The JBL Wireless Microphone set allows 2 x wireless microphones* to be connected to any Partybox model ** through the use of a dongle connected to the Mic input. Additionally, a 3rd wired microphone - like the JBL PBM100 Wired Microphone, can also be connected to the switchable Guitar/Mic 2 input (only available on some Partybox models). This will also work when using the non-switchable Guitar input on other Partybox models - however, this will bypass the karaoke effects including echo for the connected microphone and would generally have a slightly different sound character/timbre to a microphone connected to the Microphone input.

*This includes the Partybox On-The-Go, a maximum of 2 wireless microphones can be connected and used simultaneously. The standard bundled Partybox On-The-Go microphone can only be connected to the Partybox On-The-Go that it came bundled with, it also cannot connect wirelessly to any other Partybox models or portable speakers other than the Partybox On-The-Go that it came bundled with. Only one standard, bundled Partybox On-The-Go wireless microphone can be connected at a time, unless the JBL Wireless Microphone is purchased (sold separately), a spare part will only work as a replacement, not simultaneously.
