Re-Cabling the Grado GS1000 for balanced connection

Posted by JFunk on 11/05/2016 in Special projects |

We re-cable a lot of headphones and convert a lot to balanced so when someone asked if we could do a pair of GS1000 I confidently said yes – no problem. Having done quite a few pairs of entry level grados I thought it would be easy enough… I was wrong 😉
Like with all the other grados they are glued together with hot glue but the ear cup is a single piece so very tricky to get to the back of the driver. In the end I had to use a modified scalpel which I heated with a blow torch to safely remove the glue without heating the delicate driver or earcup. It took four or five hours of heating and picking before they finally popped out. Once the driver was out it was plain sailing and while I was in there I changed the grille to a more open mesh. The time taken was worth it though because they are a thing of beauty.

HD 25 headphone connection Mod

Posted by JFunk on 21/03/2016 in Uncategorized |

The Sennhesier HD 25 Headphones are legendary, having been around for over 25 years, they have been the headphone of choice for DJ’s and and recording professionals all round the world, and in all areas of the industry, this universal adoption has been down to there mix of fantastic audio quality/sound isolation, and there rugged reliability.

However this is not to say they we at custom cans do not see them back for repair from time to time, and as such we are always looking at mods and adjustment’s to improve the reliability of these fantastic headphones.

One of the most common issues we are being asked to fix is a loose or poor connection to the drivers, this tends to show as loosing audio in one ear, that can sometimes be fixed by wiggle of the cable, and is often caused by a bit of corrosion or dirt, between the connector and the spring in the socket that it connects to.

we have in the past produced a video on our you tube page showing how to cleanup and adjust these springs to try and improve these issues, but we have come up with a better solution.

As of today we have Replacement Gold Springs available to replace the stock ones that sennheiser supply as standard, the replacements will not corrode the same as the original ones, and as a side effect should also offer a better connection to the driver itself.

They will also fit the the HD600 and HD650 and all Sennheiser series of headphones that use the two pin spade connector.

Cool Retro Sony Headphones

Posted by JFunk on 19/09/2015 in Special projects |

We got sent this pair of classic Sony MDR-3 to re-terminate with a 3.5mm jack and to shorten the cable to make them more suitable for modern portable use.
Everyone here agreed they were the coolest headphones ever so I thought I would have to add them to the blog. They are beautifully made and the fact they still look this good is a testament to their build quality. I am super jealous of these and am tempted to hunt some down on ebay for my self

Custom Airbrushed Technics RP-DH1250

Posted by JFunk on 18/09/2015 in Pro DJ Headphones |

If you have flicked through this blog then you will know that we mainly specialise in sennheiser and beyerdynamic headphones but we have done a fare few pairs of technics headphones in the past. The RP-DH1250 are the updated version of the classic RP-DH1200 and some of the only Sony V700 style dj headphones still being made.
We had a request to make some look like the even older RP-DJ1200 in dark gray but with feelgood instead of technics where the logo went. As it is such a subtle design and the same font has been used, if you don’t look closely you would never guess they weren’t like that from the factory

Balanced HD800 cable with 4pin XLR

Posted by JFunk on 16/09/2015 in Technologys, Uncategorized |

With most of today’s high end headphone amps offering a balanced connection to squeeze a little more sound quality from high end headphones we have designed a range of balanced cables to get the most out of them.

They are made from our ultra low capacitance silk covered litz wire so have much lower capacitance then most high end cables and as they are hand made we can offer them in custom colours and lengths

Here is one of our balanced cables for the HD800
