For regular users, we recommend replacing ear cushions, fabric lining, and foam inserts every 3-9 months depending on the frequency of use.


In order to provide you with the promised hearing protection and the best sound quality, the earmuffs should fit snugly.

A Noise Reduction Rating (NRR) measures the amount of hearing protection or attenuation provided by different hearing protectors. Measured in decibels (dB), the NRR of a hearing protector must be determined in a lab and approved by the American National Standards (ANSI) in accordance with the Occupational Safety & Health Administration(OSHA). ISOtunes products use industrial grade memory foam to block 22-29 dB of damaging noise, which means you can work in loud environments knowing your ears are protected.

For hearing protection, ISOtunes are tested and approved in accordance with ANSI S3.19-1974 specifications. Additionally, ISOtunes SafeMax Technology built into every product ensures maximum volume output of 85 dB*, OSHA's identified level of safe sound exposure throughout a work day. As such, all ISOtunes products meet OSHA and NIOSH requirements to be used as hearing protectors in the workplace. Beyond hearing protection, all ISOtunes products are tested to IEC standard 60529 for International Protection Markings, which rate the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water.

*Unless otherwise specified. Lower volume products are available.

Use in the workplace

All ISOtunes products are certified hearing protection devices, designed to reduce environmental noise and protect wearers in harmfully loud environments. Many ISOtunes products also provide communication capabilities for enhanced productivity. In use cases where situational awareness is essential, we would recommend using our active hearing protectors with ambient listening capabilities, indicated by Aware Technology or Tactical Sound Control. The user is solely responsible for ensuring any ISOtunes product is used safely.

All ISOtunes products are tested in NVLAP labs to ANSI and EPA hearing protection standards and issued Noise Reduction Ratings (NRRs) accordingly. Additionally, all ISOtunes products are OSHA compliant, meeting both hearing protection and hearing conservation standards for a full day of use in the workplace.

That said, each workplace may have its own specific rules and restrictions on what hearing protection devices can, cannot, or must be used to prevent hearing loss. For most facilities, a sufficient Noise Reduction Rating should fulfill the most important requirements

If you're unsure, simply ask your manager or company’s Safety Official to determine whether or not ISOtunes products are suitable for your workplace. When using ISOtunes products, please abide by the rules established by your place of employment.

Contact us if you would like more information about getting ISOtunes approved for your workplace.

Aware Technology

It depends. Aware Technology™ amplifies outside noises through omni-directional microphones. If you are hearing static or white noise, Aware Technology™ is likely magnifying sounds from your surroundings. This is considered normal. As with most hearing aids or enhancers, it may take time for you to adjust to the enhanced sound. We suggest you test the product with the Aware Technology™ turned off. If you still hear static noise, we consider this a product defect and you should contact our customer service for support.

Aware Technology™ is great for communicating in sporadically loud environments. Noises like nail guns and hammers will be blocked by Aware Technology™, while safe environmental sounds will be amplified. Aware Technology™ is especially helpful in environments where enhanced situational awareness is necessary.

Aware Technology™ is not well suited for consistently loud environments. When exposed to steady-state noise above 85dB, Aware Technology™ will passively block all outside sound, similar to a standard hearing protector. Aware Technology™ will not amplify outside noise until the steady state-noise ends or falls below 85dB. In these cases, we recommend turning Aware Technology™ completely off until you’re done working in that environment.

ISOtunes Aware Technology™ and ISOtunes Sport Tactical Sound Control™ are both developed to handle loud impulse noises. Both of them allow you to maintain situational awareness without risking hearing loss. The terms differ to better relate to the industries that we built them to live in. ISOtunes involves itself in woodworking, construction, lawn care, and industrial spaces. ISOtunes Sport finds its home at ranges and with outdoor hobbyists. The products vary in color and name, but we guarantee the same amazing experience and protection with each of them.
