Anyone else had a listen yet? Got my TWF31 and so far I'm impressed! especially about the quality of the highs. i can believe this is an older sibling of the TWF11 but the amount of improvement is just ridiculous. only possible issue is fit, which i'm still trying to figure out with these crazy bulky shells.

well i did it. took a look at the price on accessoryjack, probably never gonna get this chance again :/
@DimitriTrush from MusicaAcoustics right? did you stop selling Radius IEMs?
Had an old Radius flagship from years ago, and really enjoyed the sound then. Probably bought that one from Dimitri. Not sure if the sound difference is worth the extra $100 between the TWF31 and TWF41, thoughts?

Can't help you choosing between the TWF31 and TWF41, since I haven't heard the former. But I can at least say, that compared to the older TWF11 and TWF21, the TWF41 is a considerable upgrade in clarity and refinement.
I want to buy this but made in China.......

Radius is a Japanese company, and as far as I understand they own a factory in mainland China which means they dont use any OEM manufacturing, an example would be Brainwatz or Fisher Audio, which orders to a large OEM factory to make they earphones. In recent years Radius quality control has increased because there is just no way they can do otherwise, japanses customers will not tolerate any quality issues. in 2012, 4 years ago, Radius faced issues with the THW-21 IEMs. for those who dont know, this was companies 2nd flagship released after the TWF-11, So Made in China does not mean quality is worst then if it was made in Japan. Only few IEMs manufacturers are making earphones in Japan today, such as Ortofon, JVC, Flagship model from Final and Sony as well as Fitear and other few other 1000+ headphones from Audio Technica and Pioneer.

OEM is a massive problem that no one think about. I am on the edge of getting this or say the money for the CustomArt Massdrop Exclusive - Ei.XX CIEM
I wish there was a way to demo expensive items like this before committing to buy

You may still audition this if you are willing to travel, how much travel depends on your location. , so obsviolusly not talking about Japan now.. Radius team has traveled to European and Asian CanJams during this and last year. They are still planing to do it this year in UK and Essen Germany as well as Denver Colorado. This are your best bet. But I can pretty much assure you this price you aint going to get this elsewhere and this is probably last chance as USD currency dropped against japannese yen so things will only get expensive for those living outside Japan.
Are they made in Japan?

designed in Japan, factory location in China

Thanks for the information.
I've had the TWF41 on loan for a week. They're technically capable IEMs that remind me of British speaker sound in some way, smooth and warm-ish, yet still exceptionally detailed and delicate. I'd consider them an upgrade to the KEF M200 in a similar vein, or a possible IEM counterpart for those who love the HD650. Fit is pretty much downward only and can be a little tricky though, but overall I think these would deserve a little more attention than they get, particularly from people who are into this kind of sound signature.
I was hoping the flagship color was black and more importantly it would be 299 USD. They are quiet large item, as much as I like to open Japanese IEM I am not so sure about TWF41.
Thanks for your review and thoughts @jeffri and @nangryo. These really do sound like older siblings of the TWF11 and 21 from what you're saying, with a piezoelectric instead of dynamic driver for the highs now. I love the styling, detachable cables, and that they've kept the case which is still the nicest clamshell I've seen for an earphone. The only thing holding me back is the price. And it's still not exactly clear what the difference between the TWF31 and TWF41 is or if it's really worth $100. So i'll just wait to see if anyone comes up with more comparisons :) the only other info i can find are people's impressions from demos. https://forum.lowyat.net/topic/2546055/all http://www.head-fi.org/t/798892/radius-hp-twf41-w-n-4-price-drop#post_12381243

Indeed, $100 is quite steep. In my local store, the differences isn't that big (about $75), so it's an easier choice. Anyway, looking on the radius site: http://www.radius.co.jp/en_product/hp-twf31/ http://www.radius.co.jp/en_product/hp-twf41/
I just noticed the differences is that 41 uses beryllium coated diaphragm, while the 31 uses film. I guess that is more exotic material in use here to warrant the price differences. ;)
Anyone tried these and the Audio Technica ATH-CKR9/CKR10? They are also in the "dual driver" category and are both from Japanese companies so this should be an interesting comparison. I love the CKR10's btw.
TWF31 and TWF41 both has balanced sound and excellent staging, resemble open back headphones, courtesy of the piezoelectric driver. TWF31 has freq range from 10-40000hz, whilst TWF41 is 10-45000hz. TWF31 has more warmer darker sound than it's sibling. Both has smooth midrange and high. It really is smooth unlike BA sound, but yet still detailed. TWF41 has more detail in high notes than it's sibling. Bass is good on both iem, has enough impact and focus. Separation for each instrument is also good for both iem. They good for jazz and live acoustic music, but not so much for metal or aggressive fast paced music
This iem is so underrated. Sad. a bit pricey though, but I think well worth it
How is the frequency range so good?? The dual drivers?

Have you listened to Dunu's Titan 5? Or DN-2000? How would those compare? They are far cheaper...But if the quality here is better, I'm ok with spending more. I'm looking to replace a pair of old Shure SE115's (looking for an upgrade).

I heard one Dunu headphone in recent meet, but I forgot which model it is so can't help you there. The Dunu I heard is bright sounding, to the point of being quite harsh to my ear. But again, it's a very short impression with model that I have forgotten, so please take it with a grain of salt.
Another IEM to consider that I owned is Echobox Finder X1, it's cheaper at $199 but has the best build quality out of all IEM I owned (FX850 is close second). It's very small, comfortable and sealed extremely well. The sound is on the brighter side, midrange is quite thin, sometime dry and harsh, but bass is powerful and hit with deep impact. It has 3 different tuning filter to customize the sound too, although it mostly affect the bass region.
Anyway, they were all different sounding and has different trade-off. X1 is my on-the-go cans due to the form factor, but when I'm sitting and relaxing, I'm reaching for TWF41. I loved the smooth sound of it. :)
Wow, never expected to see this here. This is a very good, smooth sounding IEM. I have the flagship TWF41. I write review for it in my blog if you are interested: http://jeffri.me/2016/06/a-bold-but-very-smooth-iem-from-japan-radius-hp-twf41-casual-review/
I can't find any reviews of these anywhere - can someone tell me more about these IEMs? Is this price good? Has anyone listened to this model before?

The old Radius TWF11r was my favorite IEM for years and was an incredible value at ~$160 six years ago. not so much now... pick a $60 IEM today and it'll handily beat it. Then the TWF21 was released with an updated design and even higher price but it was supposedly just marginally better, with a slight shift in sound signature and better fit. No one has really talked about Radius IEMs since those 5-6 years ago. I heard one comment about the TWF31 a while ago though, but nothing more than "it sounds good". I don't doubt that, but just really question if it's worth the high price now.
