FLC Technology FLC8 and FLC8s Impressions Thread

[ldo77]

After less than 2 years, my flc8 have a problem 

I have a lake of low in the left side ... maybe the dynamic driver is broken.
I tried to contact LMUE and they propose to repare it for 150 SGD ... Ouch.

I thinlk its too expensive for a 2 years old iem.

Are the filters in place and secure?  Some people have had an issue with the tiny washers becoming dislodged.

Lookie what I found in the mail :tongue_smile:

It sounds way more impressive than I recall from the tour that happened way back when, and the improvements to the cable are to be applauded. Fit is greatly improved without the memory wire (for me at least).

I blame Nik for my pair...after using his along with the wonderful synergy and the Shanling M5, I went searching. Found a pair of FLC8S on eBay, which were at a substantial discount for a barely used pair. Only downside was one cable and the memory wire cut off. I have since found, and am currently listening through the excellent x5iii with a used cable I found WITH memory wire.

I am a happy camper.

Told ya B9Scrambler long time back, get the flc8s and you will forget all the kz iems etc but u got into a heated debate instead. Now your FLC8S will probably make your kz iems sound crap. Enjoy. Your next step is Andromeda/A91 or end game Zeus R.

Alternately, @B9Scrambler can enjoy the FLC8s while also enjoying any other IEMs he likes, and consider any upgrades in his own time if or when desire and budget permit.

What's the problem? The left has too much bass?

 

[Flcforrestwei]

OK, Forrestwei...now that you're on here...c'mon, toss us a few bones...when should we expect
some announcements for the Celeste or other products coming down the pipe?
we want to support you, sell our kidneys, 2nd born and such to pad your pockets. 
please don't disappear without giving us some juicy morsels....please.  

Celeste had a dramatic modification, we are making samples of the new version, should have some from Canjam Singapore.

thanks, Flcforrestwei:
 
hey i know this is a stretch, but would you ever consider adding ADEL technology as an option?
the more I read on this tech (and from those who have had it in their iems) the more I'd be willing
to pay more for it...as an option.

Excellent! Thank you for the update and the wonderful FLC8S. Quite happy with mine.

Much respect for checking out the competition and giving a little comparison! Other manufacturers can learn a lot from you. Having a variety of products on the market is basically a win for customers and manufacturers alike. If all manufacturers described and compared their products properly, finding the right product wouldn't be such a pain for us customers. Thank you!

having heard the flc8s way before the A4, the tuning of the mids and highs is masterfully done. If I were to underline key differences, one is more cerebral (very good cerebral ofcourse) and the other being more my go to toe-tapper.

To be honest, this is the first time I have heard ADEL technology, and I just searched it, and I think I know what it's (maybe not 100% right).

Almost IEM has a leaking system, most of them is a small hole, some of the are filter, FLC8s is replacable Sub-bass plugs.

The ADEL technology emphasis on leaking and isolation.

Most of people worry about the leaking system can cause isolation issue, the system can cause isolation problem? the answer is negative! you know, the system can only leak the sound under 80 Hz, that means the sound over 80Hz from the IEM can not escape from the system, how the noise outside can go into the IEM from the system.

Below is cross section of FLC8s, the hole on the sub-bass plus is 0.25mm, if noise from ourside goes from the system to the ear drum, it needs go through the 0.25mm hole, then, the long channel of the IEM, then, the little hole at the side of the nozzle, then, long ear channel. Human ear is impossible to hear it.

Nice to see Forrest contributing here.  Hope that becomes a regular event.

thanks for your reply, Flcforrestwei...my impression of ADEL is it acts as some secondary eardrum passage or such...
that by not plugging the ear passage there is less pressure placed on the eardrum, thereby helping to avoid
possible hearing damage.

I know that the very pricey $2700 Empire Ears Zeus Adel XR has it
https://www.empireears.com/product/mto-universal-zeus-xr-adel/
(when you open the link, scroll to bottom as there are some pics of the ADEL modules).
 below in quotes is what they say about it:
 
''The Zeus-XR ADEL features the world’s first and only patented technology that safely delivers a louder, more spacious and richer sound – all while avoiding the risk of hearing damage caused by in-ear monitors. When the ear canal is sealed by an in-ear monitor, the driver vibrations create harmful pneumatic pressures in the confined space. The ADEL technology features a secondary eardrum that absorbs the pneumatic pressures produced by in-ear monitors and provides a much safer listening experience. It delivers sound the way it was meant to be heard. With the ADEL, bass sounds deeper, midrange is clearer and highs sound richer than ever.''
 
(in addition, all those who replied to me on the Campfire audio Vega thread, and who've tried Adel in other earphones, give it a huge thumbs up:
some have told me that they don't have to turn up the volume as much, either...also good for one's hearing long term)

Read the whole thread about ADEL technology in sound science forum and I don't really see a big advantage over a vented hole because the Celeste will already come with tuning capabilities and a vent for dynamic driver. I think I know what they are talking about when they say "pneumatic pressure" that happens with IEMs that are not vented. Happened with andromeda when I got them and when you trap too much air, it creates the situation that ADEL technology solves. However, when the pressure is not equalized you can tell because sound gets heavily muffled and fit becomes very uncomfortable. This can definitely be avoided with the right size choice of tips and careful insertion. I've had no problem with my andromeda ever since I got the right sizes for my spiral dot tips and it feels no different than inserting flc8s which is vented.
 
I guess it would be best to make the option for buyers since there will be yays and nays for purchase.
