The P1 MAX from TinHifi is another example of a budget friendly earphone with a planar magnetic driver that has an admittedly great audio performance for the price. The lower treble range of the original S12 sounds a tad more brightness and dynamism, compared to the S12 Pro version, which is a bit softer and forgiving in this area. Both are pretty equal in terms of upper treble extension and resolution, while the S12 Pro has the slightly edge in terms of authority when I listen to soprano voices or to instruments such like ride or crash cymbals. There is plenty of energy here and a touch of brilliance but only as much as is needed for giving a shining and luminous character to the sound never crossing the point to harshness and stridency. The rounded shape perfectly filled my ears, and when paired with the right tips, the S12 Pro gave me a very nice experience. To be fair, they aren’t as cozy as a semi-custom fit could be, but I’d still rate them a solid 8 out of 10 in this aspect and I’d place them above all the other models I’ve reviewed this year Isolation

The elegant kidney shaped earpieces are made of aluminium alloy, painted in blue as opposed to the grey of the original S12. As with the original S12, there is a chrome accented on the square protrusion on the face of the IEMs, rather like a top quality car with chrome trims.

The same goes for the IMR EDP and EDP Ace, again like the I3s, the EDPs have been overshadowed by the S12 Pros for me. The EDP Ace however, comes fairly close with its DD bass and the note decay probably aided by piezo, the Planar Magnetic driver, if not the design of the chamber.

The soundstage is wide and spacious with good positioning accuracy but it is mostly expanded in the horizontal axis without any significant depth layering and holographic relief. Inside of the S12 is LETSHOUER’s first-ever custom pair of 14.8mm planar drivers capable of pushing a respectable frequency range of 20Hz up to 20kHz.

The S12 PRO is resolving, crystal clear and transparent in the mid-range with a natural voicing that is combined with the already excellent bass performance to make for an immersive and realistic listening experience perfectly suitable for classical music and not only.
