If you're gonna go to the US, then I strongly suggest testing out the Shure SRH1540; Shure's flagship close back, full-sized, headphones.
It has warmer Bass/Sub-Bass & lower-mids instead of perfect neutral, but never bloated, muddy, nor over-exaggerated...
Highs are crisp, clear, and present; no piercing highs.
Easy to use as on-the-go headies listening at 46Ω Impedance and 99 dB/mW Sensitivity, but with any headphone/IEM's unless one is using a decent Hi-Res portable source (Hi-Res DAP like the Onkyo DP-X1A, etc.. or a Hi-Res mobile phone like the HTC 10 or LG V20) a portable head.amp will always provide even better sound.
Constructed from Aircraft-Grade Alu & Carbon Fiber make them ultra lightweight and uBer durable too.
And then there's the perforated alcantara earpads that are just THEE BEST EVER.
I mainly use my SHR1540 at the office with a balanced cable to the GeekOut v2, and it tackles everything awesomely: From EDM to Prog-Rock to Acoustic.. Actually listening to Run The Jewels as I'm typing this post
.. and the track 'Talk to me' just started, and it's bass is like being in the club!!!
If you're around Centurion, you can PM to arrange for a session.
