The 2.4G wireless teachers microphone developed specifically for the education industry, 2.4G wireless transmission technology. Using the ID code of encrypted digital transmission technology, modulation/demodulation process using the full digital. Perfect exterior design, humane ways to wear, good acoustic sound transmission, with a clear voice, strong anti-interference, versatility; completely solve the traditional wireless microphone channeling frequency interference. The patented neck wear way, the complete liberation teacher's hands, 50 g weight, convenient to wear for a long time, intelligent power switch, automatically adjusts the switching adjust to school adding and dropping classes time, and the receiver with USB data interface ,support import settings through ST01 teaching software, avoid complicated operations, a unique program designed to completely solve the teacher forgets to turn off the microphone resulting string sound, sound transmission problems.

Product Features:

1. Small size and light weight: only 50g include battery. Convenient to carry, both clean and hygienic and does not require special management. This is the most comfortable teacher microphone system in the market now. Even if the speakers standing closed to speakers 1M, no any squeaking;

2. Environmental protection: ultra-low transmitting power, less than 1% electromagnetic radiation of the telephone. A veritable "green wireless microphones”. Rechargeable lithium battery, to avoid the disposable dry battery damage to environment.

Product performance:

1. anti-jamming performance: professional ID code encryption transmission technology, unique ID code for each receiver, ID code up to a million, solves the traditional wireless microphone frequency interference completely. With automatically mute function, users do not speak, or in a weak signal status receiver completely mute. 

2. Compatibility: the microphone can be use in all classrooms. Microphone can search frequency automatically, users simply to complete synchronizes frequency with receiver in 2 meters by 1 second. Each teacher has a microphone, Convenient to carry, both clean and hygienic and does not require special management.

3. Big batteries capacity: working time more than 6 hours, Built-in with low-voltage alarm, charging indicator and shutdown automatically the charge when fully charged.
