Wireless headset microphone system

The Logitech KM-G100-1 is a 2.4 GHz RF wireless headset microphone system designed for fitness instructors, online teachers, yoga coaches and spinning instructors. It connects automatically within two seconds and includes a 3.5 mm phone adapter for iPhone and Android devices plus a 6.35 mm adapter for voice amplifiers, audio mixers and outdoor speakers. The sweatproof condenser capsule and waterproof gooseneck are built for high-impact, movement-heavy sessions.

Check device connectors and power

Verify that your camera, smartphone, laptop, PA speaker or voice amplifier has a 3.5 mm or 6.35 mm microphone input before ordering. The system is battery powered and requires a 5 V, 1 A to 2 A charger for reliable charging; lower-current USB ports may not charge the units fully. When using with a laptop or computer, a separate USB sound card is needed because the receiver does not connect directly via USB.

Build around the receiver and adapters

The receiver outputs via 3.5 mm or 6.35 mm plugs, so it fits straight into mixers, portable PA speakers and camera microphone inputs without extra cables. The adjustable headband and flexible gooseneck free the instructor's hands and stay secure during dance, yoga or spinning routines. Active noise cancellation and an 80 dB signal-to-noise ratio on both headphone and microphone paths keep voice capture clear in loud studio or outdoor environments.

Questions about this item

Does the KM-G100-1 package include the USB sound card needed for laptop or computer use?

The box supplies a 3.5 mm phone adapter and a 6.35 mm (1/4") adapter for speakers or PA systems; a USB sound card is not included and must be purchased separately for computer connection.

What is the difference between the KM-G100-1 and the KM-G70 (2TX1RX) model?

The KM-G100-1 is a single headset system (1TX+1RX) for fitness teaching, while the KM-G70 (2TX1RX) supports two transmitters on one receiver for dual-presenter scenarios.

How does the 80 dB signal-to-noise ratio affect voice clarity during a spinning class?

An 80 dB SNR on both headphone and microphone paths keeps background hiss low so the instructor’s voice stays clear over music and bike noise.
