Adapter 6.3 mm jack to 3.5 mm jack, gold
Just the right connection
Adapter KLB 6,3S / KL 3,5 gold
Way better than a simple straight (and long) adapter. It helps protecting the audio output jack from eventual breaking.
I bought a cheap one on ann on-line anuct site and the female 6.25 socket was a loose fit with the headphone jack and didn’t connect reliably, so I sent it back. I bought this one and it is a good tight connection with the headphone jack. Problem solved! Moral: you get what you pay for!
