1 review for Trantec S4.04 UHF Aerobic Headset Microphone System

  1. Rosella Santoro

    I purchased my first Trantec S4 mic system from Sound Dynamics 7 years ago and only had to replace it last year because someone trod on it. The vocal sound quality is outstanding. I use a head mic with mine and no matter where I am in my venue, the quality and clarity is the same.
    I’ve never suffered that horrible buzzing and interference sound that is so common with other systems and as of yet, I’ve not had to change the Chanel. You literally just plug everything in and you’re good to go. I highly recommend this system and wouldn’t use anything else.
