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. 

Installing The Batteries

Although the headphones can be used 

without batteries, the Active Noise Cancel-

lation circuit will not operate unless the 

batteries are properly installed.
Note: The ANC On/Off switch was set to 

the ‘Off’ position at our factory.

 

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.

Note: The volume control on the cable was set at ‘Maximum’ at 

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.

•  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’.

•  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.

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.

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. 

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.

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. 

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.  

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.

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.
