bachmaier® fidelity is the sound solution among customized hearing protection systems – developed for all those who do not want to compromise on sound quality. Whether in music production, live performances, communication professions or precise technical applications: This hearing protection combines reliable attenuation with a distinctly linear sound transmission – for natural hearing, even when it gets loud. The specially developed filter technology ensures a flat, frequency-independent attenuation curve – with no loss of treble and no muffled sound. Voices and signals remain clearly intelligible and the overall sound is balanced and direct. This makes bachmaier® fidelity the ideal choice in environments where signal purity, speech intelligibility and communication in noise are crucial. With a custom-made fit, optimised filter integration, 13 colour variants and high suitability for everyday use, the bachmaier® fidelity is the right solution for anyone who wants to hear authentically even in noisy environments.
// 3 optimised designs // SNR value: max. 25 dB // high speech intelligibility // optionally with retaining strap
Whether on stage, in the studio, in technical applications or in communication – there are moments when hearing is more than just protection. This is exactly what bachmaier® fidelity was developed for. The customized hearing protection preserves what counts: Sound fidelity, speech intelligibility and presence – even at high volumes. Instead of muffling and distorting, fidelity enables a natural listening experience that protects without disturbing. The specially developed filter technology ensures clear highs, full mids and stable lows – balanced, direct and unadulterated. Whether you're rehearsing, mixing, monitoring or talking to the team: bachmaier® fidelity lets you hear what's important – while reliably protecting your hearing. For all those who don't want to do without anything – except noise.

bachmaier® fidelity classic Discreet design that sits in the ear canal and largely disappears behind the tragus – ideal for long wearing times, high sound requirements and inconspicuous applications.
bachmaier® fidelity plus Larger design, ear-filling – easy to handle and robust, ideal for those who want maximum control when inserting and removing.
Our customized silicone earmolds are particularly soft and flexible – ideal for sensitive ears and all-day use. The pleasant soft-touch surface ensures noticeably high wearing comfort, even over many hours. The material sits pressure-free, provides a reliable seal and retains its shape even during movement, heat or heavy use. Our soft-touch silicone is skin-friendly, free from plasticisers and can be easily cleaned with clean water. Silicone also offers an impressive range of colours and is particularly easy to change filter inserts – ideal for changing requirements in everyday working life. Soft remains hygienic, comfortable and reliable – day after day.
bachmaier® fidelity is available in two optimised designs – both have been specially developed to precisely integrate the high-quality filter technology while offering maximum wearing comfort.

Precision – regardless of the shape
Regardless of the chosen design, the insulating effect remains identical. Thanks to individual production and optimised filter integration, bachmaier® fidelity offers consistent protection and sound in every variant. The only decisive factor is what suits the application better: discreet fit or maximum hold.
Filters
Fidelity filters – developed for the highest demands
bachmaier® fidelity filter technology is a patented in-house development – designed for applications that require linear attenuation, maximum sound fidelity and precise speech intelligibility. Unlike conventional damping filters, bachmaier® fidelity filters do not simply block the sound – they actively control it, without electronics, purely physically.
The secret lies in the interplay of membranes, a defined volume of air and a special acoustic architecture that makes the ear canal act like a passive loudspeaker. The result: uniform attenuation across the entire frequency spectrum – highs, mids and lows remain clear, direct and true to the original.
Four filter stages – for different sound environments
All filters are colour-coded and provided with 1 to 4 tactile marking points – for quick, reliable assignment.
light
Light insulation for maximum openness and highest sound fidelity. Ideal for vocals, acoustic sets, quiet concerts or in the event of sensory overload. (Note: Does not fulfil the minimum sound insulation requirements of EN 352-2 for commercial workplaces).
medium
The balanced solution between protection and intelligibility. Perfect for event technology, medium volume work, rehearsals and communication.
strong
For loud environments with sound requirements – e.g. festivals, band rehearsals or noisy work areas with communication requirements.
maximum
Highest attenuation level – with clear, consistent sound quality. Developed for loud continuous loads – for example in monitoring, in industry or at events without compromise.
Does what it promises: the bachmaier® CUSTOMFIT cord
Quiet, comfortable and secure. Thanks to the special hydrophobic coating and the loosely woven structure of the cord, sound transmission is effectively minimised. The connecting element also offers additional protection: it loosens under extreme tensile load. Possible with bachmaier® fidelity plus and classic with handle.
Our earmolds are marked for left and right as standard. Depending on the colour of the earmold, the markings are black or white.
Personalised and individual: the custom laser marking
In addition to the serial number, we engrave a name or number of your choice on the earmold. Up to 11 characters are possible.
Easy to find: The detector ball
A corrosion-resistant and durable detector ball can be used to make the hearing protection easy to find. If the hearing protection is lost, the detector ball makes it easy to find using metal detectors.
Lacquering
Also available with a glossy lacquered surface on request (standard: matt lacquered).
Compatible
Upgrade your hearing protection with ISOtunes XTRA 2.0 (adapter necessary) or Shokz Opencom Industrial!
