USB Microphone System (2.4 GHz) for Zoom, Livestreaming, Webinars, Podcasting, and Content Creation.
Key Highlights
  • 2.4 GHz Wireless Microphone
  • 300' Range
  • For Zoom, Livestreaming, et al.


The Convergent Design Erika Wireless USB Microphone is ideal for Zoom, live streaming, webinars, podcasting, and content creation. The Erika Wireless USB receiver seamlessly connects to your PC/Mac without the added cost/complexity of an external converter box. USB audio compatibility enables a wide range of applications such as Zoom, Teams, WebEx, OBS, VMix, Audacity, Audition, Premiere, FCP, GarageBand, and any USB audio program supporting 22.05/44.1 kHz sampling.

CD-Quality Audio Without the Wires

Typically worn on your shirt/blouse, the Erika mic makes it easy to maintain a consistent audio level, and you no longer need a pop-filter. Quality digital audio processing, combined with noise and echo reduction, maintains excellent sound quality, even in challenging environments. Room echo and laptop fan noise are diminished, creating a far more natural-sounding voice. Innovative AutoMute helps eliminate embarrassing "hot-mic" moments by automatically muting and unmuting your mic as you leave and re-enter your area, without pops or clicks.

Tiny Visual Footprint

The miniature microphone features a non-reflective, black, matte finish with no distracting visible markings. Measuring just 1.5" x 0.8" x 0.4" (38mm x 21mm x 10mm), it is designed to go unnoticed and is comparable in size to common lavalier mics. Weighing only 0.03 lb (16 g), simple magnetic attachment allows greater mounting flexibility, eliminating the need for intrusive wires and body packs worn under clothing.

Industry-leading 24-hour runtime (typical in voice mode) eliminates battery swap-out/recharge downtime issues. Fifteen minutes of charge time provides 2 hours of runtime; full charge in under 3 hours. Automatic power-on/power-off minimizes dead batteries- pick-up to power-up, set face-down to power-down.

Unlike wired USB mics, Erika requires almost no desktop space. The mic will not obstruct your face or view, and the system is easy to transport. The kit includes a small white plastic stand to hold the wireless USB receiver in a vertical position, maximizing range. No driver or app is required. Just plug the receiver into a USB port on your laptop, pick up the mic, and start talking.

Designed to coexist with WiFi and Bluetooth devices, Erika requires no channel or group setup. Auto-adaptive frequency hopping continuously optimizes the RF transmission without user intervention. Operating at 2.4 GHz, frequency band obsolescence (common in analog mics) is never a concern.

Configurable Dual-Use

Erika is an ideal wearable mic for individual speakers during online meetings, live streaming, podcasts, and webinars. Additionally, the low-noise, high sensitivity mic is perfect for conference room applications. Placed in the center of the table, Erika delivers excellent audio quality for 2-4 participants. Five power-range options, voice mode (22.05 kHz) and music mode (44.1 kHz), allow users to trade-off range, audio bandwidth, and battery runtime.
