The Trantec S4.04E (S4.04–E–EB–GD5) uses the SJEM77  to ensure a fixed distance between the microphone head and mouth are maintained. Ideal for every application that requires a discrete headworn system for presentation or speech. This results in a faithful reproduction of the spoken word or vocal without variance in volume that can be experienced when using a tie clip solution such as the S4.04L System.

The EM77 headset is designed and ideal for conference use, theatres, educational and houses of workshop. Plugging directly into the S4.04-BTX, the headset will operate for up to 10 hours from a single AA Alkaline Battery. The main receiver for the kit is the S4.04-RX that has output connections via balanced 3 pin XLR and 1/4″ (6.3mm) jack for connection to your microphone or auxiliary inputs.
