I don't have too many, but its really nice to have different flavours. Also switching to a shitty headphone now and then helps me appreciate good music which will otherwise be taken for granted :)

Yamaha YH-5000SE looks super cool. As already mentioned Raal, HEDD phone, ZMFs but all of these are expensive.
Ones I wanna own for looks is Fostex T60RP, and Grado RS1x.
I see some listed for sale in head fi. I sold mine to get money which wasn't a smart decision in itself.
N3 has the sony house sound and very delicious bass. And enough details to not miss out on anything. The fit is bullet which wasn't the best for me but everything else including the accessories are great. I suck at describing sound but they made me love base, and also discover so many details that I didn't before, even with er2xr.
Also if I remember well, the stage is narrow n layering of instruments isn't great. I think it will be noticeable if you get to compare with s12.
Enjoy! I recently got myself a pair of Kiwi Ear's Cadenzas and I share the same excitement. I am preferring them over everything else I have now, in the honeymoon phase now.
The only IEMs really left on my bucket list are the Sony XBA-N3 and Letshouer s12 pro
I have had both. N3 is one of my all time favourite! s12 pro was impressive but not for me.
560s is really nice, and looks awesome too.
openback - HD600 with cavalli tube hybrid :)
among iem - Shure se846 with Cayin RU6 as source!
iem: Kiwi ears Cadenza
amp: little dot mk2
Its good but after having a pair of Andromedas, I feel like hd600 is missing something regardless the amp/dac I pair it with.
