CLEANING YOUR MINOR IV
Earbuds come in close contact with your skin frequently and sometimes for long periods of time. This will, over time,e cause e build-up of dirt and grease that can affect 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 affected by charging and usage. Follow the guidelines below to keep your batteries in great condition for as long as 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.
