    Open Ear

    Open ear headphones are designed to sit close to the ear, barely touching it. This technology allows sound to be transmitted through the air to the ear without blocking ambient sound.


    Because they do not press against the ear, they are ideal for long-term use. They offer greater safety as they allow you to hear your surroundings (ideal for running or cycling outdoors). Additionally, the sound sensation is more open and natural, without the intense isolation offered by other types of headphones that close the ear canal.

    If you prefer to listen to music or calls without losing touch with your surroundings, open ear headphones are the perfect choice!
