The earphone that breathes quality in every detail!

First class DSP correction, high-finish chassi, tough cord and superb comfort - with the right price!

The EarPhone-12 is our first earphone ever!

As you could expect from XTZ, we went for something completely new.

The idea behind this project was not only to create a good earphone, maybe with an excellent price/quality ratio, but to build something revolutionary, something that expresses our passion for music and technology.

The limited mechanical space in an earphone makes it difficult to create a perfectly balanced sound over the whole frequency response.

The solution of the problem is advanced DSP technology. First - frequency response is measured in a dummy head, then it is carefully corrected with DSP technology. This combination leads to a perfect result without compromise.

Measuring dummy-head



Sound quality for the picky!

Don’t settle for half measures - we choose only the best DSP Technology that satisfied even BMW, Bentley and Rolls Royce.

Too good to be true? Well... see below!




Complete optimization

The advanced algorithm optimizes both, frequency response (amplitude) and also impulse response (time domain). Applying Dirac’s DSP optimization, the result is an impressively balanced and flawless sound, which can’t be described better than stunning, breathtaking.

Quiet and relaxing

We also paid a lot of attention to efficiently reduce influence of background noise. We obtained a very high attenuation of the noise floor, caused by rumors in the listening ambience, which contributes to a much cleaner and dynamic sound.
