Very supple. TNP IR Emitter wire feels high-quality (very supple)

Another guy says ". My one criticism is that the wires (conductors) were very, very thin. I had to cut the jack from the end in order to get the cable connected to my Niles unit. It turned out that I had to strip about 1" from each lead, then folder it over a few times (+ & - conductors) in order make a secure connection at the Niles. "

Never worked with THHN, have you? The stuff comes off the spool like a coil spring and stays that way. I always used MTW for control panels and I would call that supple. You can run it through wire trough without losing your mind trying to keep it from springing out.

Yah, THHN is basically nylon coated copper pubic hair. You gotta feed it from the spool directly into the EMT.
