The JBL PartyBox 2 Wireless Handheld Microphone System (model JBLPBWIRELESSMICAM) is a dual-mic kit designed to enhance karaoke, duets, announcements, or live performances when paired with JBL PartyBox speakers. Released in late 2023 as an upgrade to earlier wired options, it features digital wireless technology for cord-free operation up to 100 feet (30 meters), making it perfect for indoor/outdoor parties. The system includes two rechargeable handheld mics and a dual-channel receiver dongle that plugs into the speaker’s 1/4″ mic input. It’s optimized for JBL’s Pro Sound profile, ensuring vocals cut through the bass-heavy output of PartyBox models like the Encore, Ultimate, or 710.

- Sound Quality: Delivers neutral, professional-grade vocals that blend seamlessly with PartyBox’s bass-forward sound. Users report “crystal clear” audio with minimal distortion, even at high volumes—ideal for karaoke or MCing. EQ adjustments can be made via the connected speaker’s app.
- Connectivity: Plug-and-play; mics auto-pair with the receiver in seconds. No dropouts reported in tests up to 90 feet, thanks to adaptive frequency hopping. Works with single speakers only (not multi-speaker Auracast setups without wiring).
- Endurance: Full charge supports a full night’s event (e.g., 4–6 hours of active use). Pass-through charging lets you plug mics directly into the PartyBox for uninterrupted performance.
- Note: Limited to 2 mics per dongle; for larger setups, add a second system (speakers with multiple inputs required).
