Hi, I listen to some kpop too. And oh, you like Yoona haha. Ok, so you want to know what slow is. Well, imagine you're playing a computer game that requires lots of graphics power and processing power. But you're laptop just can't keep up and it lags abit. That'd what slow is in audio too. The sound lags just a little and is produced so slightly slower because basically its a dynamic driver earphone. A BA earphone would some much quicker and I would say better for pop or kpop in your case. Where do you live? Oh, and I tend to find that the bass of the ie8 often drowns out the mids just a little...so a BA earphone would be best for you and your genre. Oh, and I'm glad you DIDNT go for BEATS. It's a huge waste of money. Before I forgot, welcome to head fi! Sorry bout your wallet
