  OK.  Let me get this out of the way...I AM A BELIEVER!  The Amazon box was on my desk when I got to my office this morning.  No time at work for a quick listen so I plugged them into my iPod, stretched them over the box, and let them play all day on shuffle.  At the whistl,e packed them into the sweet case and chucked them into my bag for the drive home.  Back on the iPod during dinner...and time for the nightly walk of the dog.  Status...about 10 hours burn in and a good stretch to the headband.
 
Out the door, and I immediately go to my standby track for new phones, "One Word" on Birds of Fire by Mahavishnu Orchestra.  (Gear = iPod Classic 160G 7G > Fiio L9 LOD > JDS C5 > 90's)
 
SQ: I am duly impressed.  I should say upfront that I usually use the bass boost function on the C5 so I had it on for first listen.  The opening snare salvo is crisp and clean.  The bass is at the bottom of my skull...freakin' thumpin' solid.  The bass solo...perfect...moving right to the front of the mix, and just as clean and crisp as the snares.  McLaughlin on the right, Goodman's viloin on the left, Hammer's keys in the center and up near the top of my head...but still clearly separated from the bass.  All the while, Cobham's drums are floating from left to right to center and back again.  Separation is the best I have experienced on any of my phones.  For closed phones the sound stage is very good.
 
Comfort: No problem.  Getting them into the proper position on the ears is a bit tricky at first but once you find it...oh so sweet.  Stretching the headband over the box all day may have helped as I found the clamping pressure just right.  I had them on for about an hour during my walk with no discomfort.  Isolation seems to be good enough, but perhaps not quite good enough for air travel.
 
Last words:  I will be getting the Radio Shack cable tomorrow.  Don't need the remote with the C5 and I do not want anything at all getting in the way of that "oh so sweet" sound.  Second pair from Newegg ordered yesterday for $69-$20 rebate...already at my regional PO, should be delivered by Thursday...will be doing the bass mod to see if I can forgo the bass boost on the C5.
 
Keep the hype alive.

CHOO!!  CHOO!!  The Mikros 90 HYPE TRAIN is still on the platform.
 
ALL ABOARD!

  People HAVE to buy this headphone!
 
I am revisiting my beatles collection at the moment, and I never knew...that You Can't Do That had silent beatles oohing in the lightest way possible! :D
 
Well, I would have probably heard it on the re700s, but this headphone is awesome at its current price point, and does it better regardless.
 
GET THESE NOW! Only 59.99 with rebate, order now! 
 
It has amazing 3d imagery, pretty good bass quantity, despite not being BIG bass in stock, or unamped. Getting my friend to get the beats cable from me, and the amp is already with me, just need to borrow his ipod! :) Not to mention, the beautiful layering of the highs, mids, and lows! The hilarious thing is, some songs put it in that order for me, especially in the height portion of the soundstage. Pretty wide too, to be honest!
 
Thanks to pataburd, lorspeaker, and sf for this hilarious thread!

Vienbo,
Mod them, my friend, then "pretty good" will be expunged from your Mikros 90 HYPE lexicon and replaced with "gargantuan". 
The bass will plow you under.

Pataburd,
 
Help me like this headphone. The hype is warranted for the SQ at the price, but there are several major issues with this headphone that requires modification to enjoy.
 
- Which post# / bass mod should I use to keep the neutral signature, but enhance bass levels?
 
- Which pads should i use? The stock ones are awful, and I need to readjust the headphone every 5 minutes or else the sound changes. Extremely annoying.
 
- Best cheap cable? The stock cable introduces some funky resistance to enhance the low end in the sound signature, but it also kills detail retrieval compared to any standard 3.5mm OFC cable.
 
- These are portable headphones, but they are practically useless off a smartphone amp. My work iPhone barely drives them fully, and my Nexus 5 does not have enough gain to do so. They are extremely uncomfortable for properly amped long home listening sessions as well. 
 
If these issues can be fixed with mods, I'll be keeping these, otherwise they fall into the same issues I had with the M200. Excellent SQ, but extremely uncomfortable and not enjoyable.

  I went down the rabbit hole!!!
 
Did a "stop-gap" MikrosHypedBass Mod last night.  Removed the "bass port blockers" and tucked a 1.875 inch diameter disc of 0.875 inch thick open cell foam into the bottoms of each cup beneath the drivers.
 
BASSSSSSS???  Did Maxx and Lors mention the BASSSSSSS???
 
Want to go back in with doe skin, felt and some BlueTac to properly finish the job [tweak the "Smack" factor], but opening up that Rabbit Hole unleashes THE MOST POTENT, DEEP and CONTROLLED BASSSSSSS I have ever heard from a set of headphones.  Indeed the MHB knocks out the D7000 inside of a minute of the first round: the Denons cannot go this LOW, remain this FULL and stay this CLEAN.*
 
. . . 8! . . . 9! . . . 10! . . . and YER OUT!!!
 
 
*I compared the MHB with the stock 'phones.  But it is too early to say if upper and middle frequency resolution--at gossamer levels--is affected because I modded a brand spanking new set.  So break-in will definitely play a factor as I study the effects of the MHB Mod.  I will concur with Maxx and Lors that the mids seem more open and deep.  Vocals are fuller and better rounded/sculpted in space.  The sense of space overall is enlarged significantly.  Doing the mod is like letting the Mikros 90 breathe.  
 
This takes nothing away from the stock sound of these fine headphones.  But on R&R, I preferred the modded, unbroken-in MHB to the 400+ hours stock Mikros 90.  I must have listened to Fleetwood Mac's "Behind the Mask" four times just to make sure my ears were actually registering what I thought I was hearing.  
  

 
Pataburd...u have been ambushed !!! u actually went in there NAKED, innocent, with open cell foam , and not expect to be smacked left to right ..up n down...hohohoho.
Now that u let the beast out, have fun TAMING it...go turn over your drawers and see what u have to smack down the boombox.
 
( my mods are basic teasers for the unsuspecting....the advance mod is being put thru its pace...i have to use calipers n the final touch will be lazer inscripted patterns
tp confuse the standing waves.)

Well, I'll say this post officially cemented my decision to buy a third pair and mod them. You've prolly been hyping the stock 90s (minus cables) more than anybody, so this is good news; not to say that Maxx and Lors weren't already well on their way to convincing me. 
 
 
- Which pads should i use? The stock ones are awful, and I need to readjust the headphone every 5 minutes or else the sound changes. Extremely annoying.

 
I find this problem that so many people seem to be having interesting. I would've though the significant clamping force of the 90s would have eliminated movement. I mean, when I use them they don't seem to move at all.

Honestly, if the pads are still bothering you after stretching them out, you'll most likely need new pads. So, with that being said, to somewhat answer your question, the beats solo pads fit, but are a very tight fit and so far have been prone to popping off; however, the comfort overall improved with them. Ultimately, I haven't gotten much time to differences because of the aforementioned issues though. I do think Lors posted a pic of him putting the Alpha pads on the 90s as well. Other than that, pataburd or someone else will need to chime in.

As it is...the sound u are hearing are all from ABOVE the driver...the hole in the centre has been sealed off. 
The bass u are hearing i believe is from the interaction with the pads.
From my limited experience in modding, i find the mids n highs are basically preserved..
just the added dimension of the extra bass from the cup is added when the hole is unsealed...
the character of which depends on how/ how much damping u execute, to your taste.
The mods can be seen in the post on my signature (see below)
Each mod's sonic character is described briefly based on pairing with ipad n sansa clip+ , on  stockcable.
 
I am back to using the stockpads...u just need to stretch the headband to loosen it..
i try to bend it nearer the centre..instead of nearer the cups...in case it breaks :p
And i try to balance the cups on my ear, putting it further back, cos my ears stood out slightly.:p
Otherwise the cups will turn...
 
i have a pair of K518pads incoming...amidst the snow. Not sure how tight is the fit..but the dimensions look promising.

Didnt FIT...slightly too big. :p

If you don't tilt or adjust the pads to a very small sweet spot, the entire sound changes. The slightest movement leaves the sweet spot, despite the clamping force, making it a huge pain in the ass for consistent listening. Any semblance of bass goes out the window when that happens. This is why the pads and bass mod are highly desired... to increase the sweet spot.

Hmmm? Once I adjust to the "sweet spot" it doesn't move. Agreed, however, you have to adjust to the right spot to hear the headphone's full potential. And changing that cable makes a difference. Still doesn't beat the On1 in my opinion, but it may be a little ahead of the M500 (which is a great headphone but a bit top-heavy for me).

A while ago, i took a jewel screwdriver with me, and a 1/4inch square felt...
sat at Mcdonalds.... laid out the paper napkin neatly infront of me,
took out the mikros...
modded the left cup within a minute...
and two minutes tops on the right cup...weeeeeee!!!!
My lucky day, all the screws fell into place almost without a hitch..:p

Geez...listening to Jascha Helfetz on my audiogd amp,
my latest experimental mod, it's as if he is standing infront sawing away in his swansong concert.

Yeah, I've only had mine on 2 hours of burn in, and it's pretty much a given that I'll be a belieber as well :)
 
Yup, that track is pretty intense with the 90's. Listened to it via HifimeDIY sabre dac and C&C BH amp. And they have already also passed my Yes "Close to the edge" test (C3/BH combo) with flying colors - thoroughly enjoyed it. Porcupine Tree on the go now :)
 
 
Comfort seems fine for me without having done any bending. But I haven't had them on for extended periods yet, so we will see. But I like how they stay put (that's my biggest gripe about the M500's). Funny, I have no problem getting them to fit well to get good sound. Maybe I don't have a proper fit and they are sounding this good without it lol.
 
I also really like how light they are, and I love the compact case. I don't mind the thinness of the stock cable, and it sounds fine to me so far (although I will be looking out for missing details as bhazard is alluding to). I still have the Beats cable to try.
 
 
Indeed!

How many hours of burn in did you give the mikros

Well, eric pretty much said what I had to say: once positioned I don't notice any detectable movement.
 
I do know that you've posted a lot about fit issues, so maybe the small size of your ear opening/canal is detecting very minor shifts that we don't notice, or the shape of your ears promote movement even though the 90s clamp pretty hard. Either way, hopefully you figure out a solution that works for you.

If these issues can be fixed with mods, I'll be keeping these, otherwise they fall into the same issues I had with the M200. Excellent SQ, but extremely uncomfortable and not enjoyable. 

(1)  Ask the MODDster, Lors about the "Gentleman's" mod, using a patch of leather and BlueTac.  Go to Lors' signature and click on his link to Post 1089. 
(2)  Ask Maxx, Lors, et al for pad options.  I use and enjoy the stock pads without issue.
(3)  My favorite affordable after-market cables are the $24 (4ft) Pipeline ET-4 and the $15 (3ft) Auvio, both at Radio Shack, if not available online.
(4)  At home I feed the Mikros 90 all my top gear (which costs more than both our cars put together).  However, I still enjoy the MLs straight off my laptop, recognizing the limitations.  I do know that the MLs will extract what is best (and what is worst) from whatever gear I match them with.
 
Ultimately, if comfort is the deal-breaker for you, well . . . that's just the way it is.  For me the huge sonic rewards outweigh the comparatively small physical discomforts.   
 
Keep us posted.

  But I like my sonys...
 
and I like my audio technica im-02s...
 
And more importantly, those m200s!!!
 
But since, according to some, believe that the teac does beat the m200s, I will be able to sell some iems. The only headphone I can sell are the re's since the es700s are heavily scratched, and the a900x has a chip on its metal housings, so no good deals there.
 
Or other peoples can wait!

vienbo is up on THREE COUNTS OF MUTINY!!!!!!
 
String 'im to the yardarm, Boys!
