TOTL mids. Most 3D and holographic staging yet. Imaging, separation, layering, and staging are all S level - only thing that's holding it back is the darker treble which can lead to softer notes vs, Diva, for example.The most immersive set for rock, alternative, ballads, and classical. An 07M that scales better with better staging. Great clarity and seperation. Treble is pushed back but still clear and evident in tracks (at higher volumes). Could use more low-end (but not an issue) and sharper note transients. Takes you on a journey. Needs to be listened to at high volume for the full effect.

Very engaging and very natural sounding. Decent technicalities. Instruments sound correct. Staging and imaging very good for an IEM. Very enjoyable. Leans dark and maybe a bit lacking in treble extension but also very easy to just enjoy the music which, at the end of the day, is what we even want from IEMs right? Previously Owned

Comment: My favourite of the EJ lineup. Vocal centric with great clarity and thick note weights in the midrange Bass may be too polite
