M4U 8 HEADPHONE CARE

For safe, sanitary use, it is essential to maintain and clean your M4U Headphones periodically. However, excessive cleaning 
may cause damage and jeopardize the longevity of the product. When not in use, always store headphones in the supplied 
protective case, and store in a clean and dry environment. Avoid storing in extreme heat or cold temperatures and humidity, 
and avoid exposure to liquids.

Cleaning…

For regular cleaning, use a slightly damp cloth and gently clean each ear cup cushion, then use a dry cloth to remove any 
residual moisture.

If heavy cleaning is necessary after extended listening and use, follow these directions:

•  Remove the ear cup cushions according to the Cushion Attachment/Detachment instruction section following.

•  Clean the ear cup cushions by hand, using cold water.

•  Add a very small amount of dish or laundry soap and gently clean the cushions.

•  After cleaning the cushions, rinse with clean water.

•  To dry the ear cup cushions, place them on a towel with the pads facing up.

•  Fold the towel over top of the cushions and press down to remove any excess water in the foam padding.

•  Air-dry completely before reattaching.

Cushion Attachment/Detachment

1.  To detach the ear cup cushion, grasp the headband over the ear cup cushion 

that needs to be removed.

2.  Using your other hand, grip the leather ear cup cushion and carefully stretch 

and pull the ear pad away from the ear cup. Repeat on the other ear cup if 
necessary.

3.  To reattach the ear cup cushion, grip the headband and cushion as described 

above, and clip the lip of the ear cup cushion back in place. The right side 
should be installed back on the ear cup with the controls.  

NOTE:

1.  Be careful not to press down on or remove any other components inside the 

earcup as this could damage the headphones.

Storage in the protective case

1.  Remove the cable from the headphones, fold and insert them into the protective 

case.

NOTE:

•  Do not force them into the protective case.  Doing so may damage the 

headphones. 

           WARNING

When disconnecting your M4U Headphones, hold the plug at the end of the cable 
and pull to disconnect. Do not pull on the headphone cable to disconnect the 
headphones from your music player.
