The Home iB50 headphones include Active Noise Cancellation circuitry designed to reduce or eliminate
certain background noises, such as airplane engine noise, to give you a quieter, more enjoyable listening
experience. When the ANC circuit is switched ‘On’, a microphone inside each earpiece ‘listens’ for
extraneous noise that is not part of your music, and the ANC circuit then generates an opposite sound
wave designed to eliminate or greatly reduce the extraneous noise. The ANC circuit is powered by two
“AAA” batteries, included.

Listening to Music
The battery compartment is located inside the R earpiece. To open the battery compartment cover, press
with your thumb at the top of the cover as shown to release the locking tab and slide the cover downward
to remove it.
Insert the two “AAA” batteries into the battery compartment as
shown. Be sure to install the batteries in the correct polarity (+/-)
according to the markings in the battery compartment. If the
batteries are inserted incorrectly the ANC circuit will not operate.
• Before putting on your headphones, we recommend that you rotate the volume control on the
headphone cable counter-clockwise until it is approximately half way between the Minimum and
Maximum levels.
• Begin playback of your external music source and adjust the volume level of your external device
to approximately 50% of maximum volume.
• Place the iB50 headphones on your head according to the L and R markings on the earpieces.
When worn properly the detachable cable will be on your left side. Slide the L and R earpieces
up or down to achieve the most comfortable fit.
• Adjust the volume controls on the headphone cable and your external device to a comfortable
listening level. Note: If one control is set too high and the other is set too low, the sound may be
distorted.
• To reduce or eliminate extraneous noise, such as the engine roar in an airplane cabin, slide the
ANC On/Off switch the ‘On’ position. The ANC LED indicator turns red when the ANC circuit is
‘On’.
After installing the batteries, replace the battery compartment
cover and make sure it is completely flat against the earpiece with
no gap at the bottom.
Batteries information
• Do not mix old and new batteries.
• Do not mix alkaline, standard (carbone-zinc) or
rechargeable (nickel-cadmium) batteries.
• When you are finished listening slide the ANC switch to the ‘Off’ position to extend the life of the
batteries. The ANC LED indicator goes ‘Off’. Also remember to shut off the power of your external
music source.
Replacing the Batteries
The two “AAA” batteries should provide over 60 hours of continuous operation with the ANC circuit
‘On’. If you notice that the ANC circuit is no longer providing any noticeable noise reduction, or that
the ANC LED indicator does not turn ‘On’, it’s time to replace the batteries.
Using The Mute Button (Only When ANC is 'On')
Depress the Mute button on the L earpiece to temporarily shut off the sound so that you can hear
someone speaking to you without removing the headphones. Release the Mute button to resume
normal operation.
We recommend that you use a well-known brand of alkaline batteries for longest life and best
performance.
Follow the ‘Installing The Batteries’ instructions above to replace the batteries.
Using the 2-Prong Airline Adapter
Some older aircraft have audio/visual systems that use dual
headphone jacks in the armrests of their seats. To use your iB50
headphones with this type of A/V system, insert the plug of the
headphone cable into the jack of the included 2-prong adapter as
shown and insert the 2-prong adapter into the dual jacks in the
armrest of your seat.
Connect The Detachable Cable
Connect the detachable headphone cable to the jack on the
bottom of the L earpiece. The cable should be connected with
the in-line volume control closest to the L earpiece as shown.
Make sure that the plug is fully inserted into the jack. If the plug is
not fully inserted the sound may be intermittent, or you may only
hear sound from one of the earpieces.

To keep your headphones clean, store them in the included travel pouch when not in use. The L and
R earpieces fold flat for convenient storage.
our factory.
Connect the other end of the detachable cable to the headphone jack of your external music source such
as an iPod, iPhone, iPad, MP3 player, personal CD player, etc. Again, make sure that the plug on the
detachable cable is fully inserted into the headphone jack of your external music source.
