Yes, with a reduced runtime. The difference in capacity and voltage of
rechargeable AAA compared to alkaline batteries shortens the useful run
time of the batteries by approximately 20%. The use of NiMH low-self
discharge AAA size batteries is a good match for the QuietComfort 25
Acoustic Noise Cancelling headphones for customers who prefer to use
rechargeable batteries. One thing to note is the low-battery indicator light
is not calibrated for the lower voltage of rechargeable batteries; it may
not be a reliable indicator of remaining run time, however, the
QuietComfort 25 headphones will continue to operate normally while the
light flashes until the battery is depleted.
The headphones do not require scheduled cleaning. However, if some
cleaning is necessary, gently wipe the outside surfaces with a slightly moist
cloth. Be careful not to allow any moisture to enter the headphones
through the ports or earcups. In addition, be certain not to force any dirt
or debris into the ports. Do not blow air into, or vacuum, the ports or the
interior of the earcups.
The earcup cushions are held in place by a mounting flange. That flange
snaps under eight small tabs located around the inside of the earcup. If an
earcup cushion becomes partially or completely detached, push its
mounting flange back into the earcup. Then use your finger or thumb to
press around the edge of the mounting flange, making sure it snaps in
place under all eight tabs around the earcup. If the earcup cushions are
not properly installed, the noise reduction properties of the headphones
will be diminished.
The earcup cushions have been designed using materials that should
provide years of long-lasting, comfortable performance. Replacement
cushions are offered in the event that the cushions become excessively
dirty or damaged in some way. A comfortable, effective cushion seal is
important for a great experience with your headphones.
Yes. The headphones carry a one-year limited warranty in the U.S. for
defects in materials and workmanship. We recommend you store the
headphones in their carrying case when not in use. The case will help
protect the integrity of the headphones and the high-performance
headphone speaker drivers from over-compression.
