Battery Life and Replacement with the Active M4U Headphones
The 3-Position Power Switch will be “AMBER” to indicate to the listener that there
is approximately 3 hours of battery life remaining. Although battery life will vary
upon usage, the average life is 55 hours (which may vary further if using recharge-
able batteries).
Upon needing replacement, simply grasp the headband and tilt the top of the
left ear cup towards the right side to locate the two pull-tabs on the bottom as
indicated in Figure 4. Placing two fingers inside both tabs, gently detach the battery
compartment cover, and replace the used batter-
ies with two AAA alkaline batteries (IEC LR03)
as illustrated in Figure 5.
To reattach the front cover piece, insert the top
two clips first, and proceed to press the remain-
ing two clips into the provided slots.
Battery Life with the M4U 8 Headphones
The 3-Position Power Switch will start flashing to indicate to the listener that there
is approximately 1 hour of battery life remaining. Although battery life will vary, the
average life is 15 hours.
Please dispose of used batteries properly, following any local regulations. Do not incinerate.
PROTECTING YOUR INVESTMENT….
For long lasting enjoyment of your headphones, you should respect their limits and avoid excessive volume levels for music
or movie playback. Excessive volume levels can damage all headphones.
If your headphones are pushed to excessive volume levels, they could be driven into “clipping”. This could result in severe
or permanent injury. When using your headphones at loud levels, listen carefully for any sign of harsh, garbled midrange
and diminishing intelligibility. If detected, turn the volume down immediately.
NEVER TEST PEAK LISTENING LEVELS OF THE HEADPHONES BY TURNING THE VOLUME UP ALL THE WAY!
