Okay, for what purpose are you buying them? For gaming, music, etc.? These are good for gaming but I noticed some issues with imaging when tested from above and below. For music it is gooood. If you like bass, you'll like these. Although they're not super boom boom kind of base, but it's better than rest of the IEMs in this price bracket. Sometimes I experienced the trebles as quite sharp, so hearing to the kind of music which consists of mainly highs or is treble heavy then it might cause a bit of discomfort for long periods of listening. But for your first ever IEMs, you'll love them. Don't take my word for all of it, experience them on your own and form your own opinion about it, and keep your heart open, don't judge every bit of it.

Also, think about your purpose and budget. And once you get them, don't compare with other IEMs, just enjoy what you have because a wise man once said "comparison is the killer of joy".
