Brass design for reduced vibration, clear and secure sound:
Enjoy every sound more clearly and with less unwanted vibrations. The brass casing of our headphones minimizes distortion and the wide brass tubes greatly stabilize the sound. The new curved ear cushion shape fits securely in the ear, making it barely noticeable when worn.

Small but powerful membrane:
Hear every note perfectly clear with the compact, highly sensitive diaphragm.

Wide frequency transmission:
Enjoy deep bass and soaring highs in the expanded sound range.
The brass casing of the headphones resonates less than casings made of more traditional materials, resulting in a clearer sound in the mid and high ranges and a softer sound in the low frequency range.

Clear and stable sound:
For greater stability and clearer treble, it includes expanded copper tubes with an inner diameter 15% larger than conventional headphones.

Precise performance:
From hard rock to nightclub hits to pop classics, all music is heard clearly and powerfully, and every detail remains precisely discernible.

Timing control:
It uses special vents designed to optimize low frequencies and accurately reproduce deep bass rhythms and beats.

12 mm neodymium membrane:
For high sensitivity and low distortion levels, the small but powerful diaphragm has the same size speaker dome as a 16 mm diaphragm.

Particularly high sensitivity:
Sensitivity measures how efficiently an electrical signal is converted into sound. With these high-sensitivity headphones, you can turn up the volume without sacrificing clarity.

Comfortable listening to music:
An important aspect of its design was that it fit exactly in the ear, enabling several hours of comfortable listening to music.

Curved profile:
Thanks to its small size, the diaphragm fits neatly against the back of the ear, providing a particularly comfortable fit and better sound isolation.

Hybrid silicone ear tips:
The hard silicone design makes it durable, and the outer cover made of softer silicone is for comfort. Fits securely in the ear in four ear cushion sizes.

Smartphone-friendly and highly portable design:
Weighing around 9g, these headphones with included straps are also a great travel companion. Get rid of tangles with the serrated cable, which also has a slider for easy cable length adjustment. You can make your calls hands-free with the remote control built into the cable.
