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.
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.

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.
