Is it safe to use the Redmi Buds 4 Lite at high volume for long periods?
No, the manual warns that to prevent possible hearing loss, you should not use high volume for long periods of time. If skin contact areas show signs of redness or swelling during use, you should stop using the product immediately and seek medical assistance.
