Maintenance

Cleaning Your Minor IV

Earbuds come in close contact with your skin frequently and sometimes for long periods. This can lead to build-up of dirt and grease, affecting performance and potentially causing skin irritation. Clean your earbuds regularly to keep them fresh and make them last longer.

Unplug any cables before cleaning the case. Ensure everything is completely dry before using the earbuds, putting them 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 these areas with a dry, 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 are equipped with high-performance lithium-ion batteries. 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 them to about half-charge and then perform 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.

Minor IV can be connected with two devices at a time and remembers up to 8 previously paired devices. When in range, they will try to reconnect with the last connected device.
