Tired of hoarse throats and lost back rows? Clip the K500 to your waistband and speak at a normal volume that carries up to 500m2.
Hands-free amplification that moves with you
Carry it all day
The body is light plastic with a matte finish, so it sits on your waistband without pulling at your clothes. Long sessions stop feeling like carrying gear.

The K500 is rated to cover up to 500m2. You keep your normal speaking voice and the group at the back still hears every point without you raising your volume.

Projecting all day should not cost you your voice
The voice that gives out by noon
By the third lesson of the day your throat is raw and the back row is still asking you to repeat yourself. Pushing harder only makes the strain worse, and the people furthest away still miss the points that matter.
Found a way to speak without shouting
The K500 clips to your waistband and the headset mic sits close to your mouth. You speak at a normal volume and the speaker carries it, so the sound stays natural instead of strained. Your hands stay free for slides, notes and gestures.
Your voice, heard everywhere
Finish the session with a fresh voice and a room that followed every sentence. The same unit works in a classroom, on a walking tour or at an open-air promotion, so one small device covers the whole week.

Questions and answers
The K500 is rated to cover up to 500m2. That fits most classrooms, lecture halls and open tour groups. A very large space may need a few minutes of volume tuning, and the mid level is usually enough to start.
The body is matte plastic built to clip on and ride at the waist all day. It is light, which is why it stays comfortable through long sessions. Keep it off hard floors and out of rain, and it will handle the daily routine of teaching or guiding.
Charge the built-in battery with the included micro USB cable before the first use. Switch on Bluetooth and the K500 auto pairs after the first connection, so most sessions start with one tap.
A PA system needs stands, cables and a second person to set up in many rooms. A megaphone is awkward to hold and distorts at volume. The K500 clips to your waistband, includes a headset mic, and leaves both hands free for slides, notes and gestures.
Yes. The same unit works on a walking tour, a meeting room or an open-air promotion. Clipped to the waist or worn on a shoulder strap, it keeps your voice carrying without shouting over the street.
