This sonic signature focuses on the bass range for a spectacular, intensive and emotional dynamic experience. Bass sets the tone here, without suppressing clear highs and mid-range sounds. Whether it's R&B, hip hop or electronic, the beats dominate here. Bass driver performance is boosted, allowing you to perceive force without it being dominant. Do you play bass, are you a DJ, do you love your beat maker, or do you love to let it all hang out on the drums? Then this could be the sound signature where you feel most at home.


Our top performer: Hörluchs 4-way driver technology. The 4-way in-ears offer four high-definition drivers to bring top performance to your ear canals, exactly where you want it. Do you love delicate, bright, and precise sound? Then our HiFi sound design can create a true-to-life, extremely high resolution sound with the finest resolution in the mid and treble range. Are you a more chill, balanced person? Then choose our balanced set-up for your in-ears. If you love a booming, bass-heavy sound, you can choose between our discreet bassy or our ultimate bass-boost sound design.

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.
