HaJoW The RDA5807 (not RDA5807M!) is stereo but only OUT R (7) is used to power one amplifier. You could use a second speaker by doubling the circuit around the OP-Amp and connect it with OUT L (8). Datasheet https:##www.alldatasheet.com#datasheet-pdf#pdf#1253730#ETC1#RDA5807.html (Replace # by slash as external links are forbidden) RDA5807 should directly drive 32 Ohms European headsets.
