Wayne County (Mich.) Sheriff’s deputies field-tested FreeLinc’s FreeMotion 200, a wireless headset for two-way radios, during last month’s Major League Baseball All-Star Game in Detroit, according to the company.

The headsets operate on LibertyLink technology--a near-field magnetic induction technology that confines communication signals to a user's personal space and protects them from eavesdroppers or interference--developed by Aura Communications Technology.

The headset also features voice-operated transmission (VOX) to enable hands-free communication and offers up to 20 hours of talk time on one battery charge in VOX mode.

FreeMotion 200 will be available this fall, according to the company.
