Beyer DT770 Pro/ 80 Detachable cable MOD

I bought these headphones about a month ago and they've been great. I paired them with a Fiio E6 portable amp, and that has been my portable set up since. I've been keeping them in a Slappa hardshell case that fits the headphones alone pretty well, but trying to fit that 10 ft. cable in there is just a PAIN! So...I finally got up the courage to take them apart and install a 3.5mm jack in them. I got 2 jacks (one was a spare) from radio shack for a couple bucks, some 62/36/2 solder and I already had the soldering iron. I had to use a Dremel rotary tool to file down the place on the inside of the can where I would be mounting the jack so it would fit. If I did this again to the same headphones, I would get a jack that was a little slimmer and round, instead of the square one you can see in the pictures. I had some 3M foam pad things that were sicky on one side to fill the little bit of a gap on both sides of the jack so there wouldnt be more ventilation in one can than the other.

Maybe everyone will think I'm cool because it looks like I have Beats! TROLLOLOL

It should be so much easier to carry these things around now. I used to have the cable wrapped up and twist tied in a ball right before the amp, this is going to be so much more clean looking. Hope these pics help someone get the courage to do this to their DT770's!

It was actually REALLY easy. There's a ton of room to solder the new wires onto the driver after cutting the old ones off. It didn't take very long either. If you want to do this to yours, just let me know and I can take some more close up pictures of the soldering points and where I mounted mine.

a lot of people open up the cans and put dynomat on the back of the cup, or some kind of dampening material. I guess it tightens the bass a lot, I don't know if it does anything for the mids though. 

Beautiful ! I wish the premiums weren't discontinued! They look great, especially with the mod.

They open up so easily. The driver can be pulled right out after removing the circular locking mechanism and padding right behind the ear cushions. 

Here are some close ups

Take the cushion off and pry off the circular locking mechanism..

remove the thin black padding to reveal the driver :D

the driver SHOULD just pull up and out pretty easily. Mine came out with very little effort. (Sh*t, I just realized I'm taking apart the wrong can! Failololol)

Ok, this is the correct can now, all opened up.

The plastic ring and foam pop off. There isn't anything holding them on that you have to undo, just pull.

Close up of my solders. 

more....

jack shot....

and my case :) I got it at http://www.slappa.com/HardBody-PRO-Full-Size-Headphone-case?whence=

My headphones, cord, Fiio E6 amp fit in there with plenty of room to spare. (but not too much)

and all my work stuff...haha Badge, gum, USB charging cable for the E6.

All zipped up without smashing or forcing anything to stay in!
