Here are some of my fave custom headphones we’ve made this month
The latest in our range of ultra low capacitance cables is is this balanced cable for HD650, HD600 and HD580. This comes terminated in a 4pin XLR to plug into high end headphone amps but can be ordered with two 3 pins or anything else you need.
This one is roughly 0.17pF for a 1.5m cable and is super soft and flexible to make it possibly the ultimate audiophile cable for the HD650

For the past year we have been working on a range of audio cables with very low capacitance. In our listening tests getting the capacitance as low as possible seems to make a more noticeable improvement in sound than changing the conductor to silver or using other exotic materials in the construction. Our initial design got the capacitance right down to around 30pF which is considerably lower than just about any RCA cables and we got really good feedback from our customers. Our original design is made with teflon coated silver plated copper then used clever geometry to get the capacitance and inductance as low as possible. The one thing that was holding them back was that even though teflon is a great dielectric it does still build up a small charge adding to the capacitance.
After a bit of theorizing and a lot of trial and error our new one uses silk covered litz copper. The silk is not there because it sounds cool or has any magic properties.. It just creates a small air gap between the wire and the outer cover – this seems to help stop the wire acting like a capacitor and building a charge. It sounds exotic but does not cost any more than teflon SPC so we can keep the price the same and get better results.
I present our new Ultra low capacitance silk covered Litz cable… Including the connectors a 1m cable now has less than 4pF – BOOM
These were a bit of a personal project – I love the DT770 and the T1 and was wandering how the T70 fits into the lineup. So I ordered some in to have a bit of a play. As you would probably expect the T70 sounds better than the DT770 and not as good as the T1. Like the DT1350 the bass is a little recessed but very detailed – overall a nice pair of closed backed headphones.
After having a listen to them stock I decided to give them a touch of flair.
This pair has been given a custom colour shift emerald paint job with a vinyl lover stencil design. They have been re-cabled with out ultra low capacitance litz copper wire and re-wired internally to take a balanced connection. They have also got a detachable cable.
Since making a lot of toys to go with the balanced output on pono we are doing a lot more balanced conversions on beyerdynamic headphones. The theory is much the same for all the different models but it gets scarier as you go up the range due to the cost involved if something goes wrong – so far we have not lost a patient so I may give some T5p the same treatment soon
Here is another pair of balanced headphones for Pono Player. These are some beyer DT1350 which have been re-cabled with our low capacitance litz copper and re-wired internally to make them balanced. On the other end of the cable is a 4pin MiniXLR socket so you can plug in a choice of adapters to work with various other balanced and unbalanced configurations.
These ones have been airbrushed in british racing green and yellow to make them really stand out
Here we have another in our range of modified headphones designed to take advantage of hi-res audio and balanced output on the PONO Player. Keeping with our theme of taking already great headphones and making them better we have plumped for the HD650 ( we also the the same mods on the HD600 as well )
The HD650 have been very popular in the audiophile community for a long time and are now widely being used in studios as well. They are very comfortable for extended listening periods and have a lovely open airy sound. You can close your eyes and you feel like you are there listening live. The only real complaint most people have it that they sound a little veiled and maybe a bit too smooth. This is great for MP3s as they are quite forgiving of the digital artefacts but in the age of High resolution audio we thought they could probably produce a bit more detail and be made a bit more engaging with a few tweaks.
On this version we have removed the foam from the back of the driver which is a popular mod in the DIY community and really livens them up a bit. We then mass load and brace the driver using lead to help the low end detail.
We also swap the stock cable for one of our ultra low capacitance ones the improve timing and impact which again brings out the added detail of FLAC and high-res sources . We can supply an adapter so you can use the balanced pono cable with other equipment as well for a small extra cost
The lead adds mass which helps the driver reproduce the very low frequencies more accurately. We did a bit of testing using a similar mass of clay and the lead seemed to improve things more noticeably. We are still not 100% sure why the lead made additional improvements but it may be something to do with leads diamagnetic properties pushing some of the magnetic flux back in towards the voice coil – either way it livens up the HD650 and HD600 and gives more low end detail.
You can buy them now in our shop HERE
We made a bit of a schoolboy error and ordered a box of HD600 instead of HD650s. We need to shift them quickly so we can get some HD650s in so if anyone wants a pair of modified or customised HD600s just emailm me through the custom cans website.
We can do all the standard mods like mass loading the drivers, removing the foam to make them less veiled and re-cable them and I’m willing to do them at cost price to clear them quickly. Unfortunately our cost price is only just below retail so don’t expect amazing discounts but we can make you a pair that sound even better than the standard ones you can buy in the shops and we can personalize them if you want as well
Over the next week we will be introducing some balanced cables for the HD700 and HD800 to plug into the PONO player.
This first one is an entry level cable for the HD700 – I know what you may be thinking… why produce a basic and relatively inexpensive cable for connecting an expensive pair of headphones to a high end player?
Well this will enable you to run them in balanced mode and using the second amp in the pono will help it drive them better and louder. If you are not a “cable believer” and just want to get the advantages of a balanced connection without investing too much money then this is for you.
It will be available in lengths up to 2.5m and will cost just £25 if you want it “naked” or £30 wrapped in a colour of your choice from our shop HERE
We will of course be making some sexier and more advanced cables for both the HD700 and HD800 which will be ready to go early next week and I will try to remember to post some pics of those as well
We have been selling our modified version of the HD25-1 for a couple of years now. It has an SPC cable, modified drives and improved damping to give them incredible levels of detail across the range, better bass extension and less muddy bass. Now we have made a version to take advantage of the balanced mode on the PONO player – ideal for the audiophile on the go
