I have Hifiman 4XXs with the 2.5mm cable ends. As i already have other headphones with 3.5mm cables (balanced,nicer wire, and 4.4mm penticon), i need some cable tip adapters that will fit the 4XX’s. They need to be 3.5MM in and 2.5mm out. i see some Didi cables but i can’t even guess that they will fit the slightly recessed openings on my Hifiman(men?).
Can someone recommend ones that will fit for sure. I would rather not end up with several trial runs trying to get the right ones.
