Headband headphones comprise two earcups, which are connected by a band which runs across the head. The mechanics of the headband ensure that the earcups are pressed against the ears on both sides, to guarantee stability. Unlike earbuds and In-Ears they are characterised mainly by a better impression of space in their sound.
Open-back headband headphones, i.e. those with perforated earcups, excel in this regard, but because of a lack of isolation, are not suitable for portable use. For this purpose closed-back models are used, which also produce more powerful bass.
