I purchased the Astell & Kern AK120.
I've several IEMs, old and new (E3c Shure, Etymotic ER-6i, Ultimate Ears Super.Fi 5 Pro, Philips Fidelio S2) and I also have the Grado SR80 and AKG K701.
But I would like a new IEM that I can do to better appreciate the quality of the player.
I am particularly interested in the definition of the sound and the spatiality of the scene.
What do you recommend with a price within $ 500?
Thank you for your help.
