I think you are right. I had one of those 2-pin adapters with the older QC15s but when I gave them to my nephew I didn’t keep it. Apparently the AA 15/25s need 3 pins, which include 1 for power. The i20s in-ear don’t have the old 15 (or new) 2-pin adapter [minus 1 for power from the AA proprietary version]. The 2-pin stereo adapter is pretty cheap ($7.95) so that’s not so bad. I may get one.
