ETY•COM™ headset

Instructions

Important things to know about the ETY•COM™ Headset:

For best results, it is essential that the earphone and the microphone are placed in the optimal position.

• Eartip selection is critical to success with the headset. The ETY•COM comes with an assortment of eartips; select an eartip that allows the earphone to seal the ear canal. Moisten the eartip if necessary to ease insertion. The eartip should stay in position so the boom does not rotate downward during use.
• The ETY•COM microphone is highly directional. It picks up your voice within a narrow range and rejects background noise coming from outside that range. To stay in this range, the boom should be bent so that the microphone is within 1/2 inch of your mouth; otherwise the microphone will reject your voice.

If the headset volume decreases or the sound quality declines, change the filter.

Care

• Do not expose to extreme temperatures.
• Avoid dropping and strong impact.
• Leave eartip on the headset for shock protection.
• Clean or replace eartips prior to use by others.

Cleaning and Replacing Eartips

Over time eartips may lose their elasticity. For best performance and retention, replace 3-flange eartips every 3-6 months. Replace foam and glider eartips regularly.

To clean the 3-flange eartips:

• Remove the eartip from the headset.
• Clean with water and mild soap.
• Dry the eartip before placing it back on the headset.

About the Filters

The ETY•COM has a special filter that smoothes the frequency response and prevents earwax from entering the earphone. The filter is located at the end of the headset and is visible when the eartip is removed. A dirty filter will reduce or block the headset output. The need to change filters varies widely among users.

1. Remove eartip	2. Remove filter with tool	3. Insert new filter provided

4. Gently press into place	5. Attach eartip

Exceptional Sound Quality

• ETY•COM's high-fidelity earphone (similar to the ER•6 that is designed for accurate music reproduction) provides noticeably better sound quality than ordinary headsets.
• Frequency response extends beyond the typical low-fidelity telephone bandwidth.
• The headset smooths the peaks in the frequency response that ordinarily make sounds harsh and uncomfortable at loud volume levels.

Unsurpassed Noise Isolation

Provides the highest sound isolation of any mobile phone headset:

• Noise reduction = 37 dB, averaged over octave frequencies from 124-8000 Hz.
• Noise Reduction Rating (NRR) = 24 dB with orange foam eartip, and NRR = 27 dB with new black foam eartip, as measured by independent E-A-R CAL Laboratory (Indianapolis, IN).
• Allows only the audio from the caller to enter the ear.

Highly Directional, Noise-Canceling Microphone

• The ETY•COM's highly directional microphone is positioned close to the mouth for best clarity and maximum rejection of background noise.
• Up to 25 dB more noise rejection than boom mics that are not close to the mouth.
• 4 to 11 dB greater noise rejection than other microphones in the same location.
• Allows you to speak softly for greater privacy.
