Sport Ear Buds with Detachable Ear Hooks and Modular Cord System

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.
