🎤 Compact Erika Wireless Mic System: Perfectly Compatible with Smartphones and Laptops, 1/2 Oz Ultra-Tiny Design with 25-Hr Battery Life, 300' Range, Full-Auto Operation, Mag-Attachment, Ideal for Zoom, Teams, YouTube, and Facebook Review

[Ultra-Tiny Mic, 25-Hour Battery] The ultra-tiny Erika mic (in black or white) is an all-in-one design, including a microphone, 300' range transmitter, and a record-setting 25-hour battery. Featherweight, at only 1⁄2 oz, the mic attaches to your shirt using a magnet. It's easy to forget you're wearing Erika! The mic has no buttons, no body-pack, no under-the-shirt wires. The wireless receiver is USB-powered (no batteries) and requires no drivers or software for installation. [20-Mics to 1-Receiver] Patent-pending dynamic-switching sets Erika apart from all other wireless microphones. Instead of one or two mics to one receiver, Erika can support 20. Using dynamic-switching, Erika constantly evaluates the audio level of all the mics, enabling only one mic while muting all others. Seamlessly switching from mic to mic facilitates natural, uninterrupted conversations. In addition, background noise, echoes, and reverb from inactive mics echoes are blocked. [Fits in Your Shirt Pocket] Erika consists of 3 essential components: one or more wireless microphones (up to 20), a multi-channel wireless receiver, and a USB cable. Just pop open the hard case, connect the receiver to your laptop/phone, attach the mic(s) and start your conference or live stream. A free downloadable Erika app displays the system volume and the individual mic battery level. The app also controls firmware updates, wireless power, spotlight, and rotate to mute. [Work From Anywhere] Ideal for Zoom/Teams conferences, live-streaming, content-creation, vlogging & podcasting, Erika offers superb audio quality with wireless freedom. Expandable up to 20-mics to one receiver, Erika enables 100% coverage of all conference participants from anywhere in the room. Perfect for work from anywhere (WFA) collaborative applications. For live streaming, Erika can save up to 75% of the cost of traditional wireless analog mics and audio mixer-based systems. [Worldwide Compatibility] Erika is compatible with PC, Mac, Linux, iOS, and Android systems. Erika utilizes a standard USB 2.0 audio driver included within the OS. Compatible programs include Zoom/Teams/Meet/RingCentral, OBS/Wirecast, YouTube/FB, and Audacity/Audition. Operating in the 2.4GHz spectrum, Erika will co-exist with WIFI and Bluetooth devices. To avoid interference, Erika employs a sophisticated frequency hopping algorithm, changing channels at over 600 times/second.
