2.5mm to 3.5mm Cable?

So I need a cable to go from my Astro mix amp to my xbox one controller. I bought 1.5m xbox live chat cable from Astro. But it doesn’t work. Can someone give me a link to the cable I need please? Amazon say one isn’t available for the cable I was looking at.

I’m not sure what monoprice charges to ship to the UK but http://www.monoprice.com/Product?c_id=104&cp_id=10429&cs_id=1042909&p_id=7124&seq=1&format=2

One of the reviews on that item says

Then xbox doesn’t use a true 3.5mm jack which is hard to believe. I believe MS specs more than a random review.

There’s tons on ebay for cheap. Many with free shipping.

Actually chris, with the new controller coming out, there is a true 3.5mm audio jack.

I know there is. That is why I said I believe MS specs more than some random review saying it doesn’t work with the controller.

My bad. I didn’t understand your post. Lol.

I have the 2.5-3.5 adapter. I just need a cable, but I have no idea which one works for the Astros.
