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

One 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

The most refined S12 to date. Smoothest treble out of all the S12, and very little Planar timbre while keeping up the great tech and detail. Jays Audio Youtube Channel

Planar with the most "wow" factor. Spacious heead stage Treble can be too much Tim Tuned Youtube Channel

Reviewer Score
Very energetic. Very detailed. Very bright. Noticeable recession in mids - it is V-shaped after all. Planar timbre is quite noticeable and can sometimes make this sound unnatural. Previously Owned

I think the s12 is fine, the pro and z12 don't add too much value Jaytiss Youtube Channel
