Hey guys! Not to steal any of Joker's thunder, but I got a few samples of the upcoming IEM's. The
CC51,
M31, and
M21 to be exact.
So far (I've had them for about an hour, so nothing detailed yet, and all this can change.) the CC51 is obviously the most balanced, although with a bit of a bass hump (there's so much more to say, but Joker's said a good bit already so anyone interested can read what he's said. I'll comment on the latter two of which he's said little, if anything, about so far.), the M31 has the most mid bass (kinda struggles with low bass) yet the mids are pretty forward at the same time, and the M21 sounds a bit more spacious than the M31 with less of a bass hump, and more distant (They don't sound recessed, they're just deeper into the soundstage, which probably explains the illusion of more spaciousness. Compared to the M9, the M21 seems like a bit of a sidegrade, with a different, less bassy sound. The M9 is a bit more detailed and visceral though (using UE tips, which are my favorite to use with them. Haven't tried other tips with the new ones yet. The M31's and M21's didn't come with any extra tips. The CC51 does, because the microdriver sits at the end of the IEM therefore the nozzle is kinda huge. And to anyone planning on getting the CC51's, avoid covering the vents with the tips. They sounded more compressed imo.)
The M31's are probably the perfect budget IEM for pop, rock, and rap (ie. most modern radio music), and the M21 is more balanced and better for classical and most jazz. Again, these are very initial impressions and should be taken with a grain of salt until I've had more time with them. Just haven't read much about either and stating some stuff about them since there's not much said about them. Especially the M31, which I'm quite liking for what it is.
