Could someone please elaborate more on the "defective" part of DT1350s?
 
I picked up a pair recently, serial number: 12039
 
Is this a hit or miss thing or below a certain serial where these are defective.

As far as I know there is no serial number range for defective unit. Just use your DT1350 and enjoy them. If they don't sound good you'll know right away.

Just make sure you get a good fit and voila!

I'm still interested in the differences sonically between the two (I've searched here and google with little info). Just wondered if the defective ones really do sound that different?

There isn't a specific batch or range of serial numbers that are defective. Previous comments were based on bad QC from another Beyer model and is based on driver matching. Do they sound that different? It would differ between each set since how closely the drivers are matched is the issue being discussed. One set might be way off, while another might be only slightly. The only thing you can do is try to test with tones and sweeps to see if you hear a difference. 
 
The difference between early serial numbers and newer ones that people refer to is in regards to damping inside the cup. That can be searched for in this thread for more details, but again that is not in regards to a defect.

Yes it seems like it's probably something that varies with different degrees of mismatch, and not a have it/don't have it defect.  The only reason to even think about it is if you don't like what you're hearing.  It could be why.  But you could also just not like the DT1350 in general.  So if you don't like them, you might try another pair.  But otherwise I think you should just enjoy them and don't think about it. 
 
And again, it's not easy to hear channel imbalances or at least to identify them as such.

Channel mismatches are something I can usually zero in right away. I've had a few IEMs go down the toilet for such issues. As well with tubes. Immediately the imaging is "off center" and validation with my SPL meter have proven my ears correct almost every time. I've done a few frequency scans with my pair of DT1350s and ears/SPL meter and they're pretty tight L and R.

I did the sine sweep test and it seemed pretty close from what I could tell, though I was just earing it. I'm kind OCD about that stuff but glad mine aren't flawed at least from a balance perspective (seem spot on). They are great backup and travel headphones.

I've had a chance to sample 3 different 1350s. From my limited sample/experience.
 
Defective pair = inaccurate timbre + bloated mid-bass. Upper mids sound even more "uneven/odd" than correct pair. I think the dead giveaway is the timbre.
 
My 2 cents.

I have a slight feeling (and I could totally be wrong) but I think the placement / seal of each side is very important. I found that out the hard way a few days ago, kind of why I was asking. Once I get both sides sealed up good they do sounds pretty great, they're MUCH better then the other small headphones I have for traveling (B&W P5, Bose QC3 I was gifted, AIAIAI's - really just a bass drum headphone). I am kind of curious to try out the new Senns Amperior's (silver ones look awesome).

Getting the right seal in each side is indeed very important! If you are not able to find that position then you might as well forget about the DT-1350 (and T50p for that matter).

You might consider giving it a week or two in finding the right seal. The "break-in" of the earpads seems to have a factor too.

I found that too. They soften quiet a bit after some use and then they are great headphones.

I struggled with fit first week or so.  The "Hum" test works well - hum, and when you have the headphones in the right spot, your hum sounds loudest to you.  I can now just about nail the fit even time when I slip them on.  I might have to fiddle just a little, and I find pushing on the pads lightly while i do so helps get the seal and correct position seated in quickly.  They are not a difficult fit for me any more.  I still can't get more than a couple hours out of them at a sitting, though.

can someone show a photo of 1350s without the pads, is the driver exposed? I wanna know what it looks like but I don't wanna remove the ear cushions on mine yet, lol. Or can someone just tell me if I will damage the driver if I press the center of the headphones with the cushion, on PX100 you won't because the driver is covered with plastic. You know what I mean sorry for bad grammar thanks!

The driver is not exposed. Don't worry you can not destroy the driver if removing the ear pads is all you do.
