With each pair crafted from a single piece of aluminium, Bang & Olufsen's H3 in-ear headphones are designed to complement your look while providing exceptional audio. The custom drivers are professionally tuned & work with an integrated bass port for greater low-end performance. & as a finishing touch, the H3s have been modelled to reflect the contours of the inner-ear for more comfort & a natural acoustic flow. Listen to what you want Custom built 10.8mm drivers bring you every part of your music's range with stunning clarity. Expertly tuned & covering a 20 Hz to 16k Hz range, you'll be free to explore every detail of a track. The headphones also feature a unique mini bass port in their construction that allows the lower end to come through with all its subtleties intact. Active Noise Cancelling is also on hand to electronically reduce the amount of outside noise which surrounds you. This makes for an even more immersive listening experience; one which you listen to what you want. Functional design The H3's unibody aluminium design makes these headphones tougher & less prone to vibration at all volumes. The volume can be adjusted via an inline microphone & remote which makes it simple to stay in touch, & in control, of your music while on the move. Comfortable fit & an ergonomic design emulates the structure of the ear for greater comfort & listening quality. With four different sized earbuds to choose from (extra small, small, medium & large), you'll be able to find a comfortable, secure fit.
