Limited 2 Year Warranty
Using Your New Balance Sport Ear Buds
Your ear buds are assembled into the ear hooks at the time of purchase. You may use the ear buds together
with the hooks for a more secure fit while performing strenuous exercise, or detach the ear buds from the
hooks when the hooks are not required.
Your ear buds are also supplied with two
additional sets of “NB” decorative caps in
different colors so that you can customize
the appearance of your ear buds to your
own personal taste.
The earpieces are marked “L” and “R”. Place the “L” earpiece in your left ear and the “R” earpiece in your
right ear for proper fit and best sound. If the earpieces are inserted incorrectly they will not fit properly in your
ears and the sound quality may not be satisfactory. This model features an asymmetrical cord design. When
worn properly the headphone plug will be closer to the “L” ear bud.
Your New Balance Sport Ear Buds are supplied with three sets of silicon tips
(S, M and L). The ‘M’ size tips were installed at our factory. If you find that the
‘M’ size tips are either too large or too small for your ears you may change to
the ‘S’ or ‘L’ size tips. To change the tips, carefully pull the installed tips off the
earpieces and push the new tips on to the earpieces as shown in the
illustration.
IMPORTANT: Make sure that the new tips are fully seated on the earpieces so that the tips do not come off
when you remove the earpieces from your ears. If one of the tips remains in your ear canal and you cannot
easily remove it, seek medical attention to avoid forcing the tip further into your ear canal.
Your New Balance Sport Ear Buds were designed with a modular cord system. We have provided a 15”
cable with an in-line volume control that is suitable if your music player will be worn in an armband or clipped
to your clothing at chest level. We have also provided a 36” cable that is suitable if your music player will be
clipped to your belt, placed in your pocket or carried in a fanny-pack.
Connect the male headphone plug of the ear buds to the female headphone jack of either the 15” or 36”
headphone cable depending on your wearing preference. Then connect the male headphone plug of the
15” or 36” cable to the headphone jack of your music player. Be sure that the plugs are fully inserted into
the jacks. If the plug is not fully inserted you may only hear sound from one earpiece
Using the In-Line Volume Control
You may have to adjust the volume control on your music player as well as the In-Line Volume Control on
your headphones to find the most satisfactory sound level. If one control is set too low and the other is set
too high, the sound may be distorted. Try setting the volume control on your music player halfway between
the Min and Max settings, and then use the In-Line Volume Control on your New Balance headphones to
make final adjustments.
Using the Accessory Cord Winder Clip
Your New Balance Ear Buds are also supplied with a cord winder clip that may be used to eliminate excess
slack in the 36” cable if necessary. If you find that that the 36” cable is too long you can store up to 24” of
cable in the cord winder and then clip the cord winder to your clothing.
Using the Water Resistant Connection Cover
Your New Balance Ear Buds are also supplied with a silicon sleeve that can be used to cover the
connection between the male headphone plug on the Ear Buds and the female headphone jack on
the 15” or 36” cable. Use this connection cover if you routinely use your Ear Buds in extremely wet
or damp conditions.
Stretch the connection cover over the plug of the Ear Buds
as shown. After connecting the male plug of the Ear Buds to
the female jack on the 15” or 36” cable. Slide the connection
cover down so that it completely covers the plug and jack
connection point to seal out excess moisture.
Safety Information
To protect your hearing, always start listening with the
Volume Control of your music player set to a low level and
gradually increase the volume to a comfortable listening level.
IMPORTANT! Listening at high volume for long periods of
time can result in long-term hearing damage. For your safety,
do not use headphones if they would prevent you from
hearing warning sounds, such as while driving a car or
motorcycle, riding a bike, etc.
NOTE: In extremely cold or dry air conditions you may notice
a slight ‘tingling’ feeling in your ears when using in-ear
headphones. This is the result of the build-up of static
electricity in your body. This is normal and not an indication of
any problem with your headphones.
