The Crescent are excellent. At the time, I found them sonically more appealing than the KPE. And when it came to the choice which of the two to pass on to the next reviewer, I opted for the KPE...good decision as the newer Starfield are the KPE with a dialled-now low end.All of this Moondrop talk made me reminiscent of the Crescent; I threw them in the drawer of regret, after only a couple of days. I didn’t find the playback to be good enough, to overcome the annoying, cable harmonics.
At the time, I was new to IEMs and was only connecting directly to my Note 4. In your review (of the Crescents) I noted, “hard to drive”; I’ll have to give them another shot, on my Qudelix-5k.
The Crescent may not hold up quite to today's standards by their relatively slower driver, but they have a great timbre and a tall soundstage...rare in budget models at the time...2 years ago...
But what makes the Crescent truly excellent is their timbre and their haptic...great metal shells.
To me, the Crescent have always been a premium model with a sloppy resolution.
