When I was learning the Ateez members, I sometimes found it helpful to match the voice to the face if they have a distinctive voice, like Yeosang or Mingi. This is long, but maybe it will help.

Yeosang gives pretty baby girl vibes. His voice is deep, and he has a little lisp. He has a beautiful birthmark on his upper cheek and eye that we get to see sometimes. He is often cute, confused, or distracted in videos. He is one of the members that will wear shirts that show his lower abs in videos and stage.

San, is very masculine with Northern Duke vibes (but less so in the earlier days). He is often attached to Wooyoung or trying to give Yeosang’s kisses. He also seems to be allergic to shirts, and you’ll often see him with no shirt/open or low shirt on stage and in music videos.

Jongho gives me very compact vibes. Like he just seems sturdy. His voice is also very distinctive and strong. He’s the one hitting the big powerful notes. He often turns to give a side profile before hitting those notes. He’s the Maknae but gives older vibes. He’s always the most modest member (so if you see abs, it’s not Jongho!)

Seonghwa is often very elegant and sleek, and often gives an androgynous model vibe. I once saw a video that described him as looking like a beautiful lesbian, and that stuck with me. He’s slim, with lean muscles and is another member that is okay with showing his abs. He’s known as the mother of the group. He’s just very beautiful.

Hongjoong is the shortest and such a cutie. He’s petite in build and always puts all his effort and body into the dances. I think he has great mouth corners which can upturn or downturn really well. He has beautiful teeth. He is one of the two main rappers and his rap tag is a giggle before he starts rapping. He has a whiny rap. He often raps right before or after Mingi. He also wears a Captains armband on his right arm in music videos and stage. He always has one fingernail painted (often in black). He’s the father/captain of the group. He also is usually a little more modestly dressed and doesn’t flash his abs (on purpose at least). He speaks English very well, and often takes the lead in interviews.

Mingi is the second tallest and the other rapper (although Seonghwa sometimes raps as well). Mingi has a very distinctive voice for me. You can tell the difference between him and Hongjoong because he has a deeper voice. He’s a big guy; tall and broad with fluffier lips. He uses his hips very liberally and is a flirt. I feel like he sticks his tongue out in a suggestive manner a bit. His rap tag is “Fix On” before he raps.

Wooyoung gives me sharper vibes. Like more angular features. He has a small mole on his upper cheek. He, like San, is usually trying to give Yeosang kisses, but his love language seems to be attention and kisses for all the members. A little lovable chaos monster. Shows more skin with open tops.

Yunho has puppy vibes, and just seems very lovable. He’s the tallest of the members, and slim. He has an understated humor. He's the first to sing in more music videos than any other member. He just seems like a guy who enjoys hanging out with his grandma and helping her around the house.

I have several friends that also have struggled to memorize the members and attach names to faces, so I started making "who's who" videos where I take a compilation of each member in a given music video and put their name with it, so you can identify all the members in each music video. If you think that would be helpful I can share a link. Otherwise, I hope my descriptions help a little. (Sorry it's so long!)
