Einleitung

The Matsunichi M97’s speakers are behind a thin piece of metal, and after a drop or after extended use, the speakers may begin to sound tinny or may discontinue to make sound entirely. With this, disassembly of the device may be necessary to diagnose or fix any issues within the speakers themselves. For more information on soldering, please visit the How to Solder and Desolder Connections guide.
