Thanks
@Dobrescu George for your take on the ZSN.
May I know what eartips did you use to listen for your impressions?
Our daughter listens to metal. I must say i cannot anymore keep up with such overload of sonic stimuli coming direct to my eardrums a few millimeters away.
These are my own impressions with regard to perception of bass resolution (textures, speed, decay, etc.):
I find natural acoustic instruments more suited to the task. The double bass, the violoncello, the lowest octave of the piano, the harp, the bass trombone, the tuba, contrabassoon, the pipe organ. Even the human voice. Listening to these in solo, in chamber music and in concert is for me the essence of the sound such instrument produces, in relation to its interplay with others as a whole, and the sense-impressions and emotions and mindset all of it evoke. Music.
When I listen to, say, Beethoven's Third or Vivaldi's Four Seasons or a Bach Cello Suite or Charlie Mingus from a decent stereo system, once I perceive that it resolves and reproduces with a certain threshold of fidelity the music that's familiar to me I get engaged and involved and am gone.
Now we have transducers that can fit over or even inside our ears, but the same principle applies.
The instruments i've mentioned—save for the human voice—can and do go down to the lowest audible range, sub-bass. The pipe organ can go even lower. With these instruments one can, through decent headphones, perceive how bass notes are resolved, individually or in complex series of tones, fast or slow, and how the resulting combinations lead to textures that, by a certain recording or performance by a certain artist or artists, arouse our thoughts and feelings.
With the KZ ZSN, I find the music I am
most familiar with, be it simple, intimate, aggressive, complex or wildly exuberant, are sufficiently reproduced and resolved, notably in the lower audible range. No congestion. No bloat.
On the other hand, in late-night listening, I find that the Simgot EN700 Pro can resolve even better. But then what I listen to is music and if the speakers or headphones are good enough I get lost in it in an instant.
You say the ZSN is good. Given your context, that may be construed to be so-so, humdrum, mediocre.
I say the ZSN is very good. And given my context: price (bought it for less than $11); build and design; aesthetics; its cable—all of which translate to value; and the music I listen to; that may even be construed to be exceptional.
Long story short: we have a difference of opinion. And I'm merely a housewife approaching senior citizenship who can't hear a thing beyond 14,800 KHz.
But what does it matter? This is, after all, an impressions thread and I do appreciate and respect your thoughts and your right to express them. And I think you've made some good points, too.
