honestly for any concert please wear earbuds. i see so many people going to concerts without them but please protect your ears. if you buy some nice reusable ones the music will still sound good and also believe me you don’t want to have a constant ringing in your ears
I would recommend reading the venue's FAQ, so you understand what you can & can't bring to the concert. As every venue has different requirements like bag dimensions (aka how big/small of a bag you can bring).
depending on how old you are and how tall you are, this can go both ways. Katseye can be full of little kids (speaking as someone who went in 2025) and moms that would do ANYTHING for their kid. they will be willing to push, lie, and get you kicked out of the concert, if it means their kids will get to see their faves. that's why you gotta FIGHT for ur spot. (i had a very bad experience with KATSEYE last year) Stay calm, and make sure everything is prepared!
Definitely go look for some videos on "what to bring to a kpop concert" on YouTube or tiktok! Also not all videos mention these but bring a flashlight if it gets dark and you don't have a light stick, and bring maybe earbuds since it can get loud!
