar name but will be something in the HiFi industry with its exclusive aesthetics and origins. The first IEM from Heartfield is called Deer which symbolizes the eternity of love in the ancient Chinese wedding ceremony, while it also means happiness and success. In a word, Deer is one of the beloved symbols for wonderful things in China.
