They are easier to make as they are smaller.

but more pricey

That number may increase. As smaller dynamics gets better and better, manufacturers would be able to fit more into a single housing and possibly make multi-driver dynamics much easier and therefore more common to manufacture. Dynamics may have a ceiling (a limit) when it comes to size, I don't know. The smallest right now IINM is from HiSound Audio, the Crystal, at 5mm. Reviewers everywhere are raving about how good it sounds. Of course it doesn't have the bass to match bigger drivers, but I'm sure a few wackos out there are working on that.

Anyone tried Ah-C300 before? Very interested with that new Denon subwoofer beast. If the bass isn't overpowering the entire FR spectrum, then I might consider it.

Two 11.5 mm dynamics per earpiece.....damn.

Wow, that cool.
Off topic,
Denon AH-C400 MUSIC MANIAC this also another hot babe. Dual BA

Why does Denon claim that the AH-C300 as the world's first dual dynamic IEM?

I think they claim it was their first. haha. But i'm really intrigued... How can they finetune their house sig into a bass monster.

We all know quite a few had already done it.
Panasonic made the first ever dual dynamic 'earbud', while Radius made the first dual-dynamic IEM.

I'm not even sure if they're the first with control-talk. IINM there's a DDM2 knock-off that has control talk and dual-dynamic as well. However having all the controls and even the mic at the earpiece itself is ingenious. Imagine that you;re taking a call and pressing on the earpiece. It makes you feel like a Secret Service agent.

Oh and BTW, I looked at the price of the new Brainwavz R1....oh yes I'm gonna get one. As soon as someone brings them here though.

Judging from this review, I assume this is "V" shape sounding?
Slightly tempted by the price (USD 34.50), can be under RM150 here if anyone does bring it in.
But from the official picture, the plastic looks a bit cheap? hehe Though the cable terminating end does looks good.

Heck, it's a dual-driver priced under USD40, something has to look cheap otherwise they're making it at a loss.
It's a dual bore design too, so that's unexpected from something at that price.

I personally tried it for a while. It gave me quite a pleasant bass response. Sufficiently good bass, and quite balanced signature.

I'm interested in hearing the unique melody 3dd. Too bad no demo set/dealer in Msia

Radius DDM = Dual diaphragm Matrix
It isn't 2 dynamic driver, but 1 driver 2 diaphragms. So, kinda awkward here LOL.
Latest version is TWF-22r (on my ears now )

IEM:
Havi B3-Pro1
Powerbeats by Dr. Dre

Well yes and no I think. Yes they share the same magnet, but still each have their own voice coils.
I'm still unclear about the usage of a crossover though. But the "smear" (but really just an aggressive dip in that freq range which sounds a little off) in the high mids in DDM1 suggests something more than just simple parallel wiring. There's a "frequency divider" according to Radius, is that the crossover?

Aggressive dip in frequency range? Is there one? I didn't notice with this one now. Can you tell me more?

Yeah, the "frequency divider" looks very much like a crossover, but according to the picture, it looks like a magnet or something. I'm not proficient in speaker technology either.

But certainly, they claim it sound like hall. This one I think they achieved their objective. It really is spacious. Deep and wide with the reverb.
