CLEANING YOUR MINOR IV
Earbuds come in close contact with your skin frequently and sometimes for
long periods of time. This will over time cause build-up of dirt and grease that
can aect performance and may cause skin irritation. Clean your earbuds
regularly to keep them fresh and make them last longer.
Unplug any cables before cleaning the case. Make sure everything is
completely dry before using the earbuds, putting the earbuds back in the
case, or plugging in a USB charger.
Use a disinfectant wipe or a lint-free cloth, slightly damp with 70% isopropyl
alcohol or 75% ethyl alcohol to gently clean the exterior surfaces of the
earbuds and the case. Avoid getting moisture in any openings or in the
speaker mesh. Carefully clean those areas with a dry and soft brush, or a
cotton swab.
• Do not use any sharp objects.
• Do not use compressed air.
• Do not use products containing bleach or hydrogen peroxide.
• Do not submerge the earbuds in any cleaning agents.
BATTERY CARE GUIDE
Your earbuds come equipped with high-performance lithium-ion batteries
and battery life span is aected by charging and usage. Follow the guidelines
below to keep your batteries in great condition for as long possible.
• Avoid using fast chargers if possible. Fast charging causes stress on the
battery and will degrade it.
• Avoid letting the battery drain completely or charging it when it’s already
full. Try to keep the charge between 30% and 80%.
• If the earbuds are stored for a long time, it’s recommended to charge
the earbuds to about half-charge and then do a factory reset. Store the
earbuds and case in a cool, dark, and dry place.
• Avoid using or charging the earbuds in hot and unventilated places,
45°C/113°F and above.
• Avoid charging the battery at low temperatures, below 10°C/50°F and
using the earbuds below 0°C/32°F.
• Avoid strong mechanical shocks such as dropping the earbuds or case
on hard surfaces as it might harm the batteries.
Download the Marshall Bluetooth app and select the battery preservation
level that best suits you and your earbuds.
