A Titanium Masterpiece

I'm not going to wax lyrical about the Traillii Ti here because it's been perfectly adequately done by others in this thread. I wholeheartedly agree. What I would like to say though, is that I have a deep appreciation for the complete lack of bling. The Ti does what it's supposed to do: sing - and it does so clearly and articulately, with great control, layering, and positioning. The price of admission is eye-watering, but what you get is overall, the best I've heard packaged in solid, wonderfully understated, durable earpieces. If you're able to pull the trigger, you won't regret it. Enough said.

the legend of the bird continues...

Let's start off with CONS:
1) Oriolus only grace the world with only 199 sets.
2) Heavy. It's heavier than OG Traillii and UM AP combines.
3) Pricey.

Love the L shape terminal from new cable. Cable looks very familiar to the PW1960. New cable material consists of pure silver, gold-silver alloy, copper vs 1960 pure copper.

I thought Traillii was perfect. Oriolus somehow manage to improve the vocal and treble. Traillii TI sounds like an open back headphones...very airy.

Warm natural sounds when pairing with Sony M2.
Turn on Hyper and let the bird with titanium wings sings to you if you have Cayin N30LE.

Beautifully retuned Traillii for different flavors!

Traillii JP owner here since the release and still love it to date. Traillii Ti is a subtle but significant "retuning" of the OG. I say retuning because the resolution and overall technicality sound very similar. But don't let this comment dismiss the Ti because it has refinements in the area where OG might have sounded a little too soft. The bass has more sub-bass focus, less mid-bass, and overall tighter and faster. As a result, the mids come through very clean, especially the vocals. Instead of the lush in-the-mix vocals of the OG, you get a clear vocal with plenty of air over the instruments. There's exceptional clarity while maintaining the musicality Traillii is known for. The upper mids to treble is still sibilance-free and well extended. With Ti, however, I hear the close-in treble air better (e.g. air around cymbals and upper registers of pianos and horns) whereas the OG tends to extend the space wider and deeper for a grand soundstage. Overall, a complimentary tuning to OG, especially f you found the OG soft and dull.

Thank you MusicTeck for bringing this wonderful piece to us!
