Compliments to the 'chef(s) involved in designing, tuning, and shaping the 'Dioko into a remarkable set of IEMs that have cooked up a new Statement Dish for IEMs and Planar IEMs.

They don' t have "Mickey D's" branding, but "I'm Lovin' 'Em"...

All hail Crin. I am impressed with Dioko. Haven't taken them out since they arrived 10 hours ago. I like them at least as much as my Kato or Timeless. They scale up to high-end amps really well !

I have nothing against Dioko iems. Nice product for the price. But I ordered them with upgrade cable. And the cable is a mess.
1. It’s a protruding 2-pin cable while iem have flat 2-pin connection. Mismatch.
2. It’s heavy and has a chemical smell.
3. The connection between swappable plugs and cable is flimsy. Disconnected few times in my pocket.

I'm lost for words about what $99 can get you nowadays. The accessories it came with were very nice, with plenty of ear-tips, a nice cable, and an awesome case. Went through my test playlist on all my equipment, and I could see why people would like this, then I decided to try it balanced (4.4) and like night into day it went up a notch in overall tuning. To the point, that I can't stop listening to this set.
Bass hits with perfect control, it's not as hard as the S12 but it's nicely controlled for my taste. It retains the detail that the Timeless has but has a better overall tone, and the spacing & imaging is just so spectacular. Instruments just come all out at you and with the spacing, simply wow! Cymbals have a wonderful tonality to them as do all the sounds to my ears. Vocals are slightly forward, intimate but never shouty or harsh. Treble has wonderful extension, I will say with the 3.5mm termination plug it had a touch more brightness to it, with the new 4.4mm cable it toned it down and smoothed everything out like a milky dream. I haven't tried another cable to see if it was that or if the fact of having just a little more juice made it better, but I have no intention at the moment as I'm really enjoying the music this brings to my ears. This is without a doubt my favorite planar driver IEM and the price is unbelievable for the tuning they accomplished. The only thing I can see being a problem is fit, I personally have no problems when I'm sitting or just moving from room to room, but going for a long walk/jog, it can wiggle out from the seal, but I have medium to small ears. As for comfort, I have no complaints, very comfortable and creates no soreness. Some songs I listen to, "Le Chat Noir" by Philippe Chretien, "I Would" by Kan Waken, "Crash" by Charly Antolini, "Evening Star" by Cannons, "Days Without You Remix" by Satori, "Icarus" by Synthetic Epiphany, "Momma Sed" by Puscifer, "Moving Mountains" by Anima!, "If You're On the Water" by The Saxaphones, "Why This, Why That and Why" by Jean-Michel Jarre, Yello, "Bungee Jump" by Captain Hook, Astrix, "bad guy" Billie Eilish, "Charlotte's Thong" by Connan Mockasin and lots and lots of MMD/Nightcore as well.
Equipment I really enjoyed listening with: Monolith Monoprice, SMSL SU-9(Crystal 2 setting) x iFi Zen Can (bass on) and on the Shanling M3X. I did try it on a host of others, including the FiiO K9 pro(AK) and it sounded good on everything.

Timeless plays one spectrum of my music library greatly, (EDM/MMD)
S12 plays the other spectrum of music I like awesomely, (Pop/Acoustic/Vocals/R&B/Jazz)
The Dioko plays both spectrums at almost the equivalent level, with good vocals.
Making them a very versatile IEM with a good, almost neutral tuning, and a slight bass bump.
Still evaluating the Hook, at first it was alright, but turning up the volume and listening to it, I’m beginning to open up to it, but still need more time with it to compare.
Re: Hook, Hook is superior, but it is also 2x as much.

Upon unboxing , immediately swapped out the default tips for dekoni mercury 4.9mm and ditched the cable for linsoul loops and went thru my regular tracks ranging from k-pop, j-pop, edm, rock. Coming from L9 i was on Lgain Vol42 to get my regular listening volume but for these boys had to set to Lgain Vol65 to get the same listening range however something felt off.. Everything felt neutral and was unimpressive so upped the gain Mgain and readjusted vol50, suddenly everything felt alive, going thru the same tracks again this time felt much better but still wasnt enough to impress. I swapped back to the default cable which was running a 3.5m and went thru the tubed amp(ultra linear) for n3pro and OH boy did it felt amazing suddenly, somehow or rather silver/gold composition from loops was thinning out the treble and mids too much. I left the player running for another hour+ just to let the tubes warm up and just let it run through my library whlist listening.
The most impressive this guy will shine in is in the mids(vocals, piano , guitar instrument will shine) , bass wise, running thru my diverse system albums. it did well in some tracks and ok for most. overall bass performances was acceptable(not muddy or overly bobbly) especially for high bpm tracks. planars drivers haha. Treble wise was ok(its nicely tuned, its enough to hear my background instruments but it wasn't enought for me) , purposely went thru some sibilance causing tracks, its safe to say i detected none.
Technically I was say its a safe bet if your library music got a great range of pop/rock tracks. Its a beautiful all rounder. Kudos to the 7hz team and Mr Crinacle for another round of success

The IEMs sound good, I find them quite analytical (not as much as the LZ A7s, but enough).
The packaging is truly premium, perhaps a little big.
They seem a bit hard to drive: I have to set the volume of my IFI Gryphon (balanced output) over 80 to get a medium-high volume, while with the 7Hz Timeless or the RAPTGO HOOK-X
I set the volume on average around 70-75).
The Tripowin balanced cable is functional; however the insertion mechanism of the various Jack adapters has an unstable stop.
For the price they have, they are very good.
