Flanged eartip insertion
• To ease insertion, moisten the flanged eartips.
• Carefully insert one earphone at a time while pulling up and out on the back of the ear.
• Earphones should seal comfortably in the ear canals.

Foam eartip insertion
• Use a foam eartip if a good seal cannot be obtained with a flanged eartip.
• Roll down or compress foam eartips before inserting. Hold the eartip in place for about 5 seconds while the foam expands to create a tight seal in the ear canal.

Removal
Remove earphones slowly with a twisting motion to gradually break the seal. Do not pull on the cable to remove the earphones.

Cable Slider
hf5 headset + earphones can be worn with the cables in front or in back of the head. The cable slider can be adjusted by moving it up or down for a snug fit.

Caution
Consult an audiologist or physician if you have excessive ear wax, difficulty inserting the eartips, or discomfort after prolonged use.

hf5 headset + earphones exclude most external sounds. While driving, always leave one ear open. It is unsafe to use in-ear earphones while operating a motorized vehicle, operating machinery, bicycling or jogging, because you may not be alerted to potential danger.

Do not use the headset at excessively loud levels. Research confirms that earphones that seal the ear canal allow listeners to choose safer listening levels. Noise-induced hearing loss is a function of exposure time, the average sound level and the peak of very loud sounds. Sealed eartips and lower listening levels allow for longer periods of safe listening time.

Performance
A full bass response depends on proper earphone insertion. For best results, earphones must seal in the ear canals.
