This is the cable for my Sennheiser headphones. does is have a particular name??? Mine isn’t working properly and I’ve been trying so hard to find a new one to buy but nothing comes up in my country with just searching for it. I don’t know what the thinner part is called.
All Sennheiser cables are the same which is a 2.5mm to 3.5mm headphone jack but they’ve a particular twist & turn proprietary hook that doesn’t allow third-party ones (which I found out the hard way) to enter the headphone side (2.5mm) without using theirs. The cables fray like Apple’s lightning cable and are of shit quality as well while priced a premium.
Not all of them have the twist and lock, I had a pair of pxc 550 that came with the 2.5 to 3.5 that didn’t have the locking groove and when I wanted to use that cable on a pair of HD450BT I had to cut into the cable to make it fit, another way to make a non proprietary cable fit is to snap the little nub that locks the cable in place
