The MIPRO MT-101ACT Wireless Handheld Transmitter Microphone is the world's first personal multi-purpose rechargeable wireless microphone. It features a built-in 3.5 mm mini-jack line-input (mono) that accepts an external portable music player such as an iPod/MP3 or CD player for sound amplification. The same wireless microphone can be used in up to 97 different rooms - all with different frequencies to avoid crosstalk or loss of privacy. The MT-101ACT is powered via built-in rechargeable or disposable alkaline batteries. It includes a slide control for wireless volume adjustment and level switch of the speaker.

The MT-101ACT can be handheld or worn as a neck lanyard for hands-free operation with an optional lapel or head-worn microphone. It operates up to 24 hours with a 3-hour fast charge. The included MP-101ACT drop-in charger ensures the microphone is always charged and ready to use.
