Two Designs.
Your sound, your fit.
The bachmaier® fidelity is available in two carefully engineered designs – both developed to precisely integrate high-end filter technology while delivering exceptional wearing comfort. Choose the version that best fits your needs, your application, and your preferred handling.
Larger design – grippy and durable. Easy to insert and remove. Ideal for those who need maximum control when handling.
Compact design – discreet and comfortable. Sits in the ear canal, perfect for long wear and high sound quality demands.
Your material.

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.

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.
The linear filter technology provides smooth, even attenuation across the full frequency spectrum. No muffled highs, no distortion – just pure, accurate sound.
Whether you're in an interview, a conversation, or on duty: you hear and are heard – without having to remove your hearing protection. You stay connected – and reliably protected.
Each hearing protection is individually crafted from your ear impression. No slipping, no pressure – just a fit that feels made for you.
Choose from four linear filter levels – from light attenuation to strong protection. This lets you tailor your hearing protection precisely to your environment.
Simply wipe it clean with the cleaning cloth – your hearing protection stays ready to use. No water, no risk.
Choose from 13 colors and add your personal text – precisely engraved by laser.
fidelity isn’t a disposable product – high-quality materials, replaceable filters, and easy cleaning make it a reliable companion that’s good for you and the environment.
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.
Light linear attenuation for natural sound with moderate noise
position
Medium linear attenuation for clear sound at high noise levels
Strong linear attenuation for loud environments with a full sound spectrum
Maximum linear attenuation for extreme volume and ear closure
