Introduction

Thank you for purchasing ISOtunes® Sport DEFY Professional Noise Isolating Earmuffs. These earmuffs have been specifically designed for use in noisy environments – allowing you to block out much of the surrounding noise so that you can listen to your music or talk on the phone with less interruption. This product has been tested and meets the European Safety Standard EN352-1:2002 and the ANSI & NIOSH standards for a hearing protector, with a Single Number Rating (SNR) of 30 dB with a Noise Reduction Rating (NRR) of 25 dB. Full testing details are available in the Noise Attenuation section of this booklet.

Noise Attenuation APPROVAL
ISOtunes® Sport DEFY is tested and approved in accordance with ANSI S3.19-1974 Specifications and the European Safety Standard EN 352-1:2002.

ANSI
S3.19-1974
The level of noise entering a person’s ear, when ISOtunes® Sport DEFY headphones are worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the Noise Reduction Rating (NRR). Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fitting.
A1: Frequency (Hz)
A2: Mean Attenuation (dB)
A3: Standard Deviation (dB)

Example:

The surrounding noise level measured at the ear is 100 dB.
The NRR of ISOtunes® Sport DEFY is 25 dB.
The noise level entering the ear is approximately equal to 75dB.

Please note that the NRR is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attain-able against impulsive noise, such as gunfire.

B1: Frequency (Hz)
B2: Mean Attenuation (dB)
B3: Standard Deviation (dB)
B4: Assumed Protection Value (APV) (dB)
B5:
- H = Hearing protection estimation for high frequency sounds (f ≥ 2000Hz)
- M = Hearing protection estimation for medium frequency sounds (500 Hz < f < 2000Hz)
- L = Hearing protection estimation for low frequency sounds (f ≤ 500Hz)

SafeMax™ Technology
ISOtunes® Sport DEFY incorporates SafeMax™ Technology, there-fore its volume output has been limited to 85 decibels. ISOtunes® devices with SafeMax™ Technology are OSHA, NIOSH, and ANSI compliant and, when designated, meet the European Safety Stan-dard EN352.

Tactical Sound Control™ Technology
This product includes TSC – Tactical Sound Control. This is a mi-crophone technology that allows the user to hear the world around them, but always at a safe listening level. When ambient noise breaches a safe listening level, the microphone technology immedi-ately responds and attenuates to a safe level.
This feature automatically turns on when the product turns on. Ad-justing the TSC volume is easy. Simply press the TSC Volume Up and Down Button.
