In my opinion (even though no one asked 😂 ) Jin has some of the most stable and strong vocals. I think the phrase ‘silver vocals’ describes his voice the best, Jungkook’s are also very stable and more versatile but I think soft is when he sounds best (I’m thinking strong vs soft as opposed to strong vs weak here). Taehyungs vocals are strong and the most versatile bc he has such a wide tonal range and jimin’s vocals are by far the most unique. His voice is like silver-lined porcelain and I’ve never heard anyone with a voice like him. Jhopes vocals are gentle and easy to listen to. I think I heard somewhere that he was meant to be a vocalist before bts debuted but don’t quote me on that.
