They sounds nice, though this video made me noticed one particular habit: they rarely (or ever) drop their jaw enough when singing. If they do have a vocal coach, I hope he/she teach them about it because dropping the jaw can help enhance the vocal projection, it creates more space for notes to come through (see how Yuju always had her mouth opened quite big and her jaw dropped especially during the powerful parts? Yeah, that). They already sounds pretty nice, imagine if they have fuller projection.
especially sinb, for some reason her singing style is ineffective? idk the right word but it's like there is no emphasis. I felt this since viviz debuted i thought maybe it's because of her braces. Sinb singing style turn me off sometimes especially in red sun, her voice is nice to listen to but it's like it goes in straight line where there is no impact in her way of singing. I hope they will get a vocal coach. i feel like umji is doing good, there is a balance in her but for eunha, her lack of vocal technique is showing a lot lately since she sings the type where a good singing is necessary and she is a good singer while sinb might be technically the most among them but her way of singing or style is really making their song hard to be acknowledge as a good song.
@@jjdijio sinb's singing style has always been like this, she doesn't sing much with an open voice, sadly. see her koms performance. i always thought her voice have so much more potential if she just learned a better technique. AND it seems like the lingual braces made it worse. i heard it even affects speech and sinb mentioned she's conscious of the braces showing when she's laughing or talking.
