Yes, Fairphone wrote me on Instagram and by emial weeks ago: they were discontinued dueto other fairer and more sustainable project. Cable will be available again for 2 years untill out of stock.

Also I wrote and email to Support Unit. Here the replies:
“The modular earphones are indeed no longer included in our product portfolio but we are investigating alternative options. As yet there is no timeline or further details available.”
“We have to cover the warranty period, so we keep enough stock for at least 2 years after the last one was sold.
How long they will remain in our website however depends on how fast they sell until we reached the stock volume that lasts for only warranty support.”
"No it was not a limit edition, we are just looking for a more performant and sustainable product "
