An electroencephalography (EEG) headset can include an arrangement of straps that provides the ability to adjust the size and shape of the headset once disposed on a user's head. In some implementations, the headset can include a first elastic strap extending from a first side of the headset to a second side of the headset along a topside of the headset. The headset can also include a second strap including at least one inelastic portion and at least one elastic portion, at least one EEG electrode coupled to the second strap, a third elastic strap extending from the first side of the headset to the second side of the headset along an underside of the headset, and a plurality of connectors that couple the elastic first strap, the second strap, or the third elastic strap.
