What is Reddit's opinion of Hosa Phx-206Fbulk 6-Inch Adaptor PHX3F to XLR3F?

From 3.5 billion Reddit comments

I purchased some secondhand Henry Engineering gear in hopes of setting up monitoring and talkback for our podcasting studio. The ins/outs require what the manual calls "euroblock connectors".

I bought these: https://www.amazon.com/Hosa-PHX-206FBULK-6-Inch-Adaptor-PHX3F/dp/B003D83OWC

...but the terminal end is too big and the wrong shape. If I google "euroblock connector", that term seems to refer to all different kinds of connector. I've tried emailing Henry Engineering about this, but they haven't gotten back to me. Does anyone happen to know what kind of euroblock connectors these are so I can figure out what to order from mouser or digikey?

I was just gifted a cts600. I bought these to make the Xlr connections. http://www.amazon.com/Hosa-PHX-206FBULK-6-Inch-Adaptor-PHX3F/dp/B003D83OWC?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00
