The headsets I used with IAL abroad (1.75 oz inc plug) had a light, springy headband at the end of which were two small, oblong, foam-backed "boxes", which sat on one's temples. The boom mic was fixed to one with a ball-joint and there were similar ball-joints for the "earpieces". These were amazingly good - like two tiny funnels which could be adjusted to be over, but not touching, the ear. So the only pressure was from the two foam-lined bits, which were virtually undetectable in use. I don't know who made them, but I've never seen anything which is anywhere near as good.
