I thought I would post my impression of the Dekoni Premium (platinum) Memory Foam pads with the T70p. 
 
To this date the Dekoni pads are the best.  The hybrids from Brainwavz are a close second, but the Dekoni's just "feel" better on the T70p.  The pads themselves fit better as they are designed for Beyers which also makes putting them on WAY easier.  It took me all of 5 seconds, compared to the near 10 minutes for the Brainwavz pads.  The memory foam is slightly denser on the Brainwavz, with a slower recovery time when pressed.  Having said that the Dekoni are more comfortable to me.  They seem to rest with lest pressure points, which I attribute top the fact that they are oval, not circular like Beyers are designed.  The Dekoni pads are about twice as thick as the stock pads so my ears no longer press near the drivers. This makes them far more comfortable.
Sonically the Dekoni create a better seal for my ears and in turn create a nice textured bass that is very lifelike.  I would say it increases the bass presence about 1-2 dB, which is the perfect amount.  Because the Dekoni pads (similar to Brainwavz) have a very thin fabric mesh inside the pad openings it helps tame the treble just even to reduce the harsh edge that can appear on some tracks.  These sonic findings are almost identical to the Brainwavz pads.
 
In summary, Dekoni > Brainwavz.  While they are very similar sonically, the Dekoni pads win in comfort and isolation.  I also think they just look better than the Brainwavz.  Honestly I wish Beyer used the Dekoni pads as the stock, I am sure it would have been a much larger success.

Did you get your Dekonis on Massdrop?    Mine were a b****h to fit.

Yeah I got them recently from Massdrop.  They were super easy to get on, took all of 3 seconds to put on. 

Here are what the pads look like on the T70p.  I think they look real sharp!

Just got a pair of these. What should I expect?

Always expect the worst. But hope for the best. Then you won't be disappointed. 
 
Initially you will most likely be very disappointed with the thin sound. If you are the patient type give them time and get used to them and you will discover what they truly have to offer.

I'm selling my pair if anyone's interested. Strangely enough it's not the treble that bothers me, but the dip around 3k that makes music sound kind of lifeless. Still, glad I gave them a shot. I also have some sealed spare pads I'm selling.

End-game earpads for T70.
 
Yaxi's for K240/K271 special edition earpads. I purchased these pads for my newly acquired AKG K240DF on ebay, and naturally I tried to put these on my T70s, always suffering for lack of bass despite super detailed highs. 
 
I tried beyer's EDT770, J$ lambskin, range of Brainwavz pads so far, I dare to say this is the best. these pads surprisingly increase the amount and punch on bass(due to plastic acoustic reflex plate inside the pad), keep sound uncongested, with more airy and wide soundstage, and super comfortable to wear as well.
If you interested in, I recommend to give these a try.

Yaxi pads are available outside Japan.

Those look super nice!  I know I have found the Dekoni premium pads work very well too.  They do a wonderful job at increase bass, but not reducing the nicely detailed treble.  Picture of them is above.

Just thought i would add my 2 cents worth on these headphones - reading through the thread and many of the unfavorable reviews of this headphone.
In my experience Beyerdynamic do not typically release headphones without doing a lot of development work- so the large variation in opinion is unusual for the brand and price with my impression being more people not liking than liking these.
 
When i got my pair they had been broken in and my first impression was as many have written in that they seemed a bit thin and lifeless - however this was running off a number of portable DAP's I have through a fiio E12 and cayin C5 portable amp
When I moved up to a desktop system utilising a beresford camian MK11 ,and a Burson Audio DA160 Dac as the sources from a dx90 as transport and then fed these sources through a Burson Soloist or an Eric MacChanson tube amp I had a completely different impression
 
I was immediately impressed with the level of non fatiguing detail these could produce and there was a good level of sub bass coming through as well- there was still the absence of lower mid bass but I found the sound addictive and i was finding i could listen to these for hours on end and could fully engage with the music
Switching back to a portable amp and DAP set up the sound reverted to a thin and lifeless feel that i did not enjoy - even though on other headphones these portable set ups were very good
It would seem that these headphones need a mid level or above system  to get them to sound as intended and you need to give them a chance to adjust from bass heavier headphones
 
As a reference i normally like a warmer or bass heavier sound - and have tried and sold many mid tier headphones but have kept and love my denon D600/mm400, sennheiser HD600, HD700 and ultrasone pro2900 and now these I can add to the keepers list and  I have Sold and replaced my AKG K612/712 and DT880 with this headphone. 
 
Its probably true that first impressions count - and if i had not known what to expect and given them some time to find a good synergy I would have returned them or sold them as well - as it is they get a regular work out now and I am enjoying them very much.

What's the weakness in the tuning of T70 (not p) and how could we mod it to improve those weakness?

Well the t70 and the t70p really have the same overall tuning, and would respond similarly to modification.  A very simple modification would be to change the pads.  I personally changed the pads to the Dekoni premium pads which improved the comfort, reduced treble sharpness, and gave the mid-bass a bit more presence.  In addition, because the pads are thicker than the stock pads my ears were further from the drivers.  This gave the sound a bit more air, although this did reduce the intimacy of the sound.

Is changing pads making the soundstage bigger?

Yeah it does, cause your ears are further from the drivers so it gives the feel of more space in the sound.
