love the way she put off her earphone

among all female main vocal idols... taeyeon is the only one that doesn't make me feel annoyed when she hit the high note... some idols just hit the high note forcefully and is a noise to ppl's ear,,

taeyeon really don't know how to lip sync 😂 its so different when she sings live my ghad. chills.

We will know if they lip sync or not. If they not lip sync 1) she expression look very natural, the way she make the emotional singing. 2) she will make a distance between her mic and her mouth just to make sure the sound will not crack. 3) she will make a 'hard face' sometimes. And we know at the first vid she lip sync. But sometimes, i cant notice she lip sync because she was just too awesome for me. My byuntaeng jjang!

Haha, Taeyeon. She can't lipsync😂

her high notes !! perfect!! i love it so much

All her songs and ost's are on my phone its always make me put to sleep when im having a trouble time at sleeping . Her voice really make me feel so relax.

even if people hate on taeyeon, they can never deny that she has talent..

Still watching at 2015.... Falling in love again. ... And again.... And again...

Just watching this my throat is hurting by the end XD

i really like baby steps high note the best :D

and they compared it with twice?

to all haters kiss this .,!,. taeyeon #1 in Snsd vocal.. maybe jessica can hit high,but not as strong and powerfull as taeyeon.. come to thnk of it guys.

Taeyeon you're the best

1:40 this one is definitely her best. she sounds amazing!!

Taeyeon great voice. the voice take care keep...

i love the way taeyeon unpluged her headset*idk*

love how when taeyeon lypsing, she make that face on purpose

she always leave me with my mouth open!! >0

That 4th clip 😍😍

First video and second video was lipsync. Other? LIVE! AMAZING

Oh God. I love her with all my soul, she's an amazing singer, but I can't help to be worried about her voice, It's like she's forcing herself too much and It's hurting her. Anyways, for me, she'll always be one of the most beautiful voices of korea. Fighting! :)

my heart is bleeding... not by her voice.her emotion just worried about her... if she doesn't take care of herself...

TAEYEON IS THE BEST!!!! I LOVE TAENGOO!!!!!

i love you taeyeonnnnnnnn T___________________T

Taeyeon DAEBAK! ♥

I feel like those high notes are a bit out of her range, she seems to be doing a lot of effort to reach them. Hope she is not overworking her voice :/ She still sounds and looks amazing as always ^_^

i love you so much

The first two was lipsync, the rest was live

Amazing voice

Wow!!!! Love Tae so much:)

Her voice... *o*

*Goosebumb*

其實有時候要看有沒有對嘴，看泰妍唱歌的樣子就知道了，尤其是唱高音的時候，看慣她真唱的樣子了就很容易看得出哈哈泰妍在這首歌的高音真唱起來完全就是cd版本，贊

woahhhh!!!!! i love it!

you are the BEST 탱구 ㅠㅠㅠ

lol even if it were true that jessica or others do sing the high notes better, the timbre of taeyeon's voice just sounds better. Jessica's voice imo sounds shrill and sharp and not pleasing to hear =X And taeyeon taking off her headset/earpiece is always a pro move cuz she doesn't need to hear herself to know how she's singing

QUEEN

perfect

good voice! I love KIM TAENGOO

진짜 어떻게 저런 목소리가 나올수있지..

Trong số tất cả các giọng ca nữ của K-POP thì e thấy giọng Tae là hay nhất, khi nghe thấy rất thoải mái và ấm áp :X I Love Kim TaeYeon

WOW

wow..

Taeyeon is better at holding notes and really belting them out there while Jessica is more of just a high pitched note, she can go higher up than Taeyeon but she doesn't have enough to hold them for a long time like Taeyeon. I love their voices! ;D

👑

สุดยอด เลย ลูกเพ่ (o^_^o) taeyeon สุดทีรักของ ลุลู่ บ้านร่องค้า

People think differently , but I think that's why she's putting lots of effort here because of us . I know people think that Jessica can do better , but this is a video about Taeyeon . Please don't blame me if I think this . TTS fighting SNSD fighting

Yoona. Aji

0:04 you should focus on the dancers.

Well first and second video are lip sync but she's amazing yes

Taeyeon can’t lip sync lmao

Yoona. Nabila

because she shouted into his own ear =))))))))))

อัน1กะ2ลิปซิงค์ นอกนั้นสดค่ะ ^^

im weird i just pause the video to see how long the distance between her mic and her mouth.... and people keep saying she lacking of power in her voice... im rolling my eyes

1:14 why does she take it out ._.

If Jessica did this note it would be really high pitched. I think SNSD has the best vocals in Kpop.

첫번채는 립싱크네

Taeyeon is really good at singing but honestly Jesiica is better at high notes :D
