IV. Usage Tips & Important Reminders

• 【Top Priority – Read First on Receipt】
• After long-distance logistics, the headphone battery will automatically enter a transport protection mode. 
• Please charge for 4 hours before turning it on for first use! 
• Turning it on without charging will most likely result in failure to power on, no response, or appearing dead – this is the battery protection mechanism, not a product quality issue.
• Use a standard 5V charger for charging. Do not use fast chargers or super-fast chargers – may damage the battery.
• The ear cushions are soft protein leather – avoid scratches from sharp objects. Store in a dry place when not in use.
• Do not listen at very high volume for long periods – protect your hearing.
• Before Bluetooth pairing, turn off Bluetooth on other devices to avoid cross-connection.
• TF card playback supports common audio formats only – incompatible file formats will not play.
• Do not use the headphones in high-temperature, damp, or rainy environments.
• If not used for a long time, recharge once a month to prevent battery depletion damage.
