Can i ask what’s the name of that keycap set?

Sure you can ask, it's GenesisPC red line theme keycaps. But actually they're Kon Momo clones

i bought clones xda profile from alli and found them very wrapped, especially spacebar

AliExpress is a big no-no for me

I think they are the same just selling in different places, check your spacebar on the table

What a fantastic pink!

But it's closed back isnt it? How does any sound get in

Even if headphones are closed back, they'll still let atleast some outdoor sound let in, always. If that needs to be completely blocked, noise cancellation is necessary
