In-ear headphones are inserted directly into the ear canal. The resulting pressure chamber effect allows for a powerful sound experience without having to turn the music up too loud. This is gentle on your ears and at the same time extends the battery life of your playback device. In-ear headphones also have excellent noise cancelling properties - so you're much less aware of distracting ambient noise. Thanks to their compact size, they can be easily stowed in any trouser pocket, making them the ideal companion when you're on the move.
