Recabling a Pair of Beyerdynamic DT880 Headphones

Beyerdynamic is a family-owned audio equipment manufacturer based in Germany that produces headphones, microphones and wireless audio systems. The headphones produced by Beyer are very solidly made, I'd imagine the rugged designs have the travelling DJ in mind. Still, the sound produced by Beyerdynamics top-tier headphones is something the discerning audiophile can really appreciate. The DT770, DT880 and DT990 models are ideal choices for the listener on a budget, and if one likes what they hear, there are pricier Tesla-based models that Beyer has recently introduced, namely the T-1, T-5p, and T-70.

The Beyer DT770, DT880 and DT990
The differences between the 770, 880 and 990 are surprisingly not subtle. The DT880 tends to be the most chosen for neutral listening, it is a semi-open design and has the most well-balanced presentation of the three headphones. The DT770 and DT990 are much more bassy, with the heaviest bass response coming from the closed DT770. The fully-open DT990 seems to have slightly less bass and a wider soundstage than the 770. I personally think that the 770 is the ideal movie and gaming headphone, the 880 is the best for analytical listening, and the 990 is good for audio enthusiasts who need a fun-to-listen-to headphone that matches a typical speaker system's bass response. 

While the sound of each headphone varies, the process of recabling them is nearly identical. Aside from the driver and cup design, the headphones appear to be identical inside and out. For this post, I will be recabling the Beyerdynamic DT880 headphones. Below is a stock DT880.

The Beyerdynamic DT880 Headphone

The wire for recabling a Beyer and still keeping the single-entry look takes a little bit more care than a typical headphone cable. When braiding, the wire should go from a litz braid to two twisted pairs about 2 and a half feet from the end. One of these pairs is nearly trimmed off, only leaving enough wire to get to the driver within the cup. The other twisted pair will be run through the headband.

The wire is then sleeved and the long twisted pair gets some heatshrink to distinguish each side.

Then a four pin Neutrik connector is attached for balanced operation. If you are interested in reading more about 4 pin balanced connectors, please check out my post creating a 4 pin to TRS adapter cable

Cable terminated with a Neutrik 4 Pin XLR

Now that the cable is ready, the first step to getting inside the headphones is to remove the velour pads. These pads stretch over the frame of the cup, so there are no screws to remove, etc. You will notice a number of perforations on the inside of the pads, these holes make a big difference in the sound, covering them adds unwanted reverberation. If one replaces the velour pads with leather, it is preferable (in my humble opinion) to get the leather pads with the perforations inside. 

DT880 pads removed from the cups

The next piece is removed using a typical envelope opener to pry the plastic ring out of the cups. The plastic ring retains the driver and driver surround. Once it has been removed, one has access to the driver terminals. 

DT880 driver and driver terminals

There is generally a marking on the driver to determine the positive side. In this case it is a yellowish gold mark. I take the time to use a multimeter and verify this is the case before snipping off the stock wires. The left driver has three terminals, the center is the right signal which is not electrically connected to the driver but the wire that runs across the headband is connected to this terminal. The ground is also run from the ground of the left driver to the right driver. This is all removed and ignored as dedicated wires will be run directly to the drivers in the recable. This will remove unnecessary solder joints in the signal path and isolate the ground for balanced operation. Below is a photo of the shell of the DT880 stripped and ready for the recable.

The latest models of the 770, 880 and 990 have a square opening that the stock wire is fed into, This square hole needs to be dremelled out so that it is round, then heatshrink built up on the new cable for a perfect fit. A custom retaining system is set in place to keep the cable from being tugged out of the cup. 

Wires soldered to the DT880 driver

The wire is soldered to the driver terminals with the assistance of engineer helping hands. The wire is then fed through the little grommet to the other cup. The headband is now placed over the wire and sealed back up using the zip-lock bag type mechanism.

The second driver is soldered on the same way, and we have a complete headphone!

This headphone also has a balanced to single ended adapter so it can be used with both types of amps. 

Another angle
I hope you enjoyed reading this post. If you'd like your Beyerdynamic headphones (or any other headphones) by an experienced recabler with some excellent sounding cable, contact Zynsonix. Since the 770, 880 and 990 are all quite similar on the inside, each can be modded / recabled the same way. Here's a Beyerdynamic DT990 PRO with a recable with both a standard mini and a Pono output to maximize utility out on the road.

  1. Hi,

    I think you may have made a slight mistake in the introduction. The DT880s are semi open, while the DT990 are completely open.

    May I know if it is possible to improve the soundstage and imaging of the DT880 by removing the white thing between the driver and the aluminium housing?

    I have the DT880 but I find that the soundstage is rather narrow and lacks depth. It fails to project the sound in front and around me. In fact, it is worse in this respect than the much cheaper Audio Technica AD700. Perhaps I should have gotten the completely open DT990 instead and live with the recessed trebles.

    To those considering the DT880/990, don't get the 32ohm version. The 250 and 600 are much better sounding according to many reviews. Some even say that the 600 is much better because the base is more well controlled and the music sound more alive. I personally can't comment on this because I have the 250ohm version. Sort of regretted my purchase to be honest...

  2. Good catch, the post has been revised to reflect the correct info.

    I actually received someone's DT880s for recable that did not have the white plastic and felt housing around one of the drivers. I requested one from Beyer and replaced it, but the differences between the piece on and off were hard to distinguish. Perhaps with a bit more time and testing the differences would have been more apparent.

    The 600ohm version is indeed the most well rounded to these ears. You can always purchase the drivers from Beyer separately if you have the desire to "upgrade".

  3. Hi highflying,

    I'm the anonymous person who wrote the first comment.

    I guess I have to live with the less than satisfactory soundstage of the DT880 then... It simply does not give a 3D sound that the AD700 is capable of. The DT880's soundstage is quite a bit narrower and sounds more "in-your head" - it does not envelope me. As a result, it fails to make the music "come alive" and is not "involving" in any sense of the word. What a pity; I would have considered the DT880 a perfect headphone for me if not for this issue.

    Is it too much to ask for a headphone which has the same great soundstage as the AD700, but with the excellent frequency response of the Beyers? Do I really have to buy a Beyerdynamic tesla T1 or Audio technica W5000?

    I ought to mention that I'm not using terribly low end equipment. I have a TubeMagic D1 DAC.

    PS: Thanks for the quick response!

  4. Back when I owned a DT880 I didn't really have a problem with the soundstage. I remember it being wider than Grados and the Sennheiser HD600 / 650 headphones. You may try taking your DT880s with you to a meet to try them with some other amp / DAC combos before you give up on them. If they still don't do anything for you, you might want to save your sheckles for a pair of AKG K1000s, they are widely known as the king of soundstage ;)

  5. Can you reuse the original cable to convert to balanced?

  6. Unfortunately not, there are only three conductors in the stock cables.

  7. What wire gauge do you typically use for headphone re-cables? I'm thinking about re-cabling my 250ohm DT770's and was also wondering what wire manufacturer you recommend to match with those?

  8. I typically find that 24 gauge is the most ideal compromise between size and flexibility. I have used other gauges in particular circumstances, as low as 19.

  9. With reference from the diagram DT880 driver and driver terminals - Can I use
    a silver cable to connect at the driver terminals for one drive unit and still use original cable for the other side drive unit. If so how do I connect them ?

  10. Yes, you certainly could, however it's not very difficult to run the wire through the headband and I would recommend that for the sake of the sound quality. Otherwise you will end up with one driver with a solid connection, and one with X number of feet of silver wire, then the solder terminal on the first driver, then thinner enameled copper wire for another two or so feet before it reaches the other driver. Your ears may pick up on that disparity.

  11. Buenas tardes. Soy de Brasil, y estoy en duda en cuanto a los modelos DT770 DT880 Pro y Pro. Quals estos es lo mejor para una producción musical de estudio? Gracias

  12. I believe you're asking the difference between the standard and the pro models of the Beyers. The only difference that I am aware of is the clamping force of the headband, so you get more isolation from the pro models as they clamp a little harder.

  13. Hello, just came across your post and I want to thank you for the detailed description - it's a work I'd like to do with my old DT990 250 Ohm upgraded with new 600 Ohm drivers. I have a question, would the balanced effect be affected by the fact that the final connections will have different lengths to the left and right driver? If you make the Litz braided portion 1,5 meters until the left earcup, then you will have few centimeters to connect the left driver while the right driver will need 40-50 cm more. I assume this difference will not affect balancing in any audible way. Thanks, best regards, Marco

  14. Glad you are finding it useful. You are correct the wire length is different between the two channels and if you have really good ears you *may* be able to pick up a difference. If this is a concern, I recommend switching to dual entry, and drilling a hole in the bottom of the other cup. Coupling this with mini XLR jacks in the bottom of each cup makes a nice removable mod. It's just like here: http://www.diyaudioblog.com/2015/05/beyerdynamic-balanced-removable-4-pin.html but on both sides.

  15. Thanks for the prompt response! Well I have not such good and educated ears... so in these times of lockdown because of the COVID-19, I will search for the best connector I can sort out. I have some spare Lemo style small
    connectors 4 pins around the house, will probably stick with the "normal" configuration across the headband. Thanks again for suggestions and examples. Marco

  16. Hi. Great posts here. I just bought the Beyerdynamic/massDrop DT177x GO. It comes with a cable 1/4"TRS to a 4-pin mini XLR. I also just bought a Monolith by Monoprice THX AAA 887 Balanced Headphone Amplifier, which has a 4pin XLR balanced output. Although a studio owner, I new to higher end headphones and running tem balanced. Are these headphones w/o cable desgned to be run balanced ? and if so why can't I find a simple replacement cable that goes from 4-pin XLR to a single 4-pin mini-XLR for sale anywhere? Seems like a straight forward wiring job. Please advise.

  17. Hi rdt, yes, Beyerdynamic finally wired their headphones for balanced via 4 pin XLR, it was a very long time coming. You can't find the cable because it's a relatively niche market for something like that. I'm happy to build you one at zynsonix.com

  18. HiGHFLYiN9, thank you for this informative post. I have a pair of DT 880 Pro's that are having balance issues (right side is louder than the left), do you think a re-cabling might help? or would this be more associated with a faulty driver? Sorry if it's not too relevant, anything could help. Thanks

  19. Hi Jack, sorry to hear about the difficulties. If you are using a tube amp, try rotating the tubes, an expired tube can cause volume issues in a channel. If not, try turning the potentiometer back and forth several times to see if that might be an issue. Also try applying pressure to the connector back and forth using your hand to see if there might be a bad connection. If none of these reveal anything, it could be a failing connection or a failing driver.
