Remember, the snugger the fit, the better the noise blocking. The silicone ear tips are intended for use when NOT in noisy situations.
Isotone’s® TRILOGY™ foam ear tips have a threaded core and the sound port on the earbud is also threaded.

1.Twist the foam ear tip counterclockwise to remove and clockwise to place on a new foam ear tip.
2. Carefully compress the foam ear tip on the stem/sound port.
3. Insert the foam/ear tip into your ear as deeply as is comfortable and hold for 5 seconds while the foam expands.
4. Repeat with second ear tip.

Hint:
To open your ear canal wider, lift the top of your ear up and away from your head, as shown in FIG1.

Introduction

Thank you for purchasing ISOtunes® XTRA 2.0 Professional Noise Isolating headphones. These headphones 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 EN352-2:2002 and the ANSI & NIOSH standards for a hearing protector, with a Single Number Rating (SNR) of 36 dB and a Noise Reduction Rating (NRR) of 27 dB. Full testing details are available in the Noise Attenuation section of this booklet.

Noise Attenuation

APPROVAL: Isotone’s® XTRA 2.0 is tested and approved in accordance with ANSI S3.19-1974 Specifications and the European Safety Standard EN 352-2:2002.

ANSI
S3.19-1974
The level of noise entering a person’s ear, when Isotone’s® XTRA 2.0 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:

1. The surrounding noise level measured at the ear is 100 db.
2. The NRR of Isotone’s® XTRA 2.0 is 27 db.
3. The noise level entering the ear is approximately equal to 73dB.

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

EN352

• 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)
