Halter Technical Microsone Discreet Audio Monitoring System

Using the transmitters you already own, the Halter Technical Microsone is a discreet audio monitoring system that lets on-camera and on-stage talent hear their IFB feed with no wires in sight.

The system pairs two rechargeable Bluetooth earbuds with a beltpack transceiver and a charging case. The sound technician sets up the frequencies, and the wearer controls the volume.

Microsone Earbuds

Each earbud measures 0.70 inch (18 mm) and sits hidden in the ear canal. It has no buttons or dials, it comes in light and dark skin tones, and its built-in lithium battery means no disposable hearing aid batteries. A beep warns the wearer when the battery is near empty, so the second earbud can take over. Each one pairs separately and can also pair with another Bluetooth device, such as a phone.

Control Pack Transceiver

The Control Pack receives any analog FM transmitter from 174 to 217 MHz and 470 to 608 MHz, then sends the audio to the earbuds over Bluetooth. It holds four banks of eight channels, reprogrammed from its front panel with no computer. Its antennas are internal, so it hides easily on the wearer or nearby. A key lock stops talent from changing settings.

It runs on two AA batteries or 5 V through its USB-C port, which also charges rechargeable NiMH AA batteries. The top 3.5 mm jack works as a line-level input or as a headphone output, so the pack can also serve as a wired IFB receiver.

Charging Case

The case charges both earbuds at once. Its OLED display shows the case’s own battery percentage and the charging status of each earbud, and it recharges through USB-C.
