Thanks for letting me know. I will give our server guys a poak and see if I can get that fixed. We are insanely busy at the moment but trying to wade through the torrent of emails. If you don't get any luck with jfunk@jfunk.org you can try info@customcans.co.uk The jfunk.org server is on...

I don't know if you have already eMailed us about it but we have just had more stock delivered so if you pop us an email with your order number, we can investigate and potentially send out a replacement if it is properly lost in the system

I am glad you like the cable and thanks for the feedback. I will try to find a way to make the seam a bit softer. As for Brexit... Yes it is crazy that we can ship things to all kinds of places like Afghanistan and Botswana with no problems but it is really hard to get stuff from the UK to...

It takes a little while for things to get to europe at the moment but if you are concerned, DM me with your order number and I can check on it for you

I think the slight marks and wrinkles on the diaphragm / traces seems pretty normal. I have not noticed chips on magnets but, looking at it, the chips must have happened before they were assembled or the magnet chips would be stuck to the magnets. Personally, I would not bother returning them, I...

"After the headphone tour I noticed that the paint was worn out in some spots on the headphone so there will be need of better way to paint them." I have had good results with lechler megamack to protect paintwork. So some kind of automotive clearcoat may give themsome extra protection

Yes.. We had similar issues finding nice connectors for them. I think we tried something similar to the ones in your picture, they did not fit as standard, we had to shave down the corners with a blade to make them fit. In the past we used the cards hd600 ones and bent the top part with a heat...

Yes. It does have a small extension to fit through most cases

I have done a second video and tried to compare them to a couple of other headphones and taken a look at the frequency plot for them. I am still not great at describing sound signatures but gave it a go any way ;)

Sorry - the emails have got a bit out of hand over the last month or so and we may have missed it. Pop me a PM with your email address and I will look for it and get back to you

Yes, sorry - January is our busiest month and we have been a bit over run with orders and emails - we are working through the queue as fast as we can and have extra staff helping out. If you PM me your order number I can check where your cable is in the process

Yes - we actually have 3 pairs in today to be converted ;)

If you google miniDSP EARS. You should find it

I just made a video showing how to convert these to balanced, it shows how to disassemble them if you need to change any parts - may be handy for some of you Next month we are planning on some more in-depth mods and will try to flatten out the trebel peak on them.

on the 990 pro we add mass to the back of the driver which improves bass response and remove the white insert inside the earcup to make them fully open - that balances out the slight bass increase you get from the mass loading and makes them sound more open and airy. We can make a balanced pair...

It depends on the amplifier design. There are definitely some balanced headphone amplifier designs where bridging the negative on the left and right may cause damage but as the post above mentioned, as you have been running it for this long, your amp may be OK with it As a general rule of thumb...

We normally mark the left with black shrink tubing but you can request other colours They are designed not to be microphonic - the cable has a bit of stretch to it which allows it to soak up the vibrations more than most straight cables Our technician is still working from home so I am not...

Well.. It is a bit embarrassing, It is supposed to be gold for right and rhodium for left but we have 2 cable technicians and I just found out one was making them the other way. I would recommend using the video in the link below to double check

Oyaide make cables for the HD25 that are about 1.2 Meters and they fit the groove in the headband properly. Or you could just cut down a standard HD25 cable and re-jack it

COVID-19 Update. We are currently all fit and well and doing everything possible to stay that way - we don't normally get out much any way so no real change there ;) We are all set up with workstations at home so we can still continue making products in the event of a lockdown and also have...

They also have mass loading and damping mods as well as being re-wired inside and out with our litz wire to squeeze a little more out of them even when used in single ended mode ;)

Those look a little different from the ones we use but if you scroll down on the link below you can see how the bottom section unscrews, but the ones you have may be different. If you can't the them open then, yes, use a multimeter to figure out which pin attaches to which wire and splice yours...

The stock sennheiser straight cable is rather unusual as the conductor / wire is made from steel so they have incredible tensile strenght but it does mean they also have quite high impedance - the stock steel cable is around 4ohms where as something like the Oyaide will be around 0.5ohms so...

If you want something tough, I would go with one used on Pro DJ headphones ( not beats ) as they are normally designed to put with a lot of abuse. V-Mode make a nice cable with kevlar reinforcement for a sensible price. You can find it on their website. Or just re-use the old beyer cable and...

If you look at the drivers they each have a pen mark denoting which side the + connection is. So for your 3 wire conversion you will need both the positive connections and then join both the negative connections together. So.. you could solder 2 wired to the sleeve, if you are using a jack...
