You can use an adapter -- they have ones that are a plug only, and there are some that have a short wire attached between the parts. They're exactly the same and I use both, it just depends on how much flexibility I need and the fact that the plug only ones can be fairly long. If it's going in my pocket, I tend to use a flexible one. I have bought them from Amazon and Ali, Fiio even makes a nice one.Hello everyone! Sorry if this has been asked before (couldn't find it using search function).
I have the Senn HD660s which have the balanced cable terminated to 4.4mm.
In what way can I connect them to the 2.5mm balanced port? Through an adapter? And if so which one?
Is there perhaps a cable that I can use instead of the Sennheiser one?
You can certainly switch over to a 2.5mm balanced cable, but I wouldn't recommend swapping cables back and forth. It's much better and a lot less wear on the plugs if you just use an adapter. I have moved over to mostly 4.4mm cables to match with my R5, and I have a bunch of adapters (including the one that came from HiBy). I also have several to adapt to a 3.5mm unbalanced for my gear that uses that.
