3 corresponding drivers (instead of just 1-2) deliver a particularly detailed sound image. Hardly any other earphones in this price range reproduce the enormous sonic richness of high-resolution music so well. This is made possible by the patented hybrid driver structure. A balanced armature driver controls the high and mid frequencies. A third - dynamic - driver mainly emphasises the bass. Together they create an extremely precise listening experience with dynamic power and clarity. Elegant metal design. Optimum wearing comfort. The H1770 has a piezo ceramic driver, which is exclusively responsible for the upper frequencies up to 40kHz. Furthermore, there is a dynamic driver with a diameter of 40mm and an additional bass reflex driver - which also looks like a classic dynamic driver and is designed to work on the same principle as a loudspeaker. The headphones are small, light and foldable, so they can be stowed in the supplied case (with mouldings for the folded headphones!) for travelling. Advanced drivers. The H1707's high frequencies of up to 40kHz are achieved through the use of piezo-ceramic drivers. The piezo-ceramic driver is combined with 40mm metal chassis from aerospace technology and fast, powerful bass reflex boxes as in classic loudspeakers. The triple driver technology of the H1707 also delivers distortion-free sound. Luca Bignardi, one of the most renowned sound engineers, has carefully developed the technology of these earphones to ensure that they reproduce your favourite music as faithfully as possible. Comfort and high-quality workmanship: The headband and solid ear pads are not only robust and made of high-quality materials, but also offer you maximum comfort. The H1707 can be worn safely.
