Just received today my pairs of Willsound MK1 & MK2 (both rev 2) !
Build quality is very good, but in favor of the MK1 (in a beautiful red cable and better finish, while termination jack looks better on the MK2).
On first listening, clearly, MK2 wins. I’m a bit deceived by MK1. I hoped better.
MK1 is clearly designed for relaxing listening (no clarity, not bright, thin soundstage). Looks better for pop musics I would say as well as Piano, instrumental, etc, while MK2 is more balanced and for all genres (EDM also). MK2 has a very good (but not exaggerated) soundstage but both earbuds compared to EMX500S definitely lacks sub-bass. EMX500S is always the most complete sound, the only thing I don’t like is the “extreme” soundstage (a bit like a 3D sphere), but excels everywhere and sounds like full headphones due to sub-bass being present.
I really enjoy currently MK2 sound. Even if it lacks sub-bass, they a still slightly more present than MK1.
MK2 is an all rounder earbud. It has the most impressive listening experience (from all my earbuds).
It has the right amount of everything and lacks nothing. MK1 is more dark sound I would say, it’s more boring but at the same time for very long listening experience, MK1 is still good tho.
MK1 is another grid than the most commons EMX500S & MK2 grids (will maybe take a photo to show you guys if interested). I don’t know if this grid muffle a bit the MK1 drivers, I’m pretty sure it could express differently with the same MK2 grill.
For now, I can’t say which is my best earbuds, but I’m pretty sure that my MK2 will be. Too bad for the sub-bass.
Foams placed on earbuds are the best sounding experience from any other included foams. They are black and extremely fragile (very very thin and spaced, to let the sound express better with a good comfort). These foams looks similar to original Monk+ foams.
They are so fragile that I already damaged very slightly two foams (even if they are still ok, too bad there is no other set like included with the same thickness).
Will try to do a further comparative with EMX500S / MK1 / MK2 (and maybe Blox BE3) soon.
Cheers’ and happy listening
