To reduce the risk of fire or electric shock, do not expose vFree headphones to rain or moisture, and do
not open or attempt to open any part of vFree headphones.
Keep out of reach of children. Small parts may be a choking hazard. This product is not intended for use
by children under the age of three.
Excessive sound pressure from earphones and headphones can cause hearing loss.
Attention should be drawn to the environmental aspects of battery disposal.
The integrated battery should not be exposed to excessive heat such as sunshine, fire, or the like.
Consult your physician or audiologist if you have problems hearing, excessive wax build-up or any
discomfort after use of vFree headphones.
In particularly dry air conditions, mild tingling may be felt on your ears. This is a result of static electricity
accumulated in the body and not a malfunction of vFree headphones. This effect can be minimized by
wearing clothes made from natural fibers.
vFree headphones are assembled in a facility where they could come in contact with chemicals covered by
California’s Proposition 65.
If any dust or ear wax is inside the ear cup, you may experience a degradation of sound quality.
Remove vFree headphones if they cause any discomfort or pain.
Do not submerge or expose vFree headphones to water.
Protect your vFree headphones in the carrying pouch when not in use.
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
