Eiki EWDC/EWDD Wireless Digital Discussion Unit Battery-Powered Wireless Conference Microphone

The EWDC and EWDD are Eiki's wireless discussion units, low-profile desktop microphones with a pluggable gooseneck capsule, a built-in speaker, and a 2.23-inch backlit OLED display showing signal strength, battery, and speaking time. Either unit can be set as a chairman or delegate station through software, so one hardware SKU covers both roles and a room's mix can change without ordering different units.

A detachable battery pack runs 24 hours continuously on a 4-hour charge (or drops onto a wall adapter for continuous power), and 128-bit encrypted 2.4/5GHz Wi-Fi lets more than 40 units join a single access point, with more APs extending coverage further. Full-digital, uncompressed audio transmission avoids the RF interference and compression artifacts of an analog wireless mic, and the cardioid capsule with anti-wind foam, AGC, AFC, and auto-mix keeps pickup clean at the table.
