Care and Maintenance

To ensure longevity and optimal performance of your Fulext Sleep Headphones, regular care is essential. Periodically disassemble the unit for thorough cleaning. Carefully remove the Bluetooth module and detach the red and black plugs from the cord – a small wrench aids this process.
Hand wash the headband with a mild detergent and lukewarm water. Avoid harsh chemicals or abrasive cleaners; Ensure all components are completely dry before reassembly. Proper storage in a cool, dry place will also extend the lifespan of your headphones.
Disassembly for Cleaning
Maintaining hygiene is crucial with sleep headphones. Begin disassembly by gently removing the central Bluetooth module from the headband. Locate the two plugs – typically red and black – connecting the module to the cord. Utilize the provided small wrench to carefully extract these plugs, separating the module.
If the wrench is misplaced, exercise extreme caution to avoid damaging the connections. Disassembly allows for focused cleaning of both the headband fabric and the module itself, ensuring a fresh and comfortable experience.
Cleaning Instructions for the Headband
To clean the headband, gently hand wash it with a mild detergent and cool water. Avoid harsh chemicals or bleach, as these can damage the fabric and potentially the embedded speakers. After washing, rinse thoroughly to remove all soap residue.
Air dry the headband completely before reassembling it with the Bluetooth module. Do not use a dryer, as heat can cause shrinkage or damage. Regular cleaning ensures a comfortable and hygienic sleep experience, prolonging the life of your Fulext headphones.
Storage Recommendations
For optimal longevity, store your Fulext Sleep Headphones in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing the headband while it’s still damp, ensuring it’s completely dry before putting it away.
When not in use, consider storing the headphones in a protective pouch or case to prevent dust accumulation and potential damage. Disassembling the Bluetooth module and storing it separately can also help protect the sensitive electronics. Proper storage maintains performance and extends the lifespan of your device.
Troubleshooting Common Issues
Experiencing difficulties? This section addresses frequent problems. For Bluetooth connection issues, ensure the headphones are charged and in pairing mode, then re-scan on your device. Poor sound quality often stems from low volume or a weak Bluetooth signal – try adjusting settings and moving closer to your device.
If the headphones won’t power on, charge them for at least 30 minutes. If problems persist, consult the FAQ or contact customer support. Disassembly for cleaning, if done incorrectly, can also cause issues.
Bluetooth Connection Problems

Difficulty pairing? First, confirm Bluetooth is enabled on your device. Ensure the Fulext headphones are in pairing mode – typically indicated by a flashing light. If still unsuccessful, “forget” or remove the headphones from your device’s Bluetooth list and re-scan. Interference from other devices can also disrupt the connection; move away from potential sources.
Check compatibility with your device. Restarting both the headphones and your device often resolves connection glitches. A weak signal can cause dropouts; stay within range.
Sound Quality Issues

Experiencing muffled or distorted audio? Verify the volume levels on both your Fulext headphones and the connected device. Ensure a stable Bluetooth connection, as interruptions can affect sound. Check the audio source; a low-quality file will naturally sound poor. The snug fit is crucial – adjust the headband for optimal speaker positioning against your ears.
Clean the speakers gently to remove any obstructions. Try a different audio source to isolate the problem. If issues persist, reset the headphones to factory settings (consult the manual for instructions).

Power Issues
Headphones won’t turn on? First, confirm sufficient charge by connecting to a power source using the provided charging cable. Allow ample charging time – a full charge may take several hours. If charging doesn’t resolve the issue, try a different USB cable and adapter. A flashing light usually indicates charging; no light may signal a deeper problem.
Unexpected shutdowns? Ensure the headphones aren’t exposed to extreme temperatures. Battery life diminishes over time; consider this if the issue is gradual. Contact customer support if problems persist despite troubleshooting.
