Ryeowook has the best voice in my opinion. Both Yesung and Kyuhyun has unique and beautiful voices, but I think Ryeowook is better. Even if Ryeowooks voice is not the most unique one among the members of Super Junior, he has the most control of it. He has an amazing tecnique as a singer. I've never heard a sharp note from Ryeowook, and I've never heard his voice break. And that is why I consider him the greatest singer i Super Junior.
Ich denke Kyuhyun hat die beste Stimme. Er kann hohe Töne erreichen obwohl seine Stimme eher tief ist.Sie ist Powerful aber auch sanft und passt zu jeder art von Music: Dance(Pop),Ballade und auch Rock!!
Ryeowook has the best voice. He has great technique and control, and he sounds the best live. His voice never sounds tired or off-key, and it always has a lovely and clear sound to it.
Kyuhyun and Yesung are good too . . . but Ryeowook is the best.
I think donghae, kyuhyun n yesung,,,yesung he has a sexy voice I think, and donghae he has a great voice, soft and and kyuhyun he has a loud n great voice to..^^
