And how long do you think it will take till it is 'mature'?

Thanks all

Everyone has their own opinions on burn in but for me I played pink noise in them and played them at a high listening volume most of the time. I start out with just a normal listening volume at first until they burn in for about 24 hours (that's just me though). I noticed the biggest change happen after 48-50hrs. The mids were more present and the bass was tighter and sounded better to me. Later that went away again after more burn in. About 50 more (100 total) hours in I noticed a huge change again making the bass less muddy and the mids were more noticeable again (this changed again after more burn in). Changes were noticeable to me up to about 250 hours and I stopped burning them in after 300 but they probably are still slightly changing. 50 hours and 100 hours are the places I noticed significant changes that ended up changing again after more burn in.

Hey guys,

Pro 900 with E12 is simply MASSIVE.

I am in the market for these (as far as I can judge) brilliant headphones, and have found them at Amazon

for a reasonable price (unfortunately not the Lightning Deal).

 

But the one offered there, seems to be (or are) the old versions of this product.

 

From Ultrasone I got confirmed:

 

- Old Version: til May 2010 – 2 pcs. of 3 m cables (straight / coiled) and silver and black ear pads, adapter.

- Current Version: from June 2010 on – 1 pcs. of 1,5 m straight cable + 3 m coiled cable – 2 pairs of black ear pads, no adapter, with soft lack painting.

 

Also, when comparing more specs, there are some (important?) differences:

 

Old model:

Frequency range: 8-35.000 Hz 

Sound pressure level: 94 dB 

 

New model:

Frequency range: 6-42.000Hz

Sound pressure level: 96 dB

 

Also I am not sure if both offer S-Logic Natural Surround Sound Plus, or if the old model "only" offers S-Logic PLUS technology.

 

As far as I can judge, all these differences can make a significant difference between the two versions.

 

Question: Are all the "rave reviews" given at this forum based upon the old or new version?

 

Question: Has anybody tried both versions, and if so, were there differences? (taken burn-in into account)

Question: Is the "Kees Mod" applied on the old or new version?

 * Any other useful comment is much appreciated *

 

 

P.S. I have tried the new model already and liked their sound (although I don't know the burn-in time of these).

 

 

Txs in advance

 

I also would like to know an answer to this. I really want to buy this tomorrow on Amazon using my points, but they listed the older model. Is it possible the info simply outdated and they're actually selling the newer model?

===========================

EDIT

Based on one of the reviews, I believe they're selling the new one:

Hi Guys,

After using my PRO-900 for 120 hrs with fiio e11 AMP , the left phone stopped working. It works some times and stops then if i shake it or hit it with finger it sometimes  starts again.

Anybody have any idea what is going on ?

Same thing happened last time i replaced them then, now they out of 30 day warranty so i have to get manufacturer warranty.

Anybody used the manufacturer warranty in US ? what is the procedure ?

Let me know, Thanks in advance.

Can anybody walk me through the fitting of the Sony MDR-XB700 pads to the pro 900's i just picked up a faulty pair of the sonys and want to use the pads on my pro's
