The left earbud has a static/crackling noise issue when using Transparency Mode or Noise Cancellation. The right earbud works normally.

When Transparency Mode and Noise Cancellation are turned off, both earbuds can still be used as regular AirPods for music, videos, and calls.

Condition:
- Always kept in a protective case
- No scratches, dents, or major cosmetic damage on the earbuds or charging case
- Clean and well cared for
- Includes original box and accessories

Battery:
- Battery life is still good for daily use
- Approximately 4–5 hours of listening time on a single charge, based on my experience
- Charging case provides multiple additional recharges

Please review the description carefully and purchase only if you understand the issue with the left earbud in Transparency and Noise Cancellation modes.
