The Twilight are absolutely stellar. If it wasn't for potential fit and comfort issues due to the nozzles being on the thicker/longer side, they would be recommended without hesitation as a blind buy for anyone seeking a natural timbre, coherency, instruments and voices sounding lifelike which are naturally breathing and having what some could consider being the perfect amount of detail and texture. They're an overall smooth listen all the while retaining a good amount of detail and a particularly open soundstage.
Spectacular iem! Probably the best single dd I've heard. Not ideal for parts of my library, but so fantastic for a lot of it.
