Kiwi Ears Aether Reviews
Not for bassheads, but one of the best planars I've ever heard. Jaytiss Youtube Channel
Clean, balanced, with slight air boost in the treble. Bass sounds like a DD with great texture. Cheaper better tuned P5+2. Not as smooth as Timeless 2 with more dynamic contrast with a slight sizzle from the treble boost. Good value for a planar. Jays Audio Youtube Channel

2025-07-25One of the best planar IEMs out there. The treble is smoother and easier on the ears than most planars. Balanced sound with clean bass, smooth mids, and detailed treble. Great clarity, wide soundstage, and natural timbre for a planar. Bass might be a bit light, and treble can be a little forward for some.Gizaudio Axel original ranking

A little bit spicy in the treble (like the other planars). Relaxed upper mid-range. Warmer tuning than S12. It's a decent IEMSuper* Review original ranking
