The JBL Partybox Wireless Microphone Set allows you to move freely during performances or karaoke sessions when paired with any JBL PartyBox speaker, such as the Encore or Ultimate. This set includes two microphones and a wireless receiver dongle that connects via a 6.35mm jack, utilizing AES-128 encryption for secure transmission across a range of up to 30 meters. To ensure clear audio without interference, the system employs adaptive frequency and channel selection within the 2404 – 2478 MHz band, while maintaining a low latency of under 12 ms for real-time responsiveness. Each microphone is built around a 16 mm ECM cardioid dynamic capsule with an integrated shock mount and foam pop filter to reduce unwanted noise and plosives. These units are lightweight at 270 g and offer a frequency response from 50 Hz to 15 kHz, providing a balanced sound for various voice types. You can rely on the 600mAh Li-ion batteries for up to 20 hours of use, while the receiver dongle lasts up to 12 hours on its own 700mAh battery. Charging is handled via USB Type-C ports, taking less than 2.5 hours to reach full capacity when powered off. This setup is well-suited for hosts and performers who want to engage with their audience without being tethered by cables, benefiting from a signal-to-noise ratio of 59 dBA and low total harmonic distortion.
