Debating on the 4.4 or 3.5, pros/cons? Should i get an adapter, does that even exist?
Well that’s a great question.
People are having good luck with the Kimber cables however they fit into the system. I’m not a total expert on matching adapters with cables? There is basically 1/4 inch single ended and 4.4mm Pentaconn balanced cables supplied with the Z1R.
I suggested to/phronesis a 4.4mm balanced as he does not show any support equipment in his profile. It would be best to get the cable which goes with your equipment and stay away from adapters when possible.
The Sony ecosystem relates with 4.4mm fitting everything plus it’s balanced. So if you have a 4.4mm plug as an output it is the way to go. Then your also able to use the plug on home amps and with the Walkmans which support 4.4mm. Though there is nothing wrong if someone is using a 4 pin balanced and get the Kimber for the Z1R that works.
Also amazingly any other Sony headphones like the Z7 or Z7MK2 use the same cable as the Z1R as headphone inputs; so it’s a system.
If you have multiple headphones and multiple sources it saves you $.
There is 3.5mm balanced but you rarely see it used as well as the 2X 3.5mm balanced that came with the Sony Z7; which again is not used much.
The adapters which work easy are 2.5mm balanced to 3.5mm balanced and 2.5mm balanced to 4.4mm balanced. The issue is I don’t think there is any correct way to go balanced to single ended or single ended to balanced. And of course there are plenty of single ended 3.5mm to 1/4” around. But typically adapters are known to add a slight change in sound which you want to avoid.
Though you also want to think ahead, so if an adapter would work until you get more equipment in rare situations it could be the way to go; as it’s temporary.
