It fits snugly without pressure, stays in place even during movement, and remains comfortable for hours. It’s free from plasticizers, easy to clean with water, and available in a wide range of colors. Ideal for those who value comfort just as much as protection.
bachmaier® fidelity.
The wavebreaker for your ears!
You don’t just need quiet – you need clarity, control, and true sound. bachmaier® fidelity is designed for musicians, sound engineers, communication professionals, and anyone who depends on high-fidelity audio. Custom-made, linear in attenuation, and uncompromisingly precise – built for peak performance in the studio, on stage, or in demanding work environments.
Individual situations. Individual protection.
The filter technology in bachmaier® fidelity is designed for those who rely on true-to-life sound, speech clarity, and acoustic balance. Instead of simply blocking noise, the filters actively shape the sound – purely through physical principles, without any electronics. The result: smooth, linear attenuation across all frequencies. Highs, mids, and lows remain clear, direct, and natural. Four filter levels, color-coded and tactilely marked, adapt precisely to your sound environment. Just swap the filter – and hear it right.
Nice to know.

Your bachmaier® hearing protection is sweat-resistant and durable. To ensure a long lifespan, clean it regularly with a skin-friendly cleaning agent or a damp cloth.
