<p>Headgear (10) having an adjustable mechanism (11) for placing an audio transducer (12, 14) in position relative to a user's ear. In one embodiment, overlying bands (38, 40) encircle a portion of the user's head to maintain the transducer (12, 14) at the desired position. The bands (38, 40) are adjustable and are releasably secured by a rotatable clamp (42, 44). In another embodiment, the overlying bands (236, 238) are coupled with a breathing mask (211) by a mounting clamp (250). The rotatable clamp (25) allows bands (236, 238) to be adjusted to place the transducer (222) at the proper position.</p> |
