Volume Adjustment
When using the earphones with the iPod via the adapter, the volume adjustment is made
on the earphones, not on the iPod. This ensures the highest quality signal at the
earphones.
Charging the Earphones
Charge the earphones for at least one hour before first use. A complete charge from a near-
empty battery will take about two hours. When charging, the LED glows yellow. When charging
is complete, the LED glows green if the unit is on. If the unit is off, the LED turns off when
charging is complete.
Overcharging
It is not possible to overcharge the earphones.
Battery life
•
•
Up to 10 hours of listening time, depending on the iPod or other device.
When there is less than one hour of use left, the LED slowly blinks green.
Auto Shut Off:
If the earphones are turned on but there is no music playing, the earphones will turn off after five
minutes.
Charging the Made for iPod® Adapter
The Made for iPod® adapter uses the power provided by the iPod battery and does not need
charging. Since it uses the iPod battery, use of the Made for iPod® adapter will reduce the
battery life of the iPod.
Using the Earphones
Power On with an iPod
•
•
iPod should be OFF.
Press the On/Play/Pause button for three seconds to turn the earphones on. The green
LED will light when the earphones are turned on.
•
•
Plug the adapter into the iPod.
When the earphones have connected to the iPod source and the device is playing audio,
the Made for iPod® adapter LED glows green.
•
The following key presses are available to the user from the earphone:
1. Play/Pause
2. Volume Up
3. Volume Down
4. Previous Track
5. Next Track
Power Off
While the earphones are on, press the On/Play/Pause button for three seconds to turn
•
the earphones off. The green LED goes out when the earphones are turned off.

Troubleshooting
Problem: No Music is playing through the earphones:
•
•
•
•
Make sure the earphones and iPod adapter are on.
Make sure the iPod is powered.
If the iPod shows paused on its display, press play.
If the iPod shows playing , press play/pause on the iPod TWICE.
Problem: The music is breaking up.
•
When indoors, you will have the best reception when the earphones are in the same
room as the iPod.
•
You will have the best reception if the iPod is worn closest to the earphone side with
on/off control.
•
PTIONAL ACCESSORIES
Insertion of Earphones
Try the 3-flange and foam eartips to determine the best fit for comfort and isolation. Sound quality
and noise isolation depend on how well the eartips seal. If the earphones seem to lack bass,
insert the earplug deeper into the ear canal to obtain a better seal, or try the other eartips
supplied with these earphones.
Two and 3-flange eartip insertion
• For best results, moisten the plastic eartip before insertion.
• Carefully insert one earphone at a time, pulling up and out on the back of the ear. This
straightens the ear canal to ease insertion. It is also helpful to open the jaw slightly. The
earphone should seal deeply and comfortably in the ear canal.
Foam eartip insertion
• Use a foam eartip if a good seal cannot be obtained with a flanged eartip.
• Compress the foam at the end of the earphone by rolling it between your thumb and forefinger
before inserting it. Hold the earphone in the ear for about 5 seconds while the foam expands to
create a tight seal in the ear canal.
Removal
When a good eartip seal is achieved, suction can sometimes be created when removing the
earphones. To avoid discomfort, use a slow twisting motion to gradually break the seal. Open the
jaw slightly to equalize pressure. REMOVAL
CHANGING FILTERS
Earphone Filters
Ety8 Earphones have special filters that shape the frequency response and prevent earwax from
entering the earphones. These filters, identified by a white acoustic mesh in a small red plastic
barrel, are located at the end of the earphone and are visible when the eartip is removed. When
the filters become clogged they should be replaced. A dirty filter will reduce or block the earphone
output. The frequency with which the filters need to be changed varies widely among users. The
filters should be changed if the volume decreases or the sound quality declines.
Changing Filters SHOW with diagrams and arrows
1. Remove eartip
2. Remove filter with tool supplied
3. Insert s new filter
4. Gently press flush against flat surface

Proper Care
[[[PROPER CARE
•
•
•
•
Do not expose earphones to extreme temperatures.
Avoid dropping or strong impact. Extreme shock can damage the earphones.
Always leave an eartip on the earphone for shock protection.
Keep earphones away from water as this can adversely affect sound quality. Perspiration
entering the nozzle may cause the earphone to temporarily stop working. Normal
operation usually returns after the earphone dries out.
Do not pull on the cord to remove it from the jack or from the ear.
Avoid bending the barrel in the center of the cord.
Clean or replace the white 3-flange eartips prior to use by others.
Replace disposable foam eartips regularly.
Earwax buildup can reduce the earphone output. When the filters become clogged they
should be replaced.

NE ISOLATION
Cleaning
The 2- and 3-flange reusable eartips should be cleaned regularly.
1. Carefully remove the eartip from the earphone.
2. Use water and mild soap to remove dirt and earwax from the eartip.
3. Rinse and completely dry the eartip.
4. With a slight twisting motion, push the eartip back onto the earphone until it fits securely
5. Foam eartips: Discard dirty eartips and replace with new ones.
Cautions
Consult a physician or audiologist if you have excessive earwax, difficulty inserting the eartips, or
discomfort after prolonged use. Ety8 Bluetooth earphones exclude most external sounds even at
low listening volumes. It is unsafe to use insert earphones while driving a motorized vehicle,
operating machinery, bicycling or jogging, because you may not be alerted to potential danger.
Do not use the earphones at excessively loud levels. Noise-induced hearing loss is a function of
exposure time, the average sound level and the peak of very loud sounds. Decreased listening
levels allow for longer periods of safe listening time.
Listen Safely
Noise reduction with ety8 Bluetooth earphones occurs naturally when the eartips seal in the ear
canals. Well-sealed Etymotic insert earphones provide 35 dB average external noise isolation
with both flanged and foam eartips. Research indicates that preferred listening levels are lower
when it is not necessary to overcome background noise in the environment. Reduction of
surrounding noise with noise isolating earphones allows the listener to hear the full dynamic
range of recordings at lower levels, which reduces the risk of noise-induced hearing loss. ABOUT

1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause
undesired operation.
These limits are designed to provide reasonable protection against harmful interference in a
residential installation. Some equipment operates at frequencies that may cause interference to
nearby TVs and VCRs; to minimize or prevent such interference, the system base should not be
placed near or on top of a TV, PC monitor, or VCR; and, if interference is experienced, moving
the desk station farther away from the TV or VCR will often reduce or eliminate the interference.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the system off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
1. Increase the separation between the equipment and receiver.
2. Consult the dealer or an experienced radio TV technician for help.
