i have no idea, i just have a brief hands on with them

The comfort improves greatly over the old elite. Sound wise its almost the same, just that for the old elite its harder to get a proper overear seal. Sound leans towards the bass. If you like your game and music to have a bass boost then get this.
9H has bass but not as much as the elite. But for me i prefer the much more balanced sound of the 9H than the elite.
Of course elite do have the better bling bling factor

a comparison with normal mkb would be good. the only few things that i guess are since it has low-profile keys, perhaps the feels will be like those membrane-based apex. i believe the win key lock is still there, as in apex. maybe there will be additional sets of keycaps from ss that we can replace stock ones with those.

i am using corsair k70 rgb (red swtiches).

sweet man thanks a lot for the tips where did you test it by the way?

yeah i'm getting used to k70 for gaming, but i kind of miss the feels of apex, that's why i thought of getting some inputs about m800 (the low profile keys should have similar feels like apex). you're right, it's better to have some try-outs first.

the only thing i dislike about apex is sometimes the keys are like 'hard to push due to frictions' (during gaming. i don't know how exactly to describe it properly). it's fine when i type (to me apex is very good for typing).

premium mechanical keyboard 
prism raw sounds great, i just dont like the build. Plastic feels cheap compared to the v2

this promotion valid to all the countries if no mistake. i'm thinking of sensei raw. either get it from local or amazon US.

Standard version.

Lol. Was just referring to you not being in selangor. No need to be so insecure to show like everything you got.
