Tweet, tweet, tweet - the Bird is in da house!!!!
First up - I know people won't be happy with the package, but I care not for fancy boxes, so this suits me well. Wish a more travel friendly case, but otherwise no complaints! This listening done with the 1A, midnight tuning and E region.
Most of my impressions are going to be comparing with the Odin's - as I've been listening to that mostly over the past few weeks. The initial reaction is how laid back the IEMs are - in reflection the Odin's upper mid really is too pushed forward and definitely much more fatiguing than the Bird. No loss of detail on the Bird, but a very different presentation.
My first songs to test are electronic - and the bass really is a surprise with the Bird.
Almost as good as the Odin, but with the speed on many tracks you'd not be missing DD. Scary that. I think it's because the Odin lack the sub rumble that the Z1R has which is much more distinct when you're listening to music. Treble is not as peaky and possibly not as much extension as the Odin, but much more cohesive and far more enjoyable with the Bird. Overall it's close between the Bird and Odin in the electronic genre - do I want to be full on in, or more relaxed? I suspect in the long run the latter as detail is a tie.
Moving on to Jazz - this is where the Traillii wipes the floor and leaves the Odin smacked and buried. To be fair, I've never enjoyed the genre with the Odin, much preferred the Z1R, so I expected this. Far more enjoyment, cohesive and outstanding imaging and incredible timbre. Oh and vocals which were in my opinion pretty average with the Odin. I need to listen more, but I'd still give the Z1R a bit of an edge with soundstage height. But width and depth goes to the Bird. I guess the general theme however is the enjoyment of the music and emotion. The Bird does this effortlessly and as
@HiFiHawaii808 warned me, end game level for Jazz .
In summary, the Bird tuning is really excellent as I do prefer a mild V in my graphs. I find the Odin's a bit jarring at times now, but lets see! So more listening ahead!
