Beyerdynamic Custom One Pro Thread

Has anyone replaced the stock cable with the vmoda mic cable? I'm looking to get the silver one to match my plates and wanted to make sure it would fit and do its job well

I'm actually using the Fiio replacement cable. The sound becomes slightly louder and soundstage slightly wider. Not a bad upgrade considering the price I bought the cable at only $59.(Singapore price). Definitely better than stock cable.

If you want a bunch of cheap replacement cables can always go for the nice 3.5mm cables that monoprice sells.  I sometimes use it with a coupler with the original cable as an extension.

To the admins: sorry for double posting but i've found the official thread for my headset right now!
 
Hi all mates!
 
I have a problem with my Beyerdynamic Custom One Pro i've buyed on Amazon.
The first couple produced a strange vibration (barely audible) in the left earcup while listening to certain songs in certain "moments" of the song.
I decided to replace them, same problem on the same side!
 
What is the matter?
The source?
A whole faulty lot?
 
For example, when I listen to this song:
 
https://www.youtube.com/watch?v=AkFqg5wAuFk
 
At the third repetition of the main riff (around 0:02 to 0:03) I hear a strange noise, no matter the source, if is my original CD or my smartphone, my desktop PC, I clearly ear a strange vibration in the left earcup at that time range of the song.
And this is the second headphone replaced.
Obviously, no problems with other cheaper headphones or some stupid stress test from 20 Hz to 20 kHz, i'm going crazy!
Some owner of these headphones encountered the same problem?
Or maybe I'm too picky ... Or these headphones still require a good break-in?
Sorry for my English, thank you for your time and for any future responses!

Actually I came here with the exact same problem. Slight buzzing in the left earcup, mostly when listening to bass-heavy songs, but also when pausing a song in foobar.

Also coming here with the same issue. Slight buzzing in the left ear in bass heavy music. Quite saddening considering I've only had my pair a year and half.
 
BUT, I also come here with a crazy, but possibly awesome idea.
 
Get this. Swapping DT770 250 Ohm drivers into the custom one pro body.
 
As of now it is just that, a crazy idea. But it does seem plausible as the drivers look very similar and are indeed very similar in size. the COP have a 50MM driver, whereas the DT770 has a 45MM, although this isn't my biggest concern. I'm wondering if the sound signature will be totally trashed due to the change of housing. Although they are both closed back (sort of), I'm afraid the sound would be off. I am a complete and total noob when it comes to these things, and the COP are my first true pair of "high end" headphones, although I do have fairly reasonable "handy" skills and can solder at least half decently, so no issues there.
 
I am aware that the cost side of things isn't worth it, but I love my COP, they fit me perfectly and mine are still in perfectly good condition and I see no use in buying an entire different pair of headphones just because of a driver issue.
 
This is my first time posting on head-fi , so I could be in a completely dead and useless thread as I'm not too great at searching the forums.
 
If there's already a thread/post on this subject, or a mods thread, feel free to direct me there because as said previously, my searching skills on the forums aren't that fantastic.
 
TL:DR - I want to swap DT770 drivers into my Custom One Pro shell. Any advice would be greatly appreciated as I don't want to shell out $100 for drivers and end up with a worse sound than before.

I've actually done this with my COPs and a pair of DT770 250s I had laying around. In addition, I added a half-circle of 1/8" thick self-adhesive felt in each cup and, as odd as it sounds, put 2 layers of paper towel between the black padding and the driver. It's considerably tamed the somewhat harsh sibilance and, to me, it feels like it's brought the dip in the mids up quite a bit.
 
My advice is to not apply too much heat when soldering everything back in. Did a little too much on one and had the terminal literally fall out. Luckily, with the COPs, that one's not used since there's a little board with solder points inside, but the damage is done.

Both of these are great and straight forward, too! You might even take a look at http://www.head-fi.org/t/172825/beyerdynamic-dt880-re-cable-guide-in-progress as it gives a more detailed view of the terminals on a Beyer driver.

Lists of mods and accessories that I have added to my 3 pairs (I only own 1 right now, the other were presents to my cousin and my sister) of COPs:
 
- The Beyerdynamic COP Headset Gear Custom One Pro Microphone
- Black Lamb Leather Audeze Angled Earpads
- Beyerdynamic Real Leather HS800 Aviator Headbands (both black and brown)
- Custom Cut 1mm Thick Real Carbon Fiber Covers
- Painting And Then Glossy Acrylic Coating All Of The Removable Plastic Accents
- Beyerdynamic DT 770 600 Ohm Drivers
 
Although the 600 ohm DT 770's drivers do have less base than the 15 ohm COP's drivers, they do gain a lot of base in return when you wear them with the leather audeze earpads instead of their stock velour ones and when you have the base ports set to position 3. Overall, all of the parts and components for these mods (including a used pair of COPs) cost me around $400 each (~$1200 for all 3 headphones) to make, and what I got out of it was what I can argue to be the greatest and most comfortable pairs (for the price) of audiophile grade headsets I dare say in our current time. I've had these headsets (paired up with their respective customized mayflower O2 + ODAC combos) for over the better half of the year (although the idea itself was conceived before Black Friday of 2014), and they've held up pretty well and I (and my cousin and sister) have had no issues with them whatsoever.

Here's some pictures comparing the original COP drivers with the 600 ohm DT 770 ones:

As far as I know these are also the only 600 ohm impedance closed-backed headsets (complete, not with separate things like modmic) in existence. And the 600 ohm DT 770s were the only 600 ohm impedance closed-backed headphones ever manufactured, although they are now discontinued.
