Bluetooth is a short-distance
two-way wireless communication technology
capable of transmitting data, commands, and audio
between devices. The Metro can connect with many devices such
as mobile phones, tablets, PDAs, computers, media players, and
more. Before you can use your Metro with your device they will
need to be paired.
Bluetooth Information

Turn down the volume prior to using the headphones; adjust the
volume to the desired level once they are connected. Do not use
headphones at high volumes for extended periods of time as doing so
will result in permanent hearing damage. It is advised you keep
volume levels moderate to low at all times for your safety, even when
loud background noise is present.
Please visit www.osha.gov for more info.
Follow all laws governing use of headsets while driving, cycling,
walking, and/or running. Do not insert both earphones while driving a
car, cycling, operating machinery, or performing other activities that
require hearing surrounding sounds.

Care and Safety
Do not use your wireless headset around flammable gases
as fire or explosion may occur.
Keep the device and packaging out of the reach of children.
There are no user replaceable/reparable parts in the
headset. Disassembling it will void your warranty.
Do not expose the headset to moisture, sweat, water, or
other liquids, or excessive heat such as fire.
Do not drop as the internal circuit could be damaged.

Cleaning the Metro
Storage
When not in use or charging, please store the Metro in the
included carrying case. Storing the Metro in a pocket or bag
without using the case may decrease the lifespan of the
Metro.
Over time, the Metro may need to be cleaned. Most debris
can be cleaned off the Metro with a soft, dry cloth. For stuck
on debris, wipe with a cloth dampened with soapy water and
then again with a cloth dampened with water. Using chemical
cleaners on the Metro may cause discoloration and hardening
of the cable.

Changing and Cleaning Ear Tips
The Metro is an in-ear headphone that requires the ear tips to
seal with your ear canal. Three sizes of specially-made ear tips
are included to help you achieve the best fit and comfort. A
proper seal between the ear tip and ear canal is important for
getting the best sound.
Please try the ear tips you think will fit best to make sure you are
getting the best seal and comfort.
Removing Ear Tips
Hold the ear tip firmly in one hand and the earpiece in the
other
With a firm grip on the ear tip, pull away from the earpiece at
a 45 degree angle until you see the large part of the nozzle
Pull straight off the ear tip

Cleaning Ear Tips
Caution:
Always make sure ear tips are installed properly on the earphone
nozzle to avoid an ear tip coming off in your ear. Frequent
cleaning of the outer portion of the nozzle and inside the stalk of
the ear tips will help keep them in place.
Remove the ear tips from your earphone as instructed
on page 9
Take a cotton swab that is either dry or has been dampened
by a small amount of rubbing alcohol or hydrogen peroxide
on it (soapy water is OK)
Swab around the nozzle of the earphone
Swab the ear tip including the inside of the stalk
Note: Ear tips can also be submerged fully in rubbing alcohol or
hydrogen peroxide
Wait for the earphones and ear tips to dry completely
Put the tips back on the earphone, making sure they are fitted
securely

Using the Ear Fins
The Metro comes with two sets of ear fins
to help keep the Metro in place.
Installing the Ear Fins on the Metro
If the ear fins slip off the earphone housing, clean the earphone
housing and ear fins with the same method found in the
Cleaning Ear Tips section.
Choose the size that will best fit your ears
a)
The ear fin rings are tapered; side with the
larger opening should be oriented toward
the earphone housing
Slide the ear fin on the earphone housing
and position it 3-4 mm (about 1/8”) from
the end of the earphone housing; it will be
necessary to stretch the ear fin a bit
Adjust the fin positioning to lock the
Metro in place
