Actually I had the same reaction but it looks to be a 2.5mm trrs 4 pole to 3.5mm trrs 4 pole extender. I've never heard of using 3.5 mm jacks for balanced use before. I'd be worried about putting a 4 pole mic plug in there though and causing some chaos.
A year ago, I asked the seller on Amazon to custom make a few adapters for my 3.5mm balanced PM3 and Z7 cables. He then listed them for additional sales including this one.
It's made for 4-pole 3.5mm balanced, same as the balanced plugs used by Hifiman, GeekOut, iFi, and a few others.
Both ends have slightly different pinouts (since AK's 2.5mm is different) so the adapter is more than just an extension. It also properly converts each end.
