I love these IEMs. I usually gravitate toward more laid back and warm sound signature but I chose to go for something new and exciting with the Gaea and boy did it it deliver. It's fast, aggressive, and oh my God does it sound good. My music taste leans heavily toward music with female vocals and I think this IEM truly excels at its presentation of them. It is a little leaner than some might like and the treble reaches a peak where it is almost too much, but by riding that line, it gives one of the best treble presentations I've heard in an IEM. One caveat to this is that if you care about bass rumble, don't bother with this IEM. The bass is there and it is good, but it is very quick and aggressive. As a result, you will not get the rumbly, guttural bass some of you might be after. Look to the Sony IER Z1R for that. However, if you can look past that or just don't really care for the rumbly bass, then this IEM is truly fantastic and gets a huge recommendation from me.
As a bonus, the IEM and cable are beautiful. The IEM looks chonky, but it is very lightweight and I've found it remarkably comfortable as someone who had to sell his Monarch MK2 and Moondrop Variations due to discomfort.
