I'm so envious of Sica's vibrato - it is so beautiful!

Tiffany's smooth and soft voice with Jessica's powerful and neat voice :-)

jessica did a really beautiful job in this performance. her voice is soothing.

I really like both of their voices, but my heart will always be for Tiffany. Whenever i hear Tiffany's voice i just feel really comfortable. I know that Jessica has more control over her voice and it's pretty clear but i become so happy when i hear Tiffany's voice. Her voice just makes my day and i dont care what anti's have to say about her, not just her voice but her in general, the way i feel about her it is impossible for me to describe how much i love her in words. Tiffany i love you ^_^

I wish they sang together more often cus their voices really do compliment each other. And the cutest part, which wasn't shown, was when afterwards, Jessica said she was shivering from the top of her head to her feet after singing with Fany and didn't know why. And she made Yuri hold her hand and Seohyun hug her to stop shivering. And Fany was like, "I think she likes me!" XD

jessica's voice is flawless! and tiffany's voice is so husky and sweet!

Wow Tiffany and Jessica did a great job of covering an RnB song! Their voices compliment each other very well. I can listen to this all day.

Here in 2019. I miss my JETI couple so much!

JETI deserves more duets

jessica's voice is so sweet.. melting my heart.. flighting jessica!! flighting SNSD

if JeTi sings this duet in 2015 even though Jess is out of GG, that would totally SLAY! JeTi

Tiffany's voice is so sweet!

2016 already but still watching this.. i miss them so much and jessica's voice how i wish for them to have interaction in the future ,this song really is for them

I am so fall in love with Jessica's heavenly voice ~ it so sweet and heartwarming! It made me feel peaceful to listen to this song, especially with Sica sing it!

I've always loved Tiffany's voice... She sings in the most natural way, not even a bit strained. I love this song too ^^.

i love jeti after taesic, i think only jessica vocal can match to other member regardless member like taeyeon, tiffany or seobaby.. her vocal really really unique..

몇년째 듣는지 잘불렀다 진짜

@ 2:33 that run that Jessica did.. it's really quick but it really does show how PRO she is at controlling her voice!!!

달달하다 제시카 목소리...

Even after all these years, I will consider this one of the best duets I have ever heard. When you listen to this, you can truly feel the emotion and passion they exude through their singing. That is what makes this a great cover. It was magical listening to this long again, and still the same today.

I love Jessica's sweet voice and Fany's husky voice. They really compliment each other 3

I really love it when these two sings together! Their voices complemented each other! They're the perfect combination!! JeTi!

jessica daebak :p

내가 이 노래에 입문한게 이 둘 때문인데 죄다 영어댓이넹

I wish they did more duets! their voice goes really well together... this and genie in the bottle are my fav songs they covered

Missing them a little bit too much these days 😢

of course jessica's voice is the sweetest melody i've heard ! she melts my heart away . i love sicca ! :)

하느니무감사합니다 이거 진짜 레어인데 황묭 사링해....ㅜㅜ

i'm falling in love w the melody , their voices are just so beautiful, give off an angelic feeling JeTi has so much chemistry when they sing duet with each other JeTi jjang

My favorite singer from GG is Taeyeon, second would have to be Jessica, her voice is so sweet yet she always sing so easily and wonderfully

Jessica's voice is great!! Tiffany's voice is great!! All is Great!! SNSD Jjang!!

The best duet in soshi for me because their voices are so different yet complements each other. I was so excited when i heard of their caramel coffee duet & was hoping for their subunit 😭

This is my favorite song.Jessica is the prettiest singer when she sings.

They sang it so beautifully. You love Jessica!! ❤

I really like Jessica's voice!!!:) i used to think how come she always sing the softest during live... but then i realised her voice is really fragile so if she dance and sings... it wont sound really strong or loud... but from this video..I can totally tell that she has an AMAZING VOCAL!!!! and she sounds much better when she isnt dancing:)

아직까지 들음 크

Maybe it's only me but it's hard to find a bubblegum pop girl group who can actually sing and has super beautiful voices and SNSD has everything. Dance, vocal and models. They are like the whole package. You want singer? There's Jess, Tiff, TY, Seo Hyun, Sunny. Actress? Yuri, Yoona, SY (maybe hehe). DAncers? Hyo Yeon, Yuri, Yoona, Jess, TY. DJ? Sunny, Soo Young.. See, you get whatever you want in this group! They just changed my opinion in cute singing girl group.

March 2016 still watching this video. Because jessica's voice.

This is why these two are my favorite when it comes to duet. Second from Taeyeon and Jessica.

It's already 2020 but I still come back to watch thissss 😍💛

Jeti harmony😢😢😢

miss sica, my bias

아 제시카 보고 싶다 ㅠㅠ

it's one of those days where i miss jeti again

honestly . The only medicine I need in the world is Fany, Jessica, or Taeyeon's voice

i can listen to this all day

Now 2016, i still watching this. So sad when i'm watching this video.. Because their voices are really matchig together, but now they're become a rival :") i wanna cry 😂😂😂

2017 and here i am still watching JeTi duets

Tiffany is perfect!!! 💓

I love how Sica's mic is right next to her mouth and Fany's is far away xD

their voices compliment each other really well and tiffany's sounds specially beautiful here

Jessica, Tiffany - Only One For You Vocal Range G3 ~ B4 ~ D5 Supported Range G3 ~ B4

Both of them are really good but when Tiffany has control of her voice... goosebumps all over.

I'm liking Tiffany's voice more and more, she really is *talented* :)

really love this duet also their Garden in the air duet is amazing.Keep shining to the both of you

I miss this song. ㅠㅠ I miss JeTi so much!

Both of their voices compliment each others'. Jessica's voice emphasizes how delicate and smooth Tiffany's voice. And when we hear Tiffany's voice, it lets us realize how husky yet gentle Jessica's voice is.

Who listen to this in 2019?! ❤️✌🏻️

i always play this song on my ipod coz it makes my day beautiful,xD

Love this duet of JETI,😄

2020 ก็ยังฟังอยู่ ฟังแล้วยิ่งคิดถึง;) Waiting for you always OT9

*TIFFANY UNIQUE & ANGELIC VOICE, ITS PERFECTION!*

Jessica Voice +Tiffany Voice= A wonderful peace of music that's unbreakable

Jessica and Tiffany are definitely good with each other. Their voice's synergise and compliment each other. I really like their songs.
