Brown Eyes (브라운 아이즈) was a Korean musical duo, specializing in ballads. Although both members have powerful voices, they were initially disregarded because of their physical looks. However, their albums had extremely high sales, each surpassing the 600 000 mark. The group split up, though, after rumors of internal fighting. Naeul has gone to lead the group Browneyed Soul, while Yoon Gun has released three solo albums.
