I recently bought a pair of Sennheiser HD 598 headphones and a Little Dot Mk.III headphone amp/pre-amp.  The problem I have is the stock 10ft. cable not being long enough for where I have this set up for listening.   I called Sennheiser and they said they don't make a longer cable for the 598's - although, one of their techies said there are rumors that they may come out with a 20ft. cable just in time for the holidays. My next thought was to buy a set of plugs from them and make up my own 20ft. cable... only problem is that Sennheiser does NOT sell any of their plugs from their parts department.   To make matters worse, their techie said the locking mechanism on the (2.5mm) headphone side of their cable is a proprietary design and is unavailable from anywhere else.

Sennheiser's solution was to just buy an after-market extension cable and connect it to the 1/4" end of the stock cable, which sounds like a less than desirable alternative to me.

Suggestions???

Thanks!

Came to mind solder the long cable inside the phone.
A this long headphone cord may work as antenna if cable not shielded, but it looks to be a pro monitoring app, so sound quality not apply.

If you decide to try an extension cable, Grado has one.

FWIW, I'm using this headphone set-up for late night listening at home so I don't bother anybody else - so sound quality DOES apply!

Phones are very sensible to the cord in use, its are a no xover/filter loudspeaker in a near field use, for this manufactures use a very thin wire with very low resistance.

A shortest cord is always better so, a long cable may lack some quality of a short cable.
How much quality is hard to say;

Unfortunately, no.     The plug on the headphone side of the Sennheiser HD 598's I have is 2.5mm with a proprietary locking mechanism on the barrel that keeps the cable from falling out of the headphones.  As I mentioned before, Sennheiser will NOT sell their plugs as separate parts.

This no good.
Do Sennheiser will no sell it even to replacement to a Sennheiser phone owner??
I wonder how after market cable manufacturers as Kimber, Cardas etc  get the HD800 connectors to made its cables??

Moon Audio sells the Sennheiser HD800 connectors last time I checked.  Maybe they have the others, also.
