Enjoy playing in complete safety

Whether on stage or in the privacy of the studio, the decibel level around you is often very high, which can lead to noise-induced hearing loss (NIHL). ASTRO HYBRID custom monitors isolate you from this prolonged exposure, reducing ambient noise above 30dB, thus allowing you to control the input signal at safer levels. Noise from the stage, the public or peripheral sounds will be reduced, which will allow you to monitor at lower levels and fully secure hearing protection. With the Earprotech® ASTRO HYBRID, you can take advantage of the power of your amplifiers without any risk for you.

In-Ears ASTRO HYBRID, personal and robust

Just like your music or your way of playing, each ASTRO HYBRID In-Ear is totally unique and personal. ASTRO HYBRID by Earprotech® introduces a modular system consisting of an interior designed in acrylic material, effectively protecting the drivers, and an ultra-soft silicone exterior custom made using the latest 3D technology, thus fitting perfectly to your ear. In this way, you will enjoy resistant and comfortable monitors that will provide you with perfect insulation to protect your hearing.

The rhythm that runs through your veins

The ASTRO 4 HYBRID monitors incorporate 4 high-definition Balanced Armature drivers. This technology offers you the best fidelity and detail on the market. The ASTRO 4 HYBRID combines a driver for treble, a driver for midrange and a dual woofer for bass. Thanks to this dual woofer, you will be able to feel the full force of the bass and experience all the power you need when setting the pace. Additionally, the electrical signal it uses eliminates distortion and produces excellent audio clarity so you don't miss the slightest nuance of your sound. With the In-Ears ASTRO 4 HYBRID, the rhythm will no longer only flow through your veins.
