Headphones deliver audio directly to the ears through cushioned cups connected by an arched headband. The headband includes sliding sections that permit resizing to suit various head shapes. Typically, these slides are positioned midway, ensuring the headphones sit securely without excess pressure.
A shift occurs when the slides reach their farthest outward setting to fit the broadest head circumference.
In this extended configuration, the ear cups stand at their widest apart distance. The headband maintains contact and stability across the head, channeling sound effectively to both ears. Movement of the head does not dislodge the fit, as the structure holds firm.
The slides lock at the end of their path, supporting normal listening with the headband fully deployed.
Here, the system functions at the boundary of its adjustment range, preserving operation with reduced capacity for additional expansion.
