T70 just has a felt pad behind the driver in the depth of the cup.  It is quite insufficient, as a few T90 users pointed out when comparing headphones and noticing how T70 has too much cup reverb/resonances versus T90.  Kind of a let down there on Beyer's part when they do better with DT770 and DT660 in terms of acoustic dampening.

Good to know, I figured they wouldn't swap over given a look at the pictures. Nothing a little hot glue wouldn't help with, still, my swap is done and they sound superb.

And a cable built to match...

I'd like to add a dt 770 (250 ohm) to my stable. Think a closed back would be especially nice for meets, where the ambient noise level is a bit high. Looking around, I see some have a "dynamic limiter to protect from hearing damage".

How can I be sure and avoid this "improvement"? Is it a special version or model? Don't want to get involved in buying and returning.

Thanks!

Never heard of that, have some links?

Let's google that: https://www.google.com/search?q=dt770+limiter&ie=utf-8&oe=utf-8
 
It seems that it can sometimes be distinguished by red (instead of black) headband end blocks.  It appears to be exclusive to Europe.  Can be had in 32-ohm, 80-ohm, or 250-ohm versions.  If it doesn't say that it has a limiter, then it is a regular DT770.

I see a couple without the red marker as limiters. These are a rarity for sure. It's for studio use when say you're listening to a drummer channel and the drummer hits the mic with his stick. No use on known material, great for instances like this.

Thanks folks, I'll make an effort to find a decent buy on a pair that has a detailed description, but not one word about limiter.

Just ordered the "Mass Loading & Damping Kit", I will post some results afterwards.
 
What is everyone's favorite pair of pads for their 770s? I have the HM5's on mine and really think I should have opted out for leather.

I found the mass loading and damping to be very worthwhile- it really tightened the sound up and fixed the flabbiness in the bass. Frankly, I can't find anything wrong with the stock velour pads.

There isn't anything wrong with the stock velours, but some folks may prefer the sound with some other pads.  Some guys love K702 pads around here.
 
I haven't given K702 pads a serious try, and I did try regular all-pleather HM5s but preferred the stock velours over those.  I've thought of trying out HM5 velours, but have been procrastinating on the idea.

I wouldn't suggest it, I cant understand the hype behind them to be honest ... /r/headphones thinks its the best thing since sliced bread.
 
Replacing my stock he400i pads with the angled pleather ones however was a game changer ...

 

[Zimtron]

Finally got around to installing the sound deadening and listening to a few tracks.

Bass is much more precise and way less 'boomy'. These are on par with my 400i's in terms of bass now.
 
Not bad for $20 after the exchange rate, you can do it yourself with any other sound deadening material however.

This is the kind of very effective mod which can only be carried out on a DIY basis (i.e. can't be offered in a commercial product), as it appears to involve lead!
