Product Information

As to technicalities. Staging is rather average, but tall, and reasonably deep (much deeper than in the Timeless). I find the staging adequate. Timbre is ok but benefits from a warm source such as the DragonFly Cobalt or Apogee Groove. Separation and instrument placement are ok. Resolution is absolutely superb and dwarves the Timeless’.

What I do not want is to be deprived of hearing the various instruments. Excessive mid bass, which drowns out the other parts of the frequency range, but I do want to hear sub-bass, which is occasional in music in any case. I want to hear the midrange, but not to wince when the saxophone blurts out, or a voice shout at me (no matter how good the voice is). I do not want highs which make me want to pull out the earphones from my ears, but I do want to hear the shimmering highs and sparkly notes.

The S12 Pros excel in its treble extension to my ears. The treble renders music with such openness but also very good resolution. What you get is shimmering, sparkle of minutia in your music, it just sounds great. As with the bass the treble stands out for the definition, naturalness, and decay of the notes. The S12 is a slightly warm and very enjoyable set of earphones that balances its sound signature between sounding reference and musical while retaining good levels of transparency and technicalities.

Isolation and sound leakage​

Even though the S12 Pro are not the most comfortable pair, I actually had more fit issues with the Timeless. Considering that the Timeless are also more expensive, I would choose the S12 Pro between the two. Vs Tangzu Audio Zetian Wu 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.
