The NTH-100 headband is fully adjustable. The FitLok™ locking system allows you to firmly secure the earcups in place so they don’t slip down and feel exactly the same every time you put them on. This also reduces movement when the headphones aren’t in use, reducing mechanical wear and tear and increasing longevity.
To unlock the headband to reposition the earcups, twist the locking tab above the earcups. After adjusting them to a comfortable position, twist back to lock.
