Yes that is one of the main reasons we focus on beyer and sennheiser - both companies sell all the parts separately. They are also really good at keeping parts of discontinued models - sennheiser still sell new parts for the HD414 from the late 60s

@@CustomCans That's insane. Mad respect for German thoroughness (except for the problematic bits)

@@sulgrave_ With problematic bits you probably mean the softtouch surfaces in the Golf IV?

@@NavySeal2k if only the Germans could come up with some kind of _solution_ that provided some _finality_ to your Golf IV problems.

@@sulgrave_ we sat together and decided the best outcome in the end would be to get rid of every last bit of soft touch surface ever in existence

Yes - they could teach Apple a few things

@@CustomCans Not only Apple there are huge amounts of companys in these industries that don't care at all about that sadly

If I remember correctly, the 1990 haver a notch in the ring that you attach the pad to - the trick is to hook the pad over that notch and then twist the pad and the notch will guide it into the groove

Yes they are ;)

we have a load of the sockets and connectors as we remove them when we convert them. Pop an email to custom cans and we can send you the parts for the cost of postage. The wires will all still be attached so a simple straight swap

@@CustomCans bless you guys. I'll be in touch!

Yes we have tried in the past but getting them manufactured was too much hassle. We may eventually get round to it

@@CustomCans since I’m in the United States can I buy some of those wire snap in connectors to make my own internal cabling without soldering direct? Thanks guys. Too bad you aren’t here as well.

My pleasure!

Yes - it does smooth out the 8K peak ever so slightly

@@CustomCans thought so. Cool. Does the new wiring do anything? Doubt it. Except to give you more sense of a robust headphone. The length is too small prob to make a diff Thanks and good work. Too bad I’m in the US and shipping is crazy now

Yes - you can re-use the headband cable and that should be pretty easy to figure out once you are in there so I thought I would show how to upgrade it as well just in case some people wanted to do that

This is quite an old video from before we got serious about videos .. we are gradually getting better at it and have black magic cinema cameras and lots of lenses but they are all primes so still no zoom but do try to use one camera for close ups.

Yes, I was surprised the first time I opened them up

Soz i’ve lost my marbles

LOLz ;) My editing is better now so my mum does not get any youtube time any more ;)

We fitted a passive filter to take out the 8K peak and made a few custom painted pairs

You should probably ask them... I know moon audio use to convert headphones so maybe they are modding the 1990s

I'm gonna do it, but they just sell the cable. Anyways beside this fact, if they sale a TTRS balanced cable that cable must have the 4 pins for the modded 1990, right? @@CustomCans

If they are out of warranty and you are in the UK you could send them in to us to take a look at

I think they are a 3 pin MOLEX Pico-Clasp connector but the pins are too small to take out FAT wire which is why we solder them directly to the driver

It may be a loose connection inside, The drivers have a wire that connects it to the mini xlr socket - you could try carefully unplugging it and re-inserting it and see if that improves things

@@CustomCans i found out what happened... the tiny tiny tiny copper wire on the driver pcb got lose but i confused it with a hair and ripped it out. Maybe it was fixable but now not anymore for sure. I doubt i can get a single new driver so i think i just buy 770 and never buy such fragile expensive things again. 😐

The damping material is bitumen based. The wire we use in the workshop is far too thick to work with the original connectors but we are designing a DIY kit that will plug in to them so people can mod them them selves without needing to solder. The connectors used are molex pico clasp

@@CustomCans Thank you for your message and for answering my questions! I'm looking forward to your DIY kit.

@@CustomCans : Any progress on that kit?

@@CustomCans Are you still planning on releasing the balanced wiring kit using stock connectors? I would be quite keen on giving it a go!

@@guiver7772 Sorry - we got over run with orders and have not been able to get the kits made - we are booked up until the end of Feb but will try to get them designed and made then

;)

No - I am not sure if they have it listed separately - you may have to contact them or ... We have a load of them we have taken off headphones. Pop custom cans an email and we can sort you out with one

I don't think it was a cost thing as it would not have cost much more and the DT177x was balanced and built on the same platform.

Yes we convert one of the standard cables to a 4 pin so you can use them with atandard single ended equipment. You will probably have to pay some import duties but you can also claim the VAT back once it leaves the UK so you get about 20% back. White with black splatter would cost £100

We sell them pre-modded with custom cables here customcans.co.uk/s/s/index.php/headphones/balancedheadphones/balanced-beyerdynamic-dt1990.html

You should be able to get one from beyerdynamic - they sell spares direct. It may be worth opening them up and unplug the wires and plug them back in again to make sure it is not just a lose connection. You could replace the headband cable like I did in this video but it is tricky to do a neat job

@@CustomCans i opened them up and the red wire solder on the mini xlr input was loose. I think im going to do the balanced mod already! Can you point me on the direction of where to buy the cable you used to go from left to right? Also the balanced xlr input thing

Our litz wire is around 1mm diameter - so 2 x 1mm wires and the paracord outer cover - that is about as thick as you can get through the original grommets. I don't think you probably need to go as thick as we do - it will be easier if you chose a slightly thinner wire

@@CustomCans Wow, that's thick. :-) Thanks for the info and the suggestion to use something thinner. I really appreciate your adice!

Pin1 L+ pin2 L- pin3 R+ and pin 4 R- The connectors normally have tiny numbers next to the pins or here is an image i found images.app.goo.gl/67yPGt9rQGn1dJYF7

@@CustomCans you’re an absolute legend man

@@CustomCans you’re an absolute legend man

Sorry I may have said negative when I meant positive - We normally use the pen mark on the driver as the positive side

Unfortunately we don't have any more stock and our next delivery is not due for a few weeks. When they arrive I will make some waterfall charts though

@@CustomCans thank you

@Danny At the moment on the 1990, the changes are very subtle, slightly more detail in the bass from the extra weight and slightly more open sounding as the dampiing is stopping as many reflections inside the cup. We are doing more indepth tweaking at the moment and may have a V2 version of the mods in a month or two - hopefully we will get the treble peak these have smoothed out a bit

We don't sell a kit at the moment, we solder directly to the driver but it is a bit too dangerous to sell as a DIY kit. We should have a DIY plug in kit in a few months though

@@CustomCansany update on this?

Yes, That is what we use

I am sure there will be someone in the land of the free but I don't personally know anyone

@@CustomCans I found someone in NY through Etsy and they're charging $100 for the conversion, however they do not offer the mass loading nor damping. In your expert opinion, are those necessary? Do they alter the sound signature of the headphones?

@@brianl839 No, the change is only very subtle on these so no real loss if you don't get it installed. We just do it while we are in there as it is pretty quick and easy to do

@@CustomCans thank you for all the help and advice brother, happy Sunday

We do work on other brands but we are a bit understaffed at the moment due to staff being on holiday so we are not taking in any mods until mid July

I mainly get to play with sennheiser and Beyer headphones - The HD25 and DT770 and DT990 all punch above their weight fro around £130 but it is worth checking out headphone forums for advice on other makes

@@CustomCans hi what about hd660s

Yes the 660 are very good but a bit over the 300 budget normally.

@@CustomCans What do you think about the shure srh 1540? Compared to these?

L+ L- R+ R-

@@CustomCans this is the correct order 1=L+ 2=L- 3=R+ 4=R- is it correct?

@@rockyjhon6736 Yes that is the pinout we use here

@@CustomCans thank you friend

You can buy them directly from beyerdynamic

you could do that but you would have to neaten up the headband wire holes which may end up being more work than doing it this way

@@CustomCansJust snip them inside and leave them?

@@NavySeal2k I just thought it would look odd with one in front of the headband and one behind rather than both at the back. It is probably a good DIY option of you want dual entry but not something we would do here. If you don't mind a single sided cable... as a dual 3 pin cable is not standard, you would need to make a custom cable, if you have the skills to do that you may as well just replace the 3 pin with a 4 pin and not have to worry about the headband cable issues. The way we do it, we replace the headband cable with a Litz one but you could just re-use the stock headband cable and you would then only need to replace the socket which would make it much easier and cheaper. I may do a "DIY" video to show how to do it the easy / cheap way just replacing the socket

@@CustomCans Ok, now I have a completely stripped 1990, but now is the question, is the positive or the negative side marked? o_O

Here is a video of another pair being built kzfaq.info/get/bejne/bqmibMeG1L-shY0.html

It is a bit tricky to measure as it is litz but it has 84 strands per core, each strand is 0.071mm in diameter

I think it depends a bit of what amp you have, a lot of amps find it easier to drive high impedance headphones like these in balanced mode. You also get better channel separation but if you have a decent amp already the difference would be subtle

@@CustomCans i currently have the ifi zen dac

@@jonathanleonard9507 The zen dac does put out more power in balanced mode so you should hear a small difference going balanced but probably not huge

@@CustomCans ahh got it! but will it be considered as an investment for future dac/amps that has balance outputs? Or it isnt worth it?

@@jonathanleonard9507 It is totally up to you ;) I have an RX8 which cost £2600 I then spent around £5000 on engine mods which probably only gained me around 10% more power - most people would say that it was not a wise investment but I really enjoyed the journey and knowing I squeezed everything I could out of what I had. It is all about how much it is worth to you. If you did it your self it would cost £15-£50 in parts depending on what your cable was like and maybe 4 hours of your life ( so whatever your hourly rate is in work X4 to factor in the value of your time ) . If you paid someone to do it then maybe £50 to £150 again depending on the balanced cable you get with it. If it is likely to give you £200 in pleasure then it is a bargain :) but if you are short on cash I would not bother - the difference is quite small

It lets you use them with a balanced amp - if you run them balanced you should get better channel separation and you normally get a bit more control over the driver but it would totally depend on what amp you use

If you search for car sound deadening you should find the damping material we use. We make the Litz wires here and at the moment we don't sell them separately so you would have to make your own

We make the litz cables here - they are made using litz wire of roughly 1mm outer diameter and covered in 550 paracord. If you search for sound deadening sheets for cars you should find the damping material we use

@@CustomCans thanks but i still don't understand what is the purpose of using litz cables does this improve the sound or is it for durability? Is that car material like an adhesive tape? thanks for your answers
