Where can I buy a 4,4mm jack?

I’ve made an unfortunate mistake of getting a headset with a 4,4mm jack. I spent a lot of time and eventually found the one on the left side of the pic and… it doesn’t fit. The original cable on the right (it’s broken) has a neck I circled that the one I bought doesn’t have. As a result it doesn’t go all the way in. I’ve been searching the internet for about 2h now and I can’t find anything. Does anyone know a place I could get such a cable, where one end is 4,4mm jack and the other end splits into 2x 3,5mm? If it helps, the headset is from audiotechnica.
