First we made it lighter. At only 21 grams, the CS500 Series features the lightest DECT™ headset on the market (CS540). That means all-day comfort for all-star performance.

Then we made it better. Increased range for maximum mobility, one-touch controls, energy efficient power management, simple plug-and-talk installation — the CS500 Series does it all.
