Left speaker is substantially lower in volume compared to the right. The speaker does not crack or pop as if it's busted it just doesn't match the volume level of the other speaker. There has been repairs made to the folding hinge, bigger screws were required after the original screws wore out.

This headset would be perfect for someone looking for a parts or repair unit with a good speaker battery or Bluetooth main board.

Aside from the issues with the volume everything else is working perfectly on this headset.
