Radius HP-TWF21

Able Planet?

I tested the Denon ah-c300, the bass is simply wow

NOCS dual dynamic NS600 Crush

which one is the cheapest?

MP4Nation Brainwavz R1 promotion @ USD34.50

use the promo code get another 5%, haha, but i dunno what the code is already.. forgot

thats dirt cheap

Here you go, try to name them all:



I have the new NS600 Crush coming in as well, but currently stuck at local DHL office as they want me to pay tax first. Will have to go and collect it on Monday. R1 will probably come sometime next week as well. The new Denon is a bit too expensive for me at the moment since I need to spend money elsewhere, but hopefully I can save up enough for a pair early next year.

Is it obvious that I am a bit of a dual dynamic fancier?

It's also my dream of collecting them all. My first and only dual dynamic was the HP-TWF11, a.k.a DDM. Loved the bass and mids. The treble made electric guitars sound a bit veiled and "underpowered" though. For piano, cellos, acoustic guitars, or any other organic strings they sound wonderful, and so do drums. Great when paired with my Fuze+, and not so great with my Hifiman HM-601 (although it improved the bass presentation).

I'm aiming for the JVC, the Fischer Audio and the second gen from Radius, or any updated models. My first priority ATM though is building up my body, so those would have to wait.

The Muramasa is sadly cancelled, since its asking price is just absurd, and the production cost exceeded their expectation.

EDIT: Grammar fix.

So it's just like the DDM, only with a slightly less fancier name.

That's an impressive collection of Dual Driver Monitors

Beside what has been mentioned, there are also Fischer Audio Tandem and the vintage Panasonic RP-HV600 in the picture. Technically HV600 isn't a dual dynamic, but dual diaphragm single dynamic (talking about vintage - AKG K270 is a full sized dual dynamic as well). The white and silvery grey one is Sonocore Cindy.

Beside Able Planet and Brookstone's Clear dual drive earbuds, which used the same type of driver as DDM, there is also Moshi Audio Clarus. They are using what I call 'Polar Co-Axial', since the two drivers are in polar position instead of facing the same direction like typical co-axial.

Added on October 13, 2012, 10:41 pmForget to add: Ocharaku Flat4-SUI - this IEM uses one of the dynamic to cancel unwanted peak and resonance of the other. Kind of weird of how it works and it is also very expensive (>US$400)

I feel there are more Dual BA then dual dynamic IEM.

Yes for sure.

Here are just a few I can think of:
Apple dual driver (ADDIEM)
Audio-Technical CK10, CK90
Brainwavz B2
Creative Aurvana In-Ear 3
Earsonics SM2 / SM2 V2
EXS X20
Fischer Audio DBA-02 / DBA-02 MK2
Galaxy Audio EB10 (same as OSP EU-6)
j-phonic K2 SP / MX
JAYS q-JAYS
Klipsch Custom 2 / Custom 3
Phiaton PS200
Phonak PFE232
Rock It Sounds R-50
Shure E4c / SE420 / SE425
Sony XBA-2
TDK BA200
Ultimate Ears UE700 / super.fi 5 pro (same as M-Audio IE-30)
VSONIC GR01
Westone UM2 / W2

... these are not counting dual BA custom and some universal trhat I can't remember / don't know, you can see how long the list goes.

Oh, forget to mention another dual dynamic - Koss KDE-250

They are easier to make as they are smaller.

but more pricey

Added on October 14, 2012, 11:43 pmif single dynamic IEM the list will be as long as china great wall
so far is there is a list of IEM?
Maybe can enter Guinness World Records
@ Clie OS ur collection maybe also can enter Guinness World Records

Added on October 15, 2012, 1:31 am14 Dual Dynamic IEM vs 34 DUAL BA IEM

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?

This post has been edited by tunertoobe: Oct 17 2012, 11:15 PM

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?

This post has been edited by VagueConcerns: Jul 26 2014, 01:24 AM

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.

Necromancer level 2

I'm having a hard time recalling and describing it.
Sometime the sound gets veiled, and then you can hear the two drivers each doing their own thing. I can sort of hear them "splitting up".
Incoherence is the word I think.

If I remember back the music I listen to when I notice it, it is somewhere in the mid frequency, but not sure of it's at the high-mids.

man, my TDK IE800 just lost sound in the right side. Anyone knows how to go about repairing it? I suspect its the cable/wire at the 3.5mm plug thats causing the problem. Because random jiggling of the cable there makes the sound reappear.

http://www.radius.co.jp/en_product/hp-twf31/

http://www.radius.co.jp/en_product/hp-twf41/

Yeah, went to their website a few days ago to see how they're doing. Those things look cool. They're using piezo now, but still retain the "co-axial" driver arrangement.

I tested out both model during CanJam Singapore 2016

HP-TWf31 more relaxing bass extension so far the best IEM I had listen deep and low end frequency.

HP-TW41 too much of detail analytical but for sting instrument can fight Shure KSE1500
bass extension deep and low end frequency same as HP-TWf31

Nice. Pricing?

i also remember hearing them at canjam, really not my thing so i cant comment too much

i haven't gotten myself to use my mee xduo gold until now, it's a dual dynamic

1.5k+- ~ 2.1k +- MYR

This post has been edited by wkkm007: Mar 23 2016, 12:57 PM

Japanese or China?
https://www.cool3c.com/article/104128

Where got selling it ?

we met the maker so we know what we are talking about, especially canjam attendees like me and wkkm

and the official website didnt give it away for you right?

Cause never heard it b4, just simple search on google as well.

But just forget it..

I remember the joy and horrors of owning the first DDM. Great sound, weird sound stage, horrible ergonomics.

Listen to the new Radius on CanJam as well. Not particularly impressed, especially considering the price.

Maybe they tried a little too hard on their new offerings.

Rose Technology Mojito

More on the sound, perhaps? Can't find info on this.

It is a super expensive (>RM900) dual dynamic earbuds, using vintage Panasonic bass driver. Neutral, airy, super detail and widest soundstage of any earbuds I have ever heard.
