Thank you for your detailed description — that’s very helpful.

What you’re hearing is likely the internal feedback or system tone emitted when the earbud detects activation or connection triggers from the case sensors or Bluetooth handshake.

To better understand it, could you please clarify:

  • Is the sound just a single short tone, or does it continue repeatedly?
  • Does it sound like a low beep, hum, or static noise?

This will help us pinpoint whether it’s a normal system indicator or a unit‑specific issue.

Yes it’s a dull soft short consistent tone(it’s as if it was from audiometric test), there is no static sound. It can happen many times randomly. It does go away when I move very far away from the case.

I’ve also got a replacement set and it’s the same issue.

Thanks for sharing the details! Based on your description, we’ve tried replicating the issue using the same steps, but we haven’t been able to reproduce it so far.

Since you mentioned that a replacement unit also shows the same behavior, it doesn’t seem to be a device-specific problem. Could you please let us know:

  • Is the environment where you use the earbuds always the same, or have you tried testing them in different locations?
  • Can you record the exact sound using some tools and share the audio with us? This would really help us understand the issue more precisely.

Thank you for your cooperation — your feedback will help us pinpoint what’s happening!
