Trying to teach a fitness class can lead to confusion if you don’t have a quality microphone and speaker system to project instructions clearly. As a fitness instructor, hands-free full body movement is essential for a professional fitness presentation. Most headset mics require a body pack transmitter, wired directly to your headset microphone, which can be awkward and difficult to place appropriately on workout clothing. Additionally, body pack cables often interfere with movement during your workout instruction, causing distraction and frustration.

The EVO True Wireless headset mic solves all these problems and minimizes the equipment being worn. The EVO is a 16 channel UHF frequency dual ear headset mic that incorporates both headband and wireless transmitter into one compact, self-contained ergonomic design. The rechargeable mic is both splash and sweat resistant. The EVO offers a patented design that allows freedom of movement, eliminating both cable and body pack by relocating the transmitter behind the ear on the headset, for easy, carefree fitness instruction that never interferes with floor exercises. The EVO is lightweight, comfortable, and stays in place even during the most rigorous exercise routine.

The EVO Wireless Headset features a noise canceling, condenser mic element, enabling exercise instructors to project their voice clearly while reducing external ambient noise or music interference. The EVO Wireless headset mic features a rechargeable battery (up to 4+ hours battery life), power supply included for recharging. The EVO headset is compatible with the SP-25R Scan16 true diversity receiver (one or two EVO headset options), the GXE Group.X 10” fitness speaker PA system, and GXE-LITE Group.X Lite 5.25” full range portable speaker PA system. Take your fitness, gym, yoga, aerobics, or water aerobics instruction class to the next level with the EVO!
