If you're experiencing adverse reactions while wearing the Redmi Buds 4, please refer to the following troubleshooting steps:
1. Ensure that the buds are properly fitted in your ears. Poorly fitting ear tips can cause discomfort or irritation, especially during extended use. Try adjusting the ear tips;
2. The buildup of dirt, earwax, or debris on the earbuds can cause irritation or allergic reactions. Clean the buds thoroughly using a soft, dry cloth or a mild cleaning solution;
3. If you're experiencing discomfort from wearing the buds for an extended period, take regular breaks to give your ears a rest;
4. The earphone volume should not be too loud. Using too loud for a long time will fatigue your hearing and ear canal nerves, and will easily make your ears feel pain and soreness. It is recommended that you lower the volume;
5. If you suspect that you may be allergic to the materials used in the buds, such as silicone ear tips or plastic components, discontinue use and consult a healthcare professional if necessary.
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
