What'd you feel about the Storm vs Trailli OG?
Let me chime in if you don’t mind folks - I was also able to attend recent Amsterdam meet up where it was possible to compare side by side. I was listening to OG Bird with stock PWA 1960 specially tuned cable while storm had ultra-premium Sovereign Symphony cable attached to it.
Ergonomics wise Storm shells are a bit bigger and heavier. While it wasn’t an issue to me Traillii shells felt a bit more comfortable to my ears.
Talking about sound first thing one might notice is that Storm soundstage is more rectangular, it’s like listening to a proper 2ch system, while Traillii stage is more of an oval one with it unique presentation and separation which is applied to all the recordings you listen to them through.
Both wide and deep enough when properly powered, but I believe that Storm needs something closer to 1W at least to shine properly - I was using DX320 MAX while others also prefer say external amps like PB5, so it speaks for itself I think.
Storm overall sound is more reference and more technical, while not being dry, soulless or lacking in weight.
Sub bass is strong, textured and very well defined on the Storm. It is tastefully elevated but to a bit lesser extent than Traillii ones.
Storm mid bass is much faster, hits harder and will not provide that slow, pillowy feel that Trailliis mid bass will provide.
Thus leading to Storm lower mids being clearer and apparent, while Trailliis have more weight and density. Upper mids on Strom are both not elevated nor recessed sounding more present and natural than a bit recessed ones on the Bird.
Overall mids on Storm come as more even and effortlessly detailed, probably due newer generation drivers used, like on say Fei Wan.
Traillii mids are more romantic and lush though.
And here we come to a deal breaker, at least for now and for me - to the treble.
All we know that Birds treble doesn’t have any harsh peaks, sibilance, but instead has great air on whatever you listen to it.
I’m a bit treble sensitive person and Storm comes as hot to me in the cymbals crash region even while using Eletech Baroque eartips. This also does detract from 3D stage holography to my taste. As for the rest Storm treble is pretty neutral.
As a conclusion I would pick up Storm as an upgrade to OG Traillii if you don’t mind using it with powerful sources and cymbals along with Storm fit are not a problem for you.
Otherwise the great and mighty Bird is still a top choice even if nowadays its details comes as a little less apparent in comparison, especially if you like its rich and soulful presentation.
Hope this helps!
