Hello,
Based on various reviews and tests - i BOUGHT AN ORIOLUS TRAILLII recently - it was -1000 USD discount from normal price, still a bit high but well - it's an almost life time decision - i plan to use it for many years to come. I listen 3 times a week for 1-2 hours and calculated that over the next 5 years this IEM will cost me around 10 USD per listening session - that is less expensive than going on Netflix or any other channel or even to buy concert tickets - and MY advantage is that the sound stage is almost as good (without audience of course).
Now I use the Traillii with a Luxury and Precision W1 DAC which is at a very reasonable price (and can be bought from the same company in the US as the Traillii) and which has outstanding sound qualities - these two get driven by a simple Huawei P30 pro smartphone with FLAC files of different recording resolution - from CD quality to 32Bit/96Khz - and i can only tell - this sounds absolutely heavenly !!!!
So yes, things have a price - but think of it - Oriolus put 12 !! drivers per side and they use a much better plastic material than acrylic AND they use a super cable also - Iam not Japanese nor do I get any benefit out from writing nice things about Oriolus products - it is simply the case that not many people outside of Japan use this IEM and so thought to share my experience with it. I am blasted away with this sound quality and can only confirm to buy a Traillii if you look for something with 3D sound.
Last point - my reference point is a A&K T8iE-Mk2 (now called Beyer Dynamics Xelento) which at 1200 USD is also already on the high end side - but this is no match whatsoever to the Traillii - sorry Beyer Dynamics...
I’m actually already convinced by the SQ of these monsters, they surely sound fantastic! The best I’ve tried so far For IEMs. But honestly I just feel the price hard to justify when you can buy a brand new Focal Utopia for $2400 here in China!!
I also have the T8ie II and as good as they are, they definitely don’t even compare to something like Traillii, i4 or Erlkonig. BTW, Xelento doesn’t have the same sound signature if I’m not mistaken, even though they look very similar.
