Just Incredible.....End Game in IEMs!!!

If you need the best and can afford it.....don't look around for anything other than the bird. No doubt these are expensive, but once you start using it, right from out of the box, you will realize that you are in for something which you have never experienced earlier. High quality planar full sized headphones sound from an iem when used with right gears and ear tips...You will feel sound not in your ears but all around you streching above your head. Such is the spaciousness, stage, imaging detail, layering and clarity. Now whether the asking price is justified for this sound quality is something for one-self to decide....This excels in all departments and is a TOTL iem for its sound quality. If you are in look out for best of the best in the market...this is it.... Big shout out to Andrew and his wonderful service . Got the shipment in shortest possible time delivered in India...

Oriolus Traillii JP New Generation Electrostatic Hybrid IEM

Perfect example of, "less is more".

Oriolus Trailli finds its strength in being tonally accurate, properly tuned and demonstrating vast open staging. Traillii isn't exciting in how it portrays sound, its excitement comes from how it makes no mistakes in doing so. Many have been on the hunt for the 'perfect' IEM. The search has always been for the one that does everything better than anything else. No one seems to have expected that the best sound they'd come across would be in an IEM that bests everything else by NOT doing everything; rather doing everything well, with seamless execution. The perfect example of less is more.

Overall delivery is a warm, neutral sound with fantastic clarity. The extension seems infinite and is the only IEM to date that has never sounded compressed in any frequency range. This comes from the extreme width of the midrange

New best friend

I’m thrilled with the Traillii. The sound is impressive, the fit is perfect, it is light, and I will say that I like gray colors and not noticeable iems, but in this case the red plate looks great.
