a second portion overlapping the first portion between the first end and the second end, the second portion adjustable relative to the first portion; and
the counterbalance is connected to one of:
the first portion between the first end and the second end, or
the second portion.
7 . The head-mountable electronic device of claim 6 , wherein:
a length of the first portion is adjustable; and
a length of the second portion is adjustable.
8 . The head-mountable electronic device of claim 1 , wherein the counterbalance is slidably connected to the first securement band.
9 . The head-mountable electronic device of claim 8 , wherein the adjustment mechanism comprises a piston, wherein the counterbalance is adjustably connected to the first securement band via the piston.
10 . A wearable electronic device, comprising:
a display unit; and
a securement assembly, comprising:
a first band having a first end secured to the display unit and a second end secured to the display unit;
a second band connected to the first band at a first pivot between the first end and the second end and at a second pivot between the first pivot and the second end;
a first counterbalance adjustably secured to the first band between the first pivot and the second pivot;
a second counterbalance adjustably secured to the first band between the first pivot and the second pivot; and
an actuator configured to adjust a first distance between the first counterbalance and the first pivot;
wherein:
the display unit is disposed opposite at least one of the first pivot or the second pivot from at least one of the first counterbalance or the second counterbalance.
11 . The wearable electronic device of claim 10 , wherein:
the display unit comprises a display screen; and
the first counterbalance comprises a battery electrically coupled to the display screen.
12 . The wearable electronic device of claim 10 , wherein:
the actuator is further configured to adjust a second distance between the second counterbalance and the second pivot.
13 . The wearable electronic device of claim 12 , further comprising a controller electrically coupled to the actuator and configured to cause the actuator to adjust the first distance and the second distance based on a change in a length of the first band.
14 . The wearable electronic device of claim 10 , wherein the first counterbalance and the second counterbalance are manually adjustable.
15 . A head-mountable display device, comprising:
a display unit;
a counterbalance;
a securement band extending between the display unit and the counterbalance;
an overhead band coupled to the securement band to define a pivot between the display unit and the counterbalance; and
an adjustment mechanism disposed between the counterbalance and the pivot,
wherein:
