Assertive sound – interpreted with slightly scooped mids and combined with clean detail transmission even in the highest frequency ranges – the Hörluchs 3-way in-ears. Three high-definition drivers deliver a perfect, spectacular sound. You can also select a more balanced sound set-up and enjoy balance on every acoustic layer. You can also choose punchy, high-precision, dry bass. Then you can select between a bass-heavy option and the ultimate bass boost. Our 3-way sound design gives you a soundscape to lose yourself in.

universal design

Hörluchs’ many years of experience in the medical field pays off for you. Our audiologists and sound designers have used our broad experience with the ear, hearing, and thousands of ear impressions, our extensive knowledge of acoustic behavior and the endless variation of the human ear canal to develop the perfect universal in-ear headphones for you. Our in-ears are designed to fit perfectly inside your ear, similar to a customized earmold. You will receive these headphones with matching earmolds called domes. These are made of smart memory foam or a soft silicone. Each available in three sizes, domes ensure your headphones fit securely and create a seal with your ear.

2-pin exchangeable cable

Our cables make no compromises when it comes to quality. This 2-pin cable is easy to exchange for making repairs; thanks to its excellent quality and rugged design, it is a popular choice among top stars and professionals in the music and entertainment industry. Please note that the 2-pin option was not designed for frequent cable replacements. In the “top” version selected here, you use the bending element included in the cable to guide it up and behind the outer ear. This provides a very secure hold and lets the cable disappear discreetly on your neck. With the 2-pin variation selected here, you can replace the cable with any other 2-pin cable from Hörluchs. We offer headset cables and a wireless option as well.
