Open versus closed headphones
But, critically, open headphones also let your music out. Even if you’re listening at a moderate volume, everyone in the room will hear a tinny, annoying version of your music. So open headphones are a poor choice for environments with people nearby, such as open offices, home use with anyone else in the room, airplanes, buses, or trains. (Don’t be that guy on the subway.)
Um review (até resumido pro padrão Marco Arment) sobre fones de ouvido.
O melhor é que lá, no metrô, quem incomoda é quem usa fone de ouvido que deixa um pouquinho do som escapar, mas eu trocaria os DJs de ônibus daqui pelos de lá a qualquer hora.
