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
