Mackie OnyxGO Wireless Smartphone Microphone System

OnyxGO Mic is an ultra-compact, self-contained wireless microphone that connects to a smartphone over Bluetooth, using Onyx preamp circuitry for a clean, low-noise vocal signal without a separate receiver.

A headphone output gives real-time stereo monitoring, and the companion app adds voice-changing effects, a 5-band EQ, and reverb, plus automatic lip-sync for video. It records phone calls and video, mixes Bluetooth audio digitally with the mic signal, and includes CR-Buds earphones.
