Btw, did you message the seller if the pin-outs are compatible with your model player? If not, you can ask them to resolder the wires to your specific player's pin-outs!

Cowon Plenue D2 diy modded, stock sound was crap, after mod sounds like a high-end desktop amp!: https://www.head-fi.org/threads/new-model-cowon-plenue-d2.896733/page-39#post-15138483

It's all good, my mission was to find the Ultimate Hi-res sound on the Go portable, that beats TOTL full size headphones/amps! At this moment it's the EP05 and Pure silver cable combo, just waiting for the true bio-cel drivers coming to reveal the ultimate truth,

Its thicker than the stock cable hence better flow, but stay silver plated copper with the interference transistions/colorisations between silver and copper conductivity. To me with that the copper colored the bass bloat/bloom into and veiled/obstructed the mids/highs flow= not natural/harmony...

This combo is so amazing! I can wear it literally 8+ hours at work, even with openback it has better noisecancelling effect than real ones due Hi-res SQ and full clear bandwidth FR without sound-fatigue. Currently running/enjoying/swinging through my 21500+ soundfiles, never heard this heavenly...

Try the EP05, the unique open back tuning make it sounds natural flat response full bandwidth with clear mids, if you comes from v-shaped buds then the EP05 considered sounds like n-shaped, but it not all highs/bass are intact, just like flat/neutral best soundings buds. Search for other $16...

No, see pics above, just the normal 3.5mm 3-pole plug in 1.25m for High-End SQ on the Go with all the common gears: nintendo switch, 'lo-fi' retro game consoles, smartphones, hi-res player, laptops, ps4, xboxone, 4k uhd etc. Its sounds so TOTL, just ordered another one. I'm in awe it just opened...

Yes, it's possible. Now the tech behind, these are multistranded 'in balanced mode' pure silver wires where the higher freq. can travel more freely without obstructed by the lower freq. like it will happen with 1 solid core silverwire, where the bass intermodulate/obstructe/overwelm the highs...

Got the pure silver cable: https://www.head-fi.org/threads/jcally-ep05-jc10-bio-cel-endgame-16-worth-1000.959655/page-2#post-16560211 The cable end has the wearable mold to hang up onto ear, the earbuds stays comfortable without slipping around and literally can wear it 24/7. Astonishing sound...

This guy got the real ones: https://www.head-fi.org/threads/jcally-ep05-jc10-bio-cel-endgame-16-worth-1000.959655/page-6#post-16585885 You got the fake ones, the good have strong bass rumbles, almost dark sounding like a full size hp. The fake one have light fluffy bass and distorted trebles...

Just throw the fakes away, I and the other diy guy proved there are fakes and different types driver messed up everywhere, the clue is on the lucky draw get the right ones!

Not impressed= fake. You got the fakes and with different back plate holes with different crappy sounding drivers 1 titanium and 1 pet= crap sound multiplied, just like this guy. https://www.head-fi.org/threads/jcally-ep05-jc10-bio-cel-endgame-16-worth-1000.959655/post-16567552 Very simple...

Try this out: Put connector/cable through the side hole if possible, cut ears if not needed...

Definitely fake, should do straight down 25hz/20hz, listen to test-video above, the fake one sounds: flabby bass/no deep rumbles and distorted smear trebles (no fast detailed cymbals), bad dynamics worth $3. Get the EP05: no fake found yet, I got 5x EP05 all 5x good, where-else I got 3x JC10...

For my search for the real bio-composite drivers without the roulette game, I found wysiwyg and ordered: https://www.aliexpress.com/item/1005002799509411.html?spm=a2g0o.store_pc_groupList.8148356.58.2a531d0d3xaBDJ

Bio-film Investigation Part2: OK, got another 2x EP05 from same seller. One set sounds exactly the same as the first EP05, so I open it up which damage the voice-coil wires. Other one sounds abit louder/wider spacefield/some shimmering/sibilants in the treble regions with same base bass body...

Smaller dots is for EP05 and bigger for JC10. If doesn't matter where from, it's mixed in any batch to any seller ali or else, read through the reviews, not enthusiastics ones got the fakes.

7 sets will come in few weeks time, I have the 1st 1x EP05 real, 1st 1x JC10 real and 2nd 1x JC fake. If I had the fakes first, then this thread won't exits!

NO, if it doesn't sound like a 'high end' fullsized full-range freq. headphones, just like generic earphones/iem/headphones then yeah you got the fake ones! If you have a good hearing and had audio reference quality headphones/audio sources/know what lifelike audio is like, you won't missed it...

Its not about QC, the products looks from the outside "perfect", QC can't filter it, they just quickly check the outside, listen if its sounding thats it. If it were not the finding from DIY poster re23071998 and my comparisment exposure, the 'unhappy' saboteur worker thought she/he couldn't be...

Actually it doesn't matter from which seller, because the first real one is from the same seller, just 2 weeks apart of ordering, because I was impressed by the first real one. Just read through the reviews of any sellers, unsatified customers got the fake ones, like this one review from other...

Edited pic from re23071998: --- I received today the 2nd pair JC10, ordered a week apart from same seller. As calculated expected this one is "fake" worth $3 ones from their cheapest, due their worker's sabotages. You can't missed it if you received the fake/sabotaged ones, its like night and...

First you got a defective/lemon pair as different type/material drivers gives imbalanced sound characteristics=rejected, can you post pic of the other driver?, because this transparant diaphragm looks like a common mylar/pet drivers with the common lackluster sound quality. Edit: I get it, only...

Don't bother, its not only about bio-cel, its the whole physics acoustic/design/form/size/material/resonance composition etc. Iem are flawed from origin, small driver, tunnel vision, claustrophobic sealed uncomfort pressurized sweat/material resonance influences etc.etc. Like I said EP05/JC10...

Maybe I didn't tell, they both aren'tBright sounding, more towards warm analog tube like. JC10 have copper and EP05 have silver plated copper, EP05 sounds because of some silver much more dynamicer/lifeliker perfect for everything, JC10 for easy relaxing. since I ordered a 99,9% silver cable...
