@mngrif That cable looks good and the price is right.
Have you seen or shopped at Monoprice? Thye have high quality gear, tons of levels and fair prices.
Used and recommend them, even network cabling gear I got from there.

@mngrif Even found one exact replacement cable for mine, Sennheiser HD565 : https://www.amazon.com/NewFantasia-Replacement-Compatible-Sennheiser-Headphones/dp/B07WWNGYQ7
@mngrif Not cheap, but there are may choices. Seems to be the same cable as the HD6xx line, which is popular. Got to look in AliExpress, but my current cable is still working.
