I finally settled on KOSS SB 49: (1) circumaural ear cups (large enough to sit on head, completely surrounding the ear and avoiding pressures of on-ear cups), well-padded; (2) wired connectors for headphone and for microphone, with sliding volume control on wire; (3) large padded head band, adjustable length; (4) position-adjustable microphone; (5) good sound quality (Skype; video conferencing; online videos; classical, blues, folk, international music); (6) cheap--$25 at newegg about a year ago.
