Puluz PU646B

A budget wireless radio system with a dual connectivity mode for Android devices, combining dual connectivity (radio + Bluetooth) for flexible use. The kit includes a clip-on transmitter with an electret omnidirectional microphone and a compact receiver with a USB-C receiver for direct Android hookup to a smartphone or tablet. The 20 Hz to 20 kHz frequency range covers the entire spectrum of audible frequencies, though a 65 dB signal-to-noise ratio indicates a basic recording quality suitable for amateur content and simple vlogs.

The Puluz PU646B wireless system features ENC noise and echo cancellation, helping improve speech intelligibility in environments with background noise and reverberation. The ability to switch between the radio link and a Bluetooth connection provides a backup communication channel in case of interference or to save battery life. A 300 mAh battery supports up to 10 hours of continuous operation—a solid figure for a compact device of this class.

A headphone output on the receiver allows you to monitor recording quality, and the included mono earbud for discreet monitoring keeps attention to a minimum. A microphone mute button on the transmitter lets you quickly pause recording. A foam windscreen reduces breathing and wind noise during outdoor shoots. A protective case simplifies transport and storage between shoots.
