The general sq of this IEM is soundstage oriented : the main wow effect is here. Better than on RDB (wider and deeper with more 3D aspect) it is a little bit impressive but not as coherent as I was expecting. In comparison the 334 are a bit opener and the S-EM6 more coherent, global sounding. To be more clear and extrem as the same time the lack of coherency is heard as I could distinguish 2 ways, one done by twfk the other by the DD. The same observation can be made with the RDB but even more because of the texture in the high in opposition with the low : one is thin, the other is thicker. Not very coherent.
It is accurate, not too much, just good to isolate some instruments and to hear the beat.
I though the 1+2 was very speed and impactful, it's not false but it's not as good as I could imagine : the Merlin have more impact, clearly, and the S-EM6 have a better sense of speed on bass and high (better control, better musicality). 1+2 have beautiful lows but they don't go as deep as I imagine : EM4 or EM32 go further.
But, where I can be very honest and nasty on the sound signature because it's necessarily personal and subjective although I mean the sound signature is the first way to have more realism and also more neutrality.
Here I think the 1+2 are absolutely not neutral, not balanced and not realist on many things. The highs are too brilliant to be realist, cymbals are not as bright and not as sparkly in the reality IMO, but details are here it's sure. The miss have core and details, it's emotional enough for an IEM that price, but too sibilant. The low reach not all the frequencies, for me it lacks some details although the pretty 3D aspect. The resolution get to fast to show completely the timbre.
Currently I mean :
+ : 3D soundstage / highs detailed / precise and musical / fun
- : mids are too sibilant too be realist / highs are extended aggressively : lack of liquidity / lack of coherency between the freqs.
To my mind it's a little bit like GRADO sound signature and qualities when you hear it for the first time : if you like it you will love it, if you dislike it you will hate it. I will give more observations later.
