The UnboxingTN Verdict

out of 100

The Redmi Buds 4 offer strong 30-hour endurance and USB-C charging, but their single white finish leaves little room for personal choice.

What is good

  • 30-hour battery life supports extended listening.
  • 620mAh battery capacity provides substantial onboard energy.
  • USB-C charging uses a convenient wired connector.

What is not

  • Only white color limits personalization.
  • 30-hour battery life still requires periodic recharging.
  • 620mAh capacity does not eliminate charging needs.

How the score breaks down

  • Battery 75
  • Connectivity 100

The specification sheet is incomplete, so the score stays cautious.
