Comparison:
MrSpeakers Aeon:
With the foam being inserted, the bass extends deep, decays a bit faster yet for the most part, slams quite polite. During some of the tracks in Nina Simone's album the drum sounds clean and controlled, but it never would give me a sense of rumble. Notice that despite the bass being controlled, it does not give you a presence of the natural thumping sound of real-life music. In comparison the Elear is way more dynamic on the lower end.
The mids is flat with almost no depth. Elton John's deep, magnetic voice does not sound rich at all - although it has great, great layering that draws the instruments from beneath. I would call it borderline neutral.
The highs is pleasant to hear but not something to remember. Less refined, less detailed, less fatiguing than HD800/ Utopia, but more boring and analog-like. Nina Simone at her finest sounds as if she were singing to a tree. No sibilant noises can be detected, yet it does not give any treble sparkles either.
Soundstage wise Aeon is nothing but mediocre: the sound is compressed in a dense&small studio-like space. Could be said as wide but definitely not tall. Clarity and transparency is just average - it does not sound muffled at least, but does not offer the razor-sharp details either. I just can't hear the mumbling sound of Glenn Gould singing to himself while playing Bach's fugue very clearly. Plus the sound on its own does not sound natural, with more of a digital touch to it. The confused positioning of instruments in large orchestral works shows the technical [in]capabilities of the driver.
So overall no glaring flaws; very neutral, a decent all-rounder with very middling toning. Comfort wise... the leather pads feel nice to touch & smell, but the [slightly loose] clamping force as well as the earcup designs often forces me take it off, re-configure the wearing and put it back on a number of times during listening sessions.
ZMF Eikon:
Very good bass. Extends deep, decays fast, drums have a gripping sense of power in them yet not losing any control or cleanliness. Absolute no complaints - I have to say I'm a secret basshead after enjoying the Eikon.
The mids is the central pillar of these cans. Lush, rich, full-bodied, natural, textured...you name it. Listening to male vocals is a dream full of awesomeness - but there are times when the entire staging of the music is overshadowed by the mids that you lose track of the other parts that are supposed to be there. Also it is a bit too warm to be approaching neutrality.
The highs loses some details while adding up a bit darkness & dirt to the tremble. Very smooth, very refined, quite soft with no sibilance... Female vocals (i.e Betty LaVette) can sound very natural, very life-like with the just right dose of realism and musicality. In terms of detail retrievals... it is being edged out by either HD 800 or Utopia in a huge margin.
Overall I expect the separation, transparency and clarity to be better: it has a very resolving (and forgiving!) very full-bodied, honey-like sound of liquid...though for orchestral pieces the sounds tends to blend with each other. The soundstage is quite decent for a closed-back and rivals open-backs such as Elear & HD600 - Eikon has an intimate presentation from every region and does not tend to sound compressed if not listening to large orchestral pieces.
Sony Z1r:
Several major points:
A dark signature that sounds muffled at times; bass is way too much and bleeds into the mids; the highs has so many "zing" "zing" "zing" noises for me to bear; comfort and build quality is top-notch. Quite disappointed.
Will add more details to Z1r and Eikon later.
